117-404: " Attention Is All You Need " is a 2017 landmark research paper in machine learning authored by eight scientists working at Google. The paper introduced a new deep learning architecture known as the transformer , based on the attention mechanism proposed in 2014 by Bahdanau et al. It is considered a foundational paper in modern artificial intelligence , as the transformer approach has become

351-539: A manuscript to a publisher, is divided into two distinct phases: peer review and production. The process of peer review is organized by the journal editor and is complete when the content of the article, together with any associated images, data, and supplementary material are accepted for publication. The peer review process is increasingly managed online, through the use of proprietary systems, commercial software packages, or open source and free software. A manuscript undergoes one or more rounds of review; after each round,

468-538: A proof reader onto a clean version of the proof. In the early 21st century, this process was streamlined by the introduction of e-annotations in Microsoft Word , Adobe Acrobat , and other programs, but it still remained a time-consuming and error-prone process. The full automation of the proof correction cycles has only become possible with the onset of online collaborative writing platforms, such as Authorea , Google Docs , Overleaf , and various others, where

Some journals, particularly newer ones, are now published in electronic form only . Paper journals are now generally made available in electronic form as well, both to individual subscribers, and to libraries. Almost always these electronic versions are available to subscribers immediately upon publication of

702-476: A copy of their published articles available free for all on the web. Some important results in mathematics have been published only on arXiv . The Journal des sçavans (later spelled Journal des savants ), established by Denis de Sallo , was the earliest academic journal published in Europe. Its content included obituaries of famous men, church history, and legal reports. The first issue appeared as

819-438: A first tenure-track job, and a published or forthcoming book is now often required before tenure. Some critics complain that this de facto system has emerged without thought to its consequences; they claim that the predictable result is the publication of much shoddy work, as well as unreasonable demands on the already limited research time of young scholars. To make matters worse, the circulation of many humanities journals in

936-401: A growth in academic publishing in developing countries as they become more advanced in science and technology. Although the large majority of scientific output and academic documents are produced in developed countries, the rate of growth in these countries has stabilized and is much smaller than the growth rate in some of the developing countries. The fastest scientific output growth rate over

It also remains unclear whether this is practical in fields outside the sciences, where there is much less availability of outside funding. In 2006, several funding agencies , including the Wellcome Trust and several divisions of the Research Councils in

Available data indicate that these companies have profit margins of around 40% making it one of the most profitable industries, especially compared to the smaller publishers, which likely operate with low margins. These factors have contributed to the " serials crisis " – total expenditures on serials increased 7.6% per year from 1986 to 2005, yet

However, this method did not work well. Robert K. Merton , a sociologist, found that 92% of cases of simultaneous discovery in the 17th century ended in dispute. The number of disputes dropped to 72% in the 18th century, 59% by

1638-425: A paper is an academic work that is usually published in an academic journal . It contains original research results or reviews existing results. Such a paper, also called an article, will only be considered valid if it undergoes a process of peer review by one or more referees (who are academics in the same field) who check that the content of the paper is suitable for publication in the journal. A paper may undergo

1755-476: A remote service oversees the copy-editing interactions of multiple authors and exposes them as explicit, actionable historic events. At the end of this process, a final version of record is published. From time to time some published journal articles have been retracted for different reasons, including research misconduct. Academic authors cite sources they have used, in order to support their assertions and arguments and to help readers find more information on

1872-448: A series of reviews, revisions, and re-submissions before finally being accepted or rejected for publication. This process typically takes several months. Next, there is often a delay of many months (or in some fields, over a year) before an accepted manuscript appears. This is particularly true for the most popular journals where the number of accepted articles often outnumbers the space for printing. Due to this, many academics self-archive

1989-562: A simplified variant of the forget gate LSTM called Gated recurrent unit (GRU). (Rupesh Kumar Srivastava, Klaus Greff, and Schmidhuber, 2015) used LSTM principles to create the Highway network , a feedforward neural network with hundreds of layers, much deeper than previous networks. Concurrently, the ResNet architecture was developed. It is equivalent to an open-gated or gateless highway network. A modern upgrade of LSTM called xLSTM

2106-505: A supervised fashion on a set of training sequences, using an optimization algorithm like gradient descent combined with backpropagation through time to compute the gradients needed during the optimization process, in order to change each weight of the LSTM network in proportion to the derivative of the error (at the output layer of the LSTM network) with respect to corresponding weight. A problem with using gradient descent for standard RNNs

2223-546: A twelve-page quarto pamphlet on Monday, 5 January 1665, shortly before the first appearance of the Philosophical Transactions of the Royal Society , on 6 March 1665. The publishing of academic journals has started in the 17th century, and expanded greatly in the 19th. At that time, the act of publishing academic inquiry was controversial and widely ridiculed. It was not at all unusual for

2340-516: A vocabulary of 165,000 words. The approach used "dialog session-based long-short-term memory". 2018: OpenAI used LSTM trained by policy gradients to beat humans in the complex video game of Dota 2, and to control a human-like robot hand that manipulates physical objects with unprecedented dexterity. 2019: DeepMind used LSTM trained by policy gradients to excel at the complex video game of Starcraft II . Aspects of LSTM were anticipated by "focused back-propagation" (Mozer, 1989), cited by

Academic publishing Most established academic disciplines have their own journals and other outlets for publication, although many academic journals are somewhat interdisciplinary , and publish work from several distinct fields or subfields. There

2691-558: Is a central concept for most academic publishing; other scholars in a field must find a work sufficiently high in quality for it to merit publication. A secondary benefit of the process is an indirect guard against plagiarism since reviewers are usually familiar with the sources consulted by the author(s). The origins of routine peer review for submissions dates to 1752 when the Royal Society of London took over official responsibility for Philosophical Transactions. However, there were some earlier examples. While journal editors largely agree

2808-477: Is a large industry which generated $ 23.5 billion in revenue in 2011; $ 9.4 billion of that was specifically from the publication of English-language scholarly journals. The overall number of journals contained in the WOS database increased from around 8,500 in 2010 to around 9,400 in 2020, while the number of articles published increased from around 1.1 million in 2010 to 1.8 million in 2020. Most scientific research

2925-399: Is accessible only after the last word of the source text was processed. Although in theory such a vector retains the information about the whole original sentence, in practice the information is poorly preserved. This is because the input is processed sequentially by one recurrent network into a fixed -size output vector, which is then processed by another recurrent network into an output. If

3042-432: Is also a tendency for existing journals to divide into specialized sections as the field itself becomes more specialized. Along with the variation in review and publication procedures, the kinds of publications that are accepted as contributions to knowledge or research differ greatly among fields and subfields. In the sciences, the desire for statistically significant results leads to publication bias . Academic publishing

3159-434: Is also considered that "Online scientific interaction outside the traditional journal space is becoming more and more important to academic communication". In addition, experts have suggested measures to make the publication process more efficient in disseminating new and important findings by evaluating the worthiness of publication on the basis of the significance and novelty of the research finding. In academic publishing,

3276-410: Is an LSTM that takes in a sequence of tokens and turns it into a vector. The decoder is another LSTM that converts the vector into a sequence of tokens. Similarly, another 130M-parameter model used gated recurrent units (GRU) instead of LSTM. Later research showed that GRUs are neither better nor worse than LSTMs for seq2seq. These early seq2seq models had no attention mechanism, and the state vector

3393-418: Is an important aspect in peer review. The evaluation of quality of journals is based also on rejection rate . The best journals have the highest rejection rates (around 90–95%). American Psychological Association journals' rejection rates ranged "from a low of 35 per cent to a high of 85 per cent." The complement is called "acceptance rate". The process of academic publishing, which begins when authors submit

3510-490: Is as much based on peer reviewing as traditional publishing, the quality should be the same (recognizing that both traditional and open access journals have a range of quality). In several regions, including the Arab world , the majority of university academics prefer open access publishing without author fees, as it promotes equal access to information and enhances scientific advancement, a previously unexplored but crucial topic for

3627-400: Is because it "emulates searching through a source sentence during decoding a translation". The relative performances were compared between global (that of RNNsearch ) and local (sliding window) attention model architectures for machine translation, finding that mixed attention had higher quality than global attention, while local attention reduced translation time.

Unlike the sciences, research is most often an individual process and is seldom supported by large grants. Journals rarely make profits and are typically run by university departments. The following describes the situation in the United States. In many fields, such as literature and history, several published articles are typically required for

An equally prestigious site of publication within U.S. computer science are some academic conferences . Reasons for this departure include a large number of such conferences, the quick pace of research progress, and computer science professional society support for the distribution and archiving of conference proceedings . Since 2022,

3978-680: Is initially published in scientific journals and considered to be a primary source . Technical reports , for minor research results and engineering and design work (including computer software), round out the primary literature. Secondary sources in the sciences include articles in review journals (which provide a synthesis of research articles on a topic to highlight advances and new lines of research), and books for large projects, broad arguments, or compilations of articles. Tertiary sources might include encyclopedias and similar works intended for broad public consumption or academic libraries. A partial exception to scientific publication practices

Both open and closed journals are sometimes funded by the author paying an article processing charge , thereby shifting some fees from the reader to the researcher or their funder. Many open or closed journals fund their operations without such fees and others use them in predatory publishing . The Internet has facilitated open access self-archiving , in which authors themselves make

4212-401: Is made in analogy with long-term memory and short-term memory and their relationship, studied by cognitive psychologists since the early 20th century. An LSTM unit is typically composed of a cell and three gates : an input gate , an output gate , and a forget gate . The cell remembers values over arbitrary time intervals, and the gates regulate the flow of information into and out of

4329-656: Is maximised because, quoting the Library of Trinity College Dublin: Open Access is often confused with specific funding models such as Article Processing Charges (APC) being paid by authors or their funders, sometimes misleadingly called "open access model". The reason this term is misleading is due to the existence of many other models, including funding sources listed in the original the Budapest Open Access Initiative Declaration : "the foundations and governments that fund research,

However, the United States' output dropped from 52.3% to 49.4% of the world's total, and its portion of the top one percent dropped from 65.6% to 62.8%. Iran, China, India , Brazil , and South Africa were the only developing countries among

5499-405: The humanities is in principle similar to publishing elsewhere in the academy; a range of journals, from general to extremely specialized, are available, and university presses issue many new humanities books every year. The arrival of online publishing opportunities has radically transformed the economics of the field and the shape of the future is controversial. Unlike science, where timeliness

Transformer architecture is now used in many generative models that contribute to the ongoing AI boom . In language modelling, ELMo (2018) was a bi-directional LSTM that produces contextualized word embeddings , improving upon

5733-473: The 1990s declined to almost untenable levels, as many libraries cancelled subscriptions, leaving fewer and fewer peer-reviewed outlets for publication; and many humanities professors' first books sell only a few hundred copies, which often does not pay for the cost of their printing. Some scholars have called for a publication subvention of a few thousand dollars to be associated with each graduate student fellowship or new tenure-track hire, in order to alleviate

Oxford University Press, with over 300 journals, has fees ranging from £1000-£2500, with discounts of 50% to 100% to authors from developing countries. Wiley Blackwell has 700 journals available, and they charge different amounts for each journal. Springer, with over 2600 journals, charges US$ 3000 or EUR 2200 (excluding VAT). A study found that

6318-711: The ARL found that in "1986, libraries spent 44% of their budgets on books compared with 56% on journals; twelve years later, the ratio had skewed to 28% and 72%." Meanwhile, monographs are increasingly expected for tenure in the humanities. In 2002 the Modern Language Association expressed hope that electronic publishing would solve the issue. In 2009 and 2010, surveys and reports found that libraries faced continuing budget cuts, with one survey in 2009 finding that 36% of UK libraries had their budgets cut by 10% or more, compared to 29% with increased budgets.

Some fields, like economics, may have very "hard" or highly quantitative standards for publication, much like the natural sciences. Others, like anthropology or sociology, emphasize field work and reporting on first-hand observation as well as quantitative work. Some social science fields, such as public health or demography , have significant shared interests with professions like law and medicine , and scholars in these fields often also publish in professional magazines .

Academic copy editing seeks to ensure that an article conforms to

7722-470: The authors increased the learning rate linearly for the first 4000 (warmup) steps and decreased it proportionally to inverse square root of the current step number. Dropout layers were applied to the output of each sub-layer before normalization, the sums of the embeddings, and the positional encodings. The dropout rate was set to 0.1.

A (rounded) value of 1 signifies retention of the information, and a value of 0 represents discarding. Input gates decide which pieces of new information to store in the current cell state, using the same system as forget gates. Output gates control which pieces of information in

8190-439: The commercial publishers raised the subscription prices significantly, they lost little of the market, due to the inelastic demand for these journals. Although there are over 2,000 publishers, five for-profit companies ( Reed Elsevier , Springer Science+Business Media , Wiley-Blackwell , Taylor & Francis , and SAGE ) accounted for 50% of articles published in 2013. (Since 2013, Springer Science+Business Media has undergone

LSTM has wide applications in classification , data processing , time series analysis tasks, speech recognition , machine translation , speech activity detection, robot control , video games , and healthcare . In theory, classic RNNs can keep track of arbitrary long-term dependencies in

8541-485: The desire to maximize publishing fees could cause some journals to relax the standard of peer review. Although, similar desire is also present in the subscription model, where publishers increase numbers or published articles in order to justify raising their fees. It may be criticized on financial grounds as well because the necessary publication or subscription fees have proven to be higher than originally expected. Open access advocates generally reply that because open access

The intuition behind the LSTM architecture is to create an additional module in a neural network that learns when to remember and when to forget pertinent information. In other words, the network effectively learns which information might be needed later on in a sequence and when that information is no longer needed. For instance, in the context of natural language processing ,

9126-517: The financial pressure on journals. Under Open Access, the content can be freely accessed and reused by anyone in the world using an Internet connection. The terminology going back to Budapest Open Access Initiative , Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities , and Bethesda Statement on Open Access Publishing . The impact of the work available as Open Access

9243-573: The forget gate f {\displaystyle f} or the memory cell c {\displaystyle c} , depending on the activation being calculated. In this section, we are thus using a "vector notation". So, for example, c t ∈ R h {\displaystyle c_{t}\in \mathbb {R} ^{h}} is not just one unit of one LSTM cell, but contains h {\displaystyle h} LSTM cell's units. See for an empirical study of 8 architectural variants of LSTM. The compact forms of

9360-431: The input is long, then the output vector would not be able to contain all relevant information, degrading the output. As evidence, reversing the input sentence improved seq2seq translation. The RNNsearch model introduced an attention mechanism to seq2seq for machine translation to solve the bottleneck problem (of the fixed-size output vector), allowing the model to process long-distance dependencies more easily. The name

9477-545: The input sequences. The problem with classic RNNs is computational (or practical) in nature: when training a classic RNN using back-propagation , the long-term gradients which are back-propagated can "vanish" , meaning they can tend to zero due to very small numbers creeping into the computations, causing the model to effectively stop learning. RNNs using LSTM units partially solve the vanishing gradient problem , because LSTM units allow gradients to also flow with little to no attenuation. However, LSTM networks can still suffer from

9594-418: The journal's house style , that all of the referencing and labelling is correct, and that the text is consistent and legible; often this work involves substantive editing and negotiating with the authors. Because the work of academic copy editors can overlap with that of authors' editors , editors employed by journal publishers often refer to themselves as "manuscript editors". During this process, copyright

9711-525: The last two decades has been in the Middle East and Asia with Iran leading with an 11-fold increase followed by the Republic of Korea, Turkey, Cyprus, China, and Oman. In comparison, the only G8 countries in top 20 ranking with fastest performance improvement are, Italy which stands at tenth and Canada at 13th globally. By 2004, it was noted that the output of scientific papers originating from

9828-507: The latter half of the 19th century, and 33% by the first half of the 20th century. The decline in contested claims for priority in research discoveries can be credited to the increasing acceptance of the publication of papers in modern academic journals, with estimates suggesting that around 50 million journal articles have been published since the first appearance of the Philosophical Transactions . The Royal Society

9945-465: The line of research from bag of words and word2vec . It was followed by BERT (2018), an encoder-only Transformer model. In 2019 October, Google started using BERT to process search queries. In 2020, Google Translate replaced the previous RNN-encoder–RNN-decoder model by a Transformer-encoder–RNN-decoder model. Starting in 2018, the OpenAI GPT series of decoder-only Transformers became state of

10062-472: The lowercase variables represent vectors. Matrices W q {\displaystyle W_{q}} and U q {\displaystyle U_{q}} contain, respectively, the weights of the input and recurrent connections, where the subscript q {\displaystyle _{q}} can either be the input gate i {\displaystyle i} , output gate o {\displaystyle o} ,

10179-427: The main architecture of large language models like those based on GPT . At the time, the focus of the research was on improving Seq2seq techniques for machine translation , but the authors go further in the paper, foreseeing the technique's potential for other tasks like question answering and what is now known as multimodal Generative AI . The paper's title is a reference to the song " All You Need Is Love " by

10296-412: The network can learn grammatical dependencies. An LSTM might process the sentence " Dave , as a result of his controversial claims, is now a pariah" by remembering the (statistically likely) grammatical gender and number of the subject Dave , note that this information is pertinent for the pronoun his and note that this information is no longer important after the verb is . In the equations below,

10413-489: The number of serials purchased increased an average of only 1.9% per year. Unlike most industries, in academic publishing the two most important inputs are provided "virtually free of charge". These are the articles and the peer review process. Publishers argue that they add value to the publishing process through support to the peer review group, including stipends, as well as through typesetting, printing, and web publishing. Investment analysts, however, have been skeptical of

10530-544: The official blog post, the new model cut transcription errors by 49%. 2016: Google started using an LSTM to suggest messages in the Allo conversation app. In the same year, Google released the Google Neural Machine Translation system for Google Translate which used LSTMs to reduce translation errors by 60%. Apple announced in its Worldwide Developers Conference that it would start using

10647-403: The output layer, the error remains in the LSTM unit's cell. This "error carousel" continuously feeds error back to each of the LSTM unit's gates, until they learn to cut off the value. Many applications use stacks of LSTM RNNs and train them by connectionist temporal classification (CTC) to find an RNN weight matrix that maximizes the probability of the label sequences in a training set, given

10764-403: The paper version, or even before; sometimes they are also made available to non-subscribers, either immediately (by open access journals ) or after an embargo of anywhere from two to twenty-four months or more, in order to protect against loss of subscriptions. Journals having this delayed availability are sometimes called delayed open access journals . Ellison in 2011 reported that in economics

10881-444: The picture may suggest). In other words, the gates i , o {\displaystyle i,o} and f {\displaystyle f} calculate their activations at time step t {\displaystyle t} (i.e., respectively, i t , o t {\displaystyle i_{t},o_{t}} and f t {\displaystyle f_{t}} ) also considering

10998-505: The published papers the next year, is smaller although also increasing. Developing countries continue to find ways to improve their share, given research budget constraints and limited resources. There is increasing frustration amongst OA advocates, with what is perceived as resistance to change on the part of many of the established academic publishers. Publishers are often accused of capturing and monetising publicly funded research, using free academic labour for peer review, and then selling

11115-519: The region's higher education. It has also been argued that good science done by academic institutions who cannot afford to pay for open access might not get published at all, but most open access journals permit the waiver of the fee for financial hardship or authors in underdeveloped countries . In any case, all authors have the option of self-archiving their articles in their institutional repositories or disciplinary repositories in order to make them open access , whether or not they publish them in

11232-501: The resulting publications back to academia at inflated profits. Such frustrations sometimes spill over into hyperbole, of which "publishers add no value" is one of the most common examples. However, scholarly publishing is not a simple process, and publishers do add value to scholarly communication as it is currently designed. Kent Anderson maintains a list of things that journal publishers do which currently contains 102 items and has yet to be formally contested from anyone who challenges

11349-449: The same issue with recurrent networks, which is that they are hard to parallelize , which prevented them to be accelerated on GPUs. In 2016, decomposable attention applied a self-attention mechanism to feedforward networks , which are easy to parallelize, and achieved SOTA result in textual entailment with an order of magnitude less parameters than LSTMs. One of its authors, Jakob Uszkoreit, suspected that attention without recurrence

11466-498: The scholarly record. Long short-term memory Long short-term memory ( LSTM ) is a type of recurrent neural network (RNN) aimed at mitigating the vanishing gradient problem commonly encountered by traditional RNNs. Its relative insensitivity to gap length is its advantage over other RNNs, hidden Markov models , and other sequence learning methods. It aims to provide a short-term memory for RNN that can last thousands of timesteps (thus " long short-term memory"). The name

11583-416: The size of the context window. The linearly scaling fast weight controller (1992) learns to compute a weight matrix for further processing depending on the input. One of its two networks has "fast weights" or "dynamic links" (1981). A slow neural network learns by gradient descent to generate keys and values for computing the weight changes of the fast neural network which computes answers to queries. This

11700-413: The standard architecture for long sequence modelling until the 2017 publication of Transformers. However, LSTM still used sequential processing, like most other RNNs. Specifically, RNNs operate one token at a time from first to last; they cannot operate in parallel over all tokens in a sequence. Modern Transformers overcome this problem, but unlike RNNs, they require computation time that is quadratic in

11817-477: The subject. It also gives credit to authors whose work they use and helps avoid plagiarism . The topic of dual publication (also known as self-plagiarism) has been addressed by the Committee on Publication Ethics (COPE), as well as in the research literature itself. Each scholarly journal uses a specific format for citations (also known as references). Among the most common formats used in research papers are

11934-468: The system is essential to quality control in terms of rejecting poor quality work, there have been examples of important results that are turned down by one journal before being taken to others. Rena Steinzor wrote: Perhaps the most widely recognized failing of peer review is its inability to ensure the identification of high-quality work. The list of important scientific papers that were initially rejected by peer-reviewed journals goes back at least as far as

12051-401: The team that the Transformer is a general purpose language model, and not just good for translation. As of 2024, the paper has been cited more than 100,000 times. The authors of the paper are: Ashish Vaswani , Noam Shazeer , Niki Parmar, Jakob Uszkoreit, Llion Jones, Aidan Gomez , Lukasz Kaiser, and Illia Polosukhin. All eight authors were "equal contributors" to the paper; the listed order

12168-440: The time step. Letting the superscripts d {\displaystyle d} and h {\displaystyle h} refer to the number of input features and number of hidden units, respectively: The figure on the right is a graphical representation of an LSTM unit with peephole connections (i.e. a peephole LSTM). Peephole connections allow the gates to access the constant error carousel (CEC), whose activation

12285-553: The universities and laboratories that employ researchers, endowments set up by discipline or institution, friends of the cause of open access, profits from the sale of add-ons to the basic texts, funds freed up by the demise or cancellation of journals charging traditional subscription or access fees, or even contributions from the researchers themselves". For more recent open public discussion of open access funding models, see Flexible membership funding model for Open Access publishing with no author-facing charges . Prestige journals using

12402-415: The value added by for-profit publishers, as exemplified by a 2005 Deutsche Bank analysis which stated that "we believe the publisher adds relatively little value to the publishing process... We are simply observing that if the process really were as complex, costly and value-added as the publishers protest that it is, 40% margins wouldn't be available." A crisis in academic publishing is "widely perceived";

12519-468: The value of publishers. Many items on the list could be argued to be of value primarily to the publishers themselves, e.g. "Make money and remain a constant in the system of scholarly output". However, others provide direct value to researchers and research in steering the academic literature. This includes arbitrating disputes (e.g. over ethics, authorship), stewarding the scholarly record, copy-editing, proofreading, type-setting, styling of materials, linking

12636-476: The western monopoly of science-publishing, "by August 2021, at least 210,000 new papers on covid-19 had been published, according to a Royal Society study. Of the 720,000-odd authors of these papers, nearly 270,000 were from the US, the UK, Italy or Spain." In the 1960s and 1970s, commercial publishers began to selectively acquire "top-quality" journals that were previously published by nonprofit academic societies. When

12753-434: Was LSTM (1995), a RNN which used various innovations to overcome the vanishing gradient problem, allowing efficient learning of long-sequence modelling. One key innovation was the use of an attention mechanism which used neurons that multiply the outputs of other neurons, so-called multiplicative units . Neural networks using multiplicative units were later called sigma-pi networks or higher-order networks . LSTM became

12870-450: Was done by using plain recurrent neural networks (RNNs). A well-cited early example was the Elman network (1990). In theory, the information from one token can propagate arbitrarily far down the sequence, but in practice the vanishing-gradient problem leaves the model's state at the end of a long sentence without precise, extractable information about preceding tokens. A key breakthrough

12987-452: Was later shown to be equivalent to the unnormalized linear Transformer. The idea of encoder-decoder sequence transduction had been developed in the early 2010s (see previous papers). The papers most commonly cited as the originators that produced seq2seq are two concurrently published papers from 2014. A 380M-parameter model for machine translation uses two long short-term memories (LSTM). Its architecture consists of two parts. The encoder

13104-545: Was not until the middle of the 20th century that peer review became the standard. The COVID-19 pandemic hijacked the entire world of basic and clinical science, with unprecedented shifts in funding priorities worldwide and a boom in medical publishing, accompanied by an unprecedented increase in the number of publications. Preprints servers become much popular during the pandemic, the Covid situation has an impact also on traditional peer-review . The pandemic has also deepened

13221-435: Was proposed in the " Attention is all you need " paper. At the time, the focus of the research was on improving seq2seq for machine translation , by removing its recurrence to process all tokens in parallel, but preserving its dot-product attention mechanism to keep its text processing performance. Its parallelizability was an important factor to its widespread use in large neural networks. Already in spring 2017, even before

13338-435: Was published in 1997 in the journal Neural Computation . By introducing Constant Error Carousel (CEC) units, LSTM deals with the vanishing gradient problem . The initial version of LSTM block included cells, input and output gates. ( Felix Gers , Jürgen Schmidhuber, and Fred Cummins, 1999) introduced the forget gate (also called "keep gate") into the LSTM architecture in 1999, enabling the LSTM to reset its own state. This

13455-549: Was randomized. The Wired article highlights the group's diversity: Six of the eight authors were born outside the United States; the other two are children of two green-card-carrying Germans who were temporarily in California and a first-generation American whose family had fled persecution, respectively. By 2023, all eight authors had left Google and founded their own AI start-ups (except Łukasz Kaiser, who joined OpenAI ). For many years, sequence modelling and generation

13572-430: Was revamped to Google Neural Machine Translation , which replaced the previous model based on statistical machine translation . The new model was a seq2seq model where the encoder and the decoder were both 8 layers of bidirectional LSTM. It took nine months to develop, and it outperformed the statistical approach, which took ten years to develop. Seq2seq models with attention (including self-attention) still suffered from

13689-462: Was steadfast in its not-yet-popular belief that science could only move forward through a transparent and open exchange of ideas backed by experimental evidence. Early scientific journals embraced several models: some were run by a single individual who exerted editorial control over the contents, often simply publishing extracts from colleagues' letters, while others employed a group decision-making process, more closely aligned to modern peer review.
