​​Memory Transformer
Burtsev & Sapunov

The authors proposed and studied two memory augmented architectures MemTransformer and MemBottleneck Transformer. Qualitative analysis of attention patterns produced by the transformer heads trained to solve machine translation task suggests that both models successfully discovered basic operations for memory control. Attention maps show evidence for the presence of memory read/write as well as some in-memory processing operations such as copying and summation.

A comparison of machine translation quality shows that adding general-purpose memory in MemTransformer improves performance over the baseline. Moreover, the speed of training and final quality positively correlates with the memory size. On the other hand, MemBottleneck Transformer, with all self-attention restricted to the memory only, has significantly lower scores after training.

Memory lesion tests demonstrate that the performance of the pre-trained MemTransformer model critically depends on the presence of memory. Still, the memory controller learned by the model degrades only gradually when memory size is changed during inference. This indicates that the controller has some robustness and ability for generalization.

​​πŸ”₯Logo generation autonomous system was revealed to be used in production for almost a year.

Leading Russia-based design studio Artlebedev revealed that they experimented with using neural networks and set of algorithmic systems to design logotypes for real customers. They named system Nikolay Ironov (in russian N.Ironov sounds close to Neuronov). The system realeased 17 commercial projects, which were welcomed by the audience.

Mishief managed! 😈

​​Pre-training via Paraphrasing
Mike Lewis, Marjan Ghazvininejad & etc. by Facebook AI

The authors introduce MARGE, a pre-trained seq2seq model learned with an unsupervised multi-lingual multi-document paraphrasing objective.
MARGE provides an alternative to the dominant masked language modeling paradigm, where they self-supervise the reconstruction of target text by retrieving a set of related texts (in many languages) and conditioning on them to maximize the likelihood of generating the original. Showed it is possible to jointly learn to do retrieval and reconstruction, given only a random initialization.
The objective noisily captures aspects of paraphrase, translation, multi-document summarization, and information retrieval, allowing for strong zero-shot performance on several tasks. For example, with no additional task-specific training they achieve BLEU scores of up to 35.8 for document translation.
Further show that fine-tuning gives a strong performance on a range of discriminative and generative tasks in many languages, making MARGE the most generally applicable pre-training method to date.
Future work should scale MARGE to more domains and languages, and study how to more closely align pre-training objectives with different end tasks.

​​(Re)Discovering Protein Structure and Function Through Language Modeling

Trained solely on unsupervised language modeling, the Transformer's attention mechanism recovers high-level structural (folding) and functional properties of proteins!

Why this is important: traditional protein modelling requires lots of computational power. This might be a key to more efficient structure modelling. Protein structure => function. Function => faster drug research and understanding of diseases mechanisms.

β€‹β€‹πŸŽ™Mozilla’s Common Voice project

Mozilla launched a project to make digitalization of human voice more open and accessable. Anyone is eligible to download the dataset to use it for building #voicerecognition or #voicegeneration ML systems.

Most importantly, anyone can take a part in the project and make sure that her/his voice with all the accents and personal manner of speech features such as altitude, speed, clarity and timbre are accounted for in the models are to built.

Why is that important: if you have speech defects and you are not happy how machine speech translation works for you, or how well #Alexa or #Siri gets you, you should spend some time recording your voice for the Common Voice, to increase the probability of upcoming voice recognition model working great for you.

​​ReXNet: Diminishing Representational Bottleneck on Convolutional Neural Network

The authors propose a set of design principles that improves model performance significantly based on the analysis of representation bottlenecks.

Authors think that commonly used architectures have a representation bottleneck and try to fix it by expanding channel size, using more expand layers, and better activation functions. This also improves the performance of models on ImageNet and good results on transfer learning on classification and object detection.
Authors hope that their design ideas could be used by NAS to create even better models.

Soon we will give a try to certain solution which will allow commenting on the posts in this channel.

Therefore, we will at first release the Ultimate Post on #wheretostart with Data Science, describing various entry points, books and courses. We want to provide extensive and thorough manual (just check out the name we chose), so we would be grateful if you can submit any resourses on getting starting with DS (any sphere) through our bot @opendatasciencebot (make sure you add your username, so we can reach you back)

You are most welcome to share:

​​A new SOTA on voice separation model that distinguishes multiple speakers simultaneously

Pandemic given a sufficient rise to new technologies covering voice communication. Noise cancelling is required more than ever and now #Facebook introduced a new method for separating as many as five voices speaking simultaneously into a single microphone. It pushes state of the art on multiple benchmarks, including ones with challenging noise and reverberations.

​​Ultimate post on where to start learning DS

Most common request we received through the years was to share insights and advices on how to start career in data science and to recommend decent cources. Apparently, using hashtag #wheretostart wasn't enough so we were sharing some general advices.

So we assembled a through guide on how to start learning machine learning and created another #ultimatepost (in a form of a github repo, so it will be keep updated and anyone can submit worthy piece of advice to it).

We welcome you to share your stories and advices on how to start rolling into data science, as well as to spread the link to the repo to those your friends who might benefit from it.

​​GPT-3 application for website form generation

Turns out #GPT3 model is capable of generating #JSX code (which is HTML layout for #React ) given the description of the required blocks to generate.

Author reports that there are exceptions, given current output limit of the model of 512 tokens.

Why this is important: one might suppose that in the future programmers will just write specifications and tests for the AI to generate the code. Given the speed of progress that won’t be surprising at all.

And probably the more sophisticated models will be capable of using hard output limit to produce a code for the output generation but that obviously is still an area for active research.

More realistic evaluation is that the upcoming code generation tools is that it will just allow more people to build products, following #nocode movement.

​​Voila turns Jupyter notebooks into standalone web applications.

Unlike the usual HTML converted notebooks, each user connecting to the Voila tornado application gets a dedicated Jupyter kernel which can execute the callbacks to changes in Jupyter interactive widgets.

- By default, Voila disallows execute requests from the front-end, preventing execution of arbitrary code.
- By default, Voila runs with the strip_source option, which strips out the input cells from the rendered notebook.

The Reformer – Pushing the limits of language modeling
Patrick von Platen @ huggingface

The Reformer model was introduced by Kitaev, Kaiser et al. `20 – it is one of the most memory-efficient transformer models for long sequence modeling as of today.

The goal of this blog post is to give an in-depth understanding of each of the next four Reformer features:
[0] reformer self-attention layer – how to efficiently implement self-attention without being restricted to a local context?
[1] chunked feed forward layers – how to get a better time-memory trade-off for large feed forward layers?
[2] reversible residual layers – how to drastically reduce memory consumption in training by a smart residual architecture?
[3] axial positional encodings – how to make positional encodings usable for extremely large input sequences?

This long blog post can better allow you to understand how the model works to correctly set configurations
