🦜 Hi!

We are the first Telegram Data Science channel.

Channel was started as a collection of notable papers, news and releases shared for the members of Open Data Science (ODS) community. Through the years of just keeping the thing going we grew to an independent online Media supporting principles of Free and Open access to the information related to Data Science.

Highly accurate protein structure prediction with AlphaFold
Anna Potapenko @DeepMind

Predicting a protein’s structure from its primary sequence has been a grand challenge in biology for the past 50 years, holding the promise to bridge the gap between the pace of genomics discovery and resulting structural characterization. In this talk, we will describe work at DeepMind to develop AlphaFold, a new deep learning-based system for structure prediction that achieves high accuracy across a wide range of targets. We demonstrated our system in the 14th biennial Critical Assessment of Protein Structure Prediction (CASP14) across a wide range of difficult targets, where the assessors judged our predictions to be at an accuracy “competitive with experiment” for approximately 2/3rds of proteins. The talk will cover both the underlying machine learning ideas and the implications for biological research.

Using public datasets in commercial software

Great paper: Can I use this publicly available dataset to build commercial AI software? Most likely not.

An extremely important question for the Data Science community: it turns out (wat?) that not all publicly available datasets can be used to build commercial solutions 💣💣💣.

Authors examine license agreements of 6 popular datasets used in Computer Vision (CIFAR-10, ImageNet, Cityscapes, FFHQ, VGGFaces2 and MS COCO) and conclude that the models trained on these data can not be commercialized at least.

An example of the results of the CIFAR-10 dataset's license analysis is shown in the screenshot.

It was logical to assume this, but for many community members this may be the opening of the century.

​​There had been less posts than usual as you might have noticed, only because editor-in-chief's (mine) attention been directed to DeFi space in general and NFT in particular.

However once involved with the beauty of AI and art, one can't just exit it, so I've been working on an NFT-collection drop as an exercise to study the field. Because as Feynman taught us 'What I cannot create, I do not understand'.

After getting some early results with #StyleGAN2 I realised that I need to study how drop mechanics and everything else works and asked a very talented friend to help me with generating the art for the collection. On my humble scale, he is top 0.1% researcher in the field (though he might argue with that, or you might, but let's wait for his scientific papers published here to judge on that), so I was sure that the art will be dope.

And it was so great we decided to make a real NFT drop instead of purely experimental one. Soon we will publish all the intersting technical details on the architecture and approache we used to generate beautiful toadz. So stay tuned for the post on how to generate astonishing art and subsribe to the collection twitter not to miss any details.

AIModel-Mutator: Finding Vulnerabilities in TensorFlow

Another current study on the security of machine learning models, and information on how framework bugs (such as Tensorflow) can affect it. For example, from 2019 to 2021, the number of CVEs for TF increased 15 times.

Qian Feng, a senior security researcher at Baidu Security talks about the important work they did with their colleagues.

As we know, it's pretty easy to corrupt models, they freely distributed and without any additional checks, so short deep dive into the problem in this video: https://www.youtube.com/watch?v=7QqbJRZ6CxU.

​​Simple book about #ML — Machine Learning Simplified

The main purpose of the book is to build an intuitive understanding of how algorithms work through basic examples. In order to understand the presented material, it is enough to know basic mathematics and linear algebra.

After reading this book, you will know the basics of supervised learning, understand complex mathematical models, understand the entire pipeline of a typical ML project, and also be able to share your knowledge with colleagues from related industries and with technical professionals.

And for those who find the theoretical part not enough - the book is supplemented with a repository on GitHub, which has Python implementation of all methods and algorithms described in chapters.

Book is absolutely free to read.

AlphaCode Explained: AI Code Generation

AlphaCode is DeepMind's new massive language model for generating code. It is similar to OpenAI Codex, except for in the paper they provide a bit more analysis. The field of NLP within AI and ML has exploded get a lot more papers all the time. This video can help you understand how AlphaCode works and what some of the key takeaways are.

How Useful is Self-Supervised Pretraining for Visual Tasks?

A relatively old paper (CVPR2020), by our fast life standards. Nevertheless, it has a pair of practical takeaways.

Authors created a synthetic dataset with several degrees of freedom to vary difficulty. It varies from almost monochrome objects to randomized textures and positioning on image.

The target was to compare how good different self-supervised approaches help to tune for different downstream tasks. From classification to depth estimation.

Two practical takeways are:
1. The self-supervised method utility is wildly dependent on task, markup amount and even data complexity.
2. A linear evaluation score, so popular in papers, has almost no correlation with actual fine-tuning results.

Authors found out, that there is no improvement by self-supervised training when lots of labeled data presented (which became kinda well known since then). Based on this, they hypothesise, that improvement of SSL pre-training is rather kind of a regularization than optimization. That is, SSL pre-training helps to find wider optimum, not better. Though, to claim this, some kind of loss plane investigation would be more helpful.

Models based on graphs are quite important for a lot of tasks in NLP. There is an overview from Michael Bronstein about what he is expecting for upcoming year for the Graph ML field:

1. Geometry becomes increasingly important in ML.
2. Message passing is still the dominant paradigm in GNNs.
3. Differential equations give rise to new GNN architectures.
4. Old ideas from Signal Processing, Neuroscience, and Physics get a new life.
5. Modeling complex systems requires going beyond graphs.
6. Reasoning, axiomatisation, and generalisation are still big open questions in Graph ML.
7. Graphs become increasingly popular in Reinforcement Learning, but probably still have a way to go.
8. AlphaFold 2 is a triumph of Geometric ML and a paradigm shift in structural biology.
9. Drug discovery and design benefits from GNNs and their confluence with Transformers.
10. AI-first drug discovery is increasingly using Geometric and Graph ML.
11. Quantum ML benefits from graph-based methods.

Deep Neural Nets: 33 years ago and 33 years from now

Great post by Andrej Karpathy on the progress #CV made in 33 years.

Author's ideas on what would a time traveler from 2055 think about the performance of current networks:

* 2055 neural nets are basically the same as 2022 neural nets on the macro level, except bigger.
* Our datasets and models today look like a joke. Both are somewhere around 10,000,000X larger.
* One can train 2022 state of the art models in ~1 minute by training naively on their personal computing device as a weekend fun project.
* Today’s models are not optimally formulated, and just changing some of the details of the model, loss function, augmentation or the optimizer we can about halve the error.
* Our datasets are too small, and modest gains would come from scaling up the dataset alone.
* Further gains are actually not possible without expanding the computing infrastructure and investing into some R&D on effectively training models on that scale.
