🔥Out of One, Many: Using Language Models to Simulate Human Samples

TLDR: GPT-3 has unexpected application — modelling of socialogical studies. Average responses of a certain groups can be to some algorithmical accuracy predicted by in silico modelling.

What this means: sociologists won’t have to conduct costly live researches and will be able to run experiments in simulations. Marketers and politicians are getting their hands on cheap solution for modelling their slogans and value propositions. This enables people to check more hypothesis faster and to manipulate society with more efficiency.

CORL: Offline Reinforcement Learning Library

Offline RL is a fresh paradigm that makes RL similar to the supervised learning, thus making it better applicable to the real-world problems. There is a whole bunch of recently developed Offline RL aglorithms, however, there was nots many of reliable open-sourced implementations for such algorithms

Our friends from @tinkoffai do some research in this direction and they recently open-sourced their internal offline RL library.

The main features are:
- Single-file implementations
- SOTA algorithms (Decision Transformer, AWAC, BC, CQL, IQL, TD3+BC, SAC-N, EDAC)
- Benchmarked on widely used D4RL datasets (results match performances reported in the original papers)
- Wandb logs for all of the experiments

Hope you will like it and the whole new world of Offline RL!

Amos: An Adam-style Optimizer with Adaptive Weight Decay towards Model-Oriented Scale

Amos is a new optimizer that we propose to pre-train large language models. It is more efficient and converges faster than AdamW: ≤ 51% memory for slot variables, and better valid loss within ≤ 70% training time!Amos is a new optimizer that we propose to pre-train large language models.

Tips & Tricks on Image Generation

Generating images with AI tools is a skill, which can be improved and enhanced. So here is couple of articles, covering tips & tricks on how to generate better images with #midjourney. Most interesting one is #huggingface prompt generator, which uses #NLP model to generate sample prompts.

As an example, we tried to reproduce and improve our group avatar, following ideas in the articles. Prompt for an illustration to this post was generated with query ferrofluids in form of a brain, beautiful connections chaos, swirling black network --ar 3:4 --iw 9 --q 2 --s 1250

ML track at YaTalks 2022

YaTalks, Yandex’s main conference for the IT community, will be held on December 3 and 4. More than 100 tech experts from around the globe will gather to discuss technology and life in today’s ever-changing world. In the program, there are tracks about backend, frontend, mobile development, and, of course, machine learning.

Speakers will discuss:
• what significant events have happened in the sphere of machine learning for the last 10 years;
• how neural network-driven translation works;
• how generative neural networks create pictures and whether they are able to replace illustrators;
• and many other topical issues.

This year YaTalks will be streamed simultaneously in two languages — Russian and English — using neural network-driven voice-over translation technologies. The conference is online, so you can join it from anywhere in the world.

There is a claim that #ChatGPT is capable of writing a code based on a text input

Why does it matter: it potentially can lower the barrier for programmers and allow more tools for efficient software development to emerge.
