Scalable digital fitting room based on the first full-body Deepfake

The next generation of Deepfake does the full-body swap including head, hair, skin tone and body shape modification. Practically the new technology aims to be applied for a brand agnostic digital fitting room, that works on the existing content and doesn't require content creation on the brand side.

To demonstrate other applications and raise interest of the community, developer created a video, demonstrating many features of the new generation of Deepfake.

​​learning to summarize from human feedback
by openai

the authors collect a high-quality dataset of human comparisons between summaries, train a model to predict the human-preferred summary & use that model as a reward function to fine-tune a summarization policy using reinforcement learning. they apply this method to a version of the tl;dr dataset of reddit posts & find that their models significantly outperform both human reference summaries & much larger models fine-tuned with supervised learning alone

the researchers focused on english text summarization, as it’s a challenging problem where the notion of what makes a "good summary" is difficult to capture without human input

these models also transfer to cnn/dm news articles, producing summaries nearly as good as the human reference without any news-specific fine-tuning. furthermore, they conduct extensive analyses to understand the human feedback dataset & fine-tuned models. they establish that their reward model generalizes to a new dataset & that optimizing their reward model results in better summaries than optimizing rouge according to humans

​​NVidia released a technology to change face alignment on video

Nvidia has unveiled AI face-alignment that means you're always looking at the camera during video calls. Its new Maxine platform uses GANs to reconstruct the unseen parts of your head — just like a deepfake.

- PEP 584, Union Operators in dict
- PEP 585, Type Hinting Generics In Standard Collections
- PEP 593, Flexible function and variable annotations
- PEP 602, Python adopts a stable annual release cadence
- PEP 614, Relaxing Grammar Restrictions On Decorators
- PEP 615, Support for the IANA Time Zone Database in the Standard Library
- PEP 616, String methods to remove prefixes and suffixes
- PEP 617, New PEG parser for CPython
- BPO 38379, garbage collection does not block on resurrected objects;
- BPO 38692, os.pidfd_open added that allows process management without races and signals;
- BPO 39926, Unicode support updated to version 13.0.0;
- BPO 1635741, when Python is initialized multiple times in the same process, it does not leak memory anymore;
- A number of Python builtins (range, tuple, set, frozenset, list, dict) are now sped up using PEP 590 vectorcall;
- A number of Python modules (_abc, audioop, _bz2, _codecs, _contextvars, _crypt, _functools, _json, _locale, operator, resource, time, _weakref) now use multiphase initialization as defined by PEP 489;
- A number of standard library modules (audioop, ast, grp, _hashlib, pwd, _posixsubprocess, random, select, struct, termios, zlib) are now using the stable ABI defined by PEP 384.

#python, #release

PEP 584 — new operator "|" that can be used to merge two dictionaries

PEP 584 — another new operator "|=" will let you update dictionaries.

Open cool NOT Kaggle contest – AIJ Contest 2020 🎉

◼️ Digital Peter: Recognition of Peter the Great’s manuscripts
October 9 – November 8
Digital Peter is an educational task with a historical slant created on the basis of several AI technologies (CV, NLP, and knowledge graphs). The task was prepared jointly with the Saint Petersburg Institute of History of the Russian Academy of Sciences, Federal Archival Agency of Russia and the Russian State Archive of Ancient Acts.
Participants are invited to create an algorithm for line-by-line recognition of manuscripts written by Peter the Great.

◼️ NoFloodWithAI: Flash floods on the Amur river
October 9 – November 1
NoFloodWithAI is a special track with a socially important theme prepared jointly with the Ministry of Emergency Situations, Ministry of Natural Resources and Rosgidromet of Russia.
Participants are invited to develop an algorithm for short-term forecasting of water levels in the Amur River for the following settlements: Dzhalinda, Blagoveshchensk, Innokentievka, Leninskoye, Khabarovsk, Komsomolsk-on-Amur, Nikolaevsk-on-Amur for 10 days in advance in order to prevent emergency situations in Russia’s regions. The results of the contest will be reused to mitigate environmental risks and minimize economic damage wrought on the regions.


◼️ AI4Humanities: ruGPT-3
October 16 – November 1
It is a track developed especially for those familiar with artificial neural networks. It will help to learn about a promising ruGPT-3 technology able to generate very complex meaningful texts based on just one request made in natural human language. For example, it can help you answer most questions included in basic or unified national exams (OGE or EGE), write Java code at the request "Please make a website for the online shop", come up with a business idea for a new startup, or write new popular science articles.

> How to make CPython faster.

> We want to speed up CPython by a factor of 5 over the next four releases.
> See the plan for how this can be done.
> Making CPython faster by this amount will require funding. Relying on the goodwill and spare time of the core developers is not sufficient.

This includes JIT and other awesome features for #python
