โ€‹โ€‹XLNet: Generalized Autoregressive Pretraining for Language Understanding

Researchers at Google Brain and Carnegie Mellon introduce #XLNet, a pre-training algorithm for natural language processing systems. It helps NLP models (in this case, based on Transformer-XL) achieve state-of-the-art results in 18 diverse language-understanding tasks including question answering and sentiment analysis.

โ€‹โ€‹Using Deep Learning to Inform Differential Diagnoses of Skin Diseases

Deep Learning System (DLS) for quicker and cheaper skin diseases detection. DLS showed accuracy across 26 skin conditions on par with U.S. board-certified dermatologists, when presented with identical information about a patient case (images and metadata). This is an amazing example of how technology can help fight notoriously high medical bills in the USA and make top-level care available and more affordable in all other the world.

Large-Scale Multilingual Speech Recognition with a Streaming End-to-End Model

High-quality #speechrecognition systems require large amounts of dataโ€”yet many languages have little data available. Check out new research into an end-to-end system trained as a single model allowing for real-time multilingual speech recognition.

โ€‹โ€‹๐Ÿ”ฅDeepMindโ€™s AlphaStar beats top human players at strategy game StarCraft II

AlphaStar by Googleโ€™s DeepMind can now play StarCraft 2 so well that it places in the 99.8 percentile on the European server. In other words, way better than even great human players, achieving performance similar to gods of StarCraft.

Solution basically combines reinforcement learning with a quality-diversity algorithm, which is similar to an evolutionary algorithm.

Whatโ€™s difficult about StarCraft and how is it different to recent #Go and #Chess AI solutions: even finding winning strategy (StarCraft is famouse to closeness to rock-scissors-paper, not-so-transitive game design, as chess and go), is not enough to win, since the result depends on execution on different macro and micro levels at different timescales.

How that is applicable in real world: basically, it is running logistics, manufacture, research with complex operations and different units.

Why this matters: it brings AI one step closer to running real business.

๐Ÿ”ฅHuman-like chatbots from Google: Towards a Human-like Open-Domain Chatbot.

TLDR: humanity is one huge step closer to a chat-bot, which can chat about anything and has great chance of success, passing #TuringTest

What does it mean: As an example, soon you will have to be extra-cautious chatting in #dating apps, because there will be more chat-bots, who can seem humane.
This also means that there will some positive and productive applications too: more sophisticated selling operators, on-demand psychological support, you name it.

It might be surprising, but #seq2seq still works. Over 5+ years of working on neural conversational models, general progress is a fine-tune of basic approach. It is a proof that much can be still discovered, along with room for new completely different approaches.

โ€‹โ€‹AutoFlip: An Open Source Framework for Intelligent Video Reframing

Google released a tool for smart video cropping. Video cropping doesn't seem like a poblem until you release that object that should be in focus can be in different parts of picture. Now there is great attempt to provide one-click solution to cropping.

Interesting part: #AutoFlip is an application of #MediaPipe framework for building multimodal ML #pipelines.

โ€‹โ€‹Racial Disparities in Automated Speech Recognition

Lo-Fi Player

The team from the magenta project, that does research about deep learning and music powered by TensorFlow in Google, obviously, release a new fun project lofi-player powered by their open-source library magenta.js.

So it's basically a lo-fi music generator which popular genre on youtube streams and other kinds of stuff. You can customize the vibe on your manner and wish from sad to moody, slow to fast, etc.

It is based on their earlier work MusicVae to sample latent space of music and MelodyRNN to generate music sequences from different instruments. The project is not about new research, but to show what can do with an already done library in a creative way.

They also create a stream on youtube to listen lo-fi generated by that application and users in chat can together tune lo-fi player in stream :)

Imagen โ€” new neural network for picture generation from Google

TLDR: Competitor of DALLE was released.

Imagen โ€” text-to-image diffusion model with an unprecedented degree of photorealism and a deep level of language understanding. Imagen builds on the power of large transformer language models in understanding text and hinges on the strength of diffusion models in high-fidelity image generation. #Google key discovery is that generic large language models (e.g. T5), pretrained on text-only corpora, are surprisingly effective at encoding text for image synthesis: increasing the size of the language model in Imagen boosts both sample fidelity and image-text alignment much more than increasing the size of the image diffusion model.
