Tax Relief the AI Way: AI Economist creates optimal tax rate.
Nothing is certain except death and taxes, the saying goes — but how to make taxes fair and beneficial remains an open question. New research aims to answer it.

Wolfram Burgard: Train robots in the real world
Robots are tremendously useful machines, and I would like to see them applied to every task where they can do some good. Yet we don’t have enough programmers for all this hardware and all these tasks.

Reinforcement Learning Transformed: Transformers succeed at reinforcemend learning tasks.
Transformers have matched or exceeded earlier architectures in language modeling and image classification. New work shows they can achieve state-of-the-art results in some reinforcement learning tasks as well.

Finding Useful Points in Space: Keypoint3D Helps Robots Locate Spatial Coordinates
A new machine learning method aims to improve a machine’s ability to determine and locate points of interest.

Different Strokes for Robot Folks: Transformer-Based Image Generator Imitates Painters
A neural network can make a photo resemble a painting via neural style transfer, but it can also learn to reproduce an image by applying brush strokes. A new method taught a system this painterly skill without any training data.

Who Needs a Covid Test? AI Decides: Greek Border Patrol Used AI to Screen for Covid
Greece’s border agents last year had enough Covid tests to swab only 17 percent of people who sought to enter the country. They managed the shortage by using an AI system to flag high-risk visitors.

Team Players: Football-Playing AI Blends Individual and Group Skills
Playing a team sport involves a fluid blend of individual and group skills. Researchers integrated both types of action into realistic humanoid agents that play football (known as soccer in the U.S.).

Weak Foundations Make Weak Models: Foundation AI Models Pass Flaws to Fine-Tuned Variants
A new study examines a major strain of recent research: huge models pretrained on immense quantities of uncurated, unlabeled data and then fine-tuned on a smaller, curated corpus.

Solve RL With This One Weird Trick: How to get better performance from reinforcement learning.
The previous state-of-the-art model for playing vintage Atari games took advantage of a number of advances in reinforcement learning (RL). The new champion is a basic RL architecture plus a trick borrowed from image generation.

Bye Bye Bots: OpenAI quit robotics to focus on AGI.
The independent research lab OpenAI wowed technology watchers in 2019 with a robotic hand that solved Rubik’s Cube. Now it has disbanded the team that built it. OpenAI cofounder Wojciech Zaremba revealed that OpenAI shuttered its robotics program last October.

Walking the Dog: Training a robot to walk over unsteady terrain with RL.
A reinforcement learning system enabled a four-legged robot to amble over unfamiliar, rapidly changing terrain.

Behavioral Cloning Shootout: AI learns to play Counter Strike Global Offensive.
Neural networks have learned to play video games like Dota 2 via reinforcement learning by playing for the equivalent of thousands of years (compressed into far less time). In new work, an automated player learned not by playing for millennia but by watching a few days’ worth of recorded gameplay.
