Perceptron: AI that sees with sound, learns to walk and predicts seismic physics

Research in the field of machine learning and AI, now a key technology in practically every industry and company, is far too voluminous for anyone to read it all. This column, Perceptron, aims to collect some of the most relevant recent discoveries and papers -- particularly in, but not limited to, artificial intelligence -- and explain why they matter. This month, engineers at Meta detailed two recent innovations from the depths of the company's research labs: an AI system that compresses audio files and an algorithm that can accelerate protein-folding AI performance by 60x. Elsewhere, scientists at MIT revealed that they're using spatial acoustic information to help machines better envision their environments, simulating how a listener would hear a sound from any point in a room. Meta's compression work doesn't exactly reach unexplored territory. Last year, Google announced Lyra, a neural audio codec trained to compress low-bitrate speech.
