Welcome to Perceptron, TechCrunch's weekly roundup of AI news and research from around the world. Machine learning is a key technology in practically every industry now, and there's far too much happening for anyone to keep up with it all. This column aims to collect some of the most interesting recent discoveries and papers in the field of artificial intelligence -- and explain why they matter. This week's roundup starts with a pair of forward-thinking studies from Facebook/Meta. The first is a collaboration with the University of Illinois at Urbana-Champaign that aims at reducing the amount of emissions from concrete production. Concrete accounts for some 8 percent of carbon emissions, so even a small improvement could help us meet climate goals.

In this DZone Refcard, learn about TensorFlow, an open-source library with a rich set of application programming interfaces for most major languages and environments needed for deep learning programs like sentiment analysis and object detection.
