Facebook open-sources Caffe2, a new deep learning framework

At its F8 developer conference in San Jose today, Facebook is announcing the launch of Caffe2, a new open source framework for deep learning, a trendy type of artificial intelligence (AI). Deep learning generally involves training artificial neural networks on lots of data, like photos, and then getting them to make inferences about new data. Today's announcement builds on Facebook's contributions to the Torch open source deep learning framework and more recently the PyTorch framework that the Facebook Artificial Intelligence Research (FAIR) group conceived. And last year Facebook talked about a system called Caffe2go. "PyTorch is great for research, experimentation and trying out exotic neural networks, while Caffe2 is headed towards supporting more industrial-strength applications with a heavy focus on mobile," Facebook AI Platform engineering lead Yangqing Jia wrote in a comment on Hacker News.
