Google launches open source machine-learning system TensorFlow

Google has built and launched a new machine-learning system called TensorFlow, making it available for any developer through a an online open source library. Google’s existing machine-learning infrastructure, known as DistBelief, has hitherto been used internally at Google, for example to identify and automatically label items contained with YouTube videos and photos, as well as improve speech recognition in Google apps. But, according to Google, DistBelief was limited, insofar as it was “narrowly targeted to neural networks, it was difficult to configure, and it was tightly coupled to Google’s internal infrastructure — making it nearly impossible to share research code externally,” according to a blog post by Jeff Dean, senior Google fellow, and Rajat Monga, Technical Lead. TensorFlow is basically a second-generation machine-learning system, one that Google claims is twice…
