Microsoft this week released an updated version of its Microsoft Cognitive Toolkit as an open source Beta. The deep learning system is used to speed advances in areas such as speech and image recognition and search relevance on CPUs and Nvidia GPUs. It also works with Microsoft’s Azure GPU offering. The Microsoft computer scientists who developed the toolkit initially were looking for a tool to speed up and improve their own research. It morphed into an offering capable of taking on a wide variety of deep learning tasks.
