TITLE: Fast and Scalable Deep Learning with Microsoft Cognitive Toolkit (CNTK)

CNTK is Microsoft's open-source deep learning framework designed from the ground up for scalability and flexibility. The latest v2.0 release contains both C++ and Python APIs, with a built-in Layer Library for high-level model description. The toolkit has been extensively used internally at Microsoft for video, image, text and speech data. CNTK is well-regarded as the fastest toolkit for recurrent neural networks, which can easily be 5-10x faster than other toolkits such as TensorFlow and Torch. It was the key to Microsoft Research’s recent breakthrough in speech recognition by reaching human parity in conversational speech recognition. In this talk, I will explain how CNTK achieves significant speed up through symbolic loops, sequence batching, and new schemes of data-parallel training.
