CNTK (Microsoft Cognitive Toolkit) is an open-source deep learning framework developed by Microsoft. It describes neural networks as directed graphs, supports multi-GPU and multi-machine training, and provides Python, C++, and C# APIs. It started from speech recognition research; active development has since stopped, and PyTorch or ML.NET, among others, are recommended for new projects.
