CNTK

CNTK is a deep learning toolkit used for the design, construction, and training of neural networks. It defines model architectures as computational graphs and optimizes network parameters using an automatic differentiation engine and stochastic gradient descent.

The project emphasizes large scale model distribution, spreading training workloads across multiple hardware nodes and GPUs. It features specialized support for dynamic sequence handling, allowing filters to be convolved across both spatial and dynamic sequence axes to process data of variable lengths.

The toolkit provides hardware-accelerated tensor kernels and optimized CPU inference for floating-point math. It includes a variety of deep learning operations such as grouped convolutions and exponential linear unit activations, as well as tools for execution performance profiling.

Model interoperability is handled through the Open Neural Network Exchange specification, which allows the export and exchange of models across different deep learning runtimes.
