Bindings for CNTK library

Simple low level bindings for CNTK library from Microsoft.

Status

Currently exploring ways how to interact with C++ API nicely from Rust. Expect a lot of breaking changes.

Build scripts are not ready yet, might not work outside of 64bit linux.

Building and installing

You need to have CNTK-2.2 installed and paths to includes and library files in relevant enviroment variables (cntk activate scripts does this well). You also need g++-4.8 installed (because CNTK uses it to compile things).

Other limitations

Only works with single precision (f32 in Rust, float in C++) types. Only works with dense representations of vectors/matrices/tensors. Only works with ASCII strings for variable names and filenames.

Roadmap

• Figure out how to pass data in and out. Currently Value::batch for input and Value::to_vec should be enough.
• Variable creation. - Some basics are there
• Gradients. - Possible to do backward pass
• Training simple feed forward net. - Possible.
• Save and load model. - Possible.
• Training recurrent or seq2seq net. - Recurrences are possible.
• Convnets. - Convolution and pooling are present
• Code for most operations. (probably generated). - Almost all, except couple of helpers.
• Write some meaningful examples. - Only in tests now.
• Catch all relevant C++ exceptions
• Better build scripts.
