# TensorStream
A reimplementation of TensorFlow for ruby. This is a ground up implementation with no dependency on TensorFlow. Effort has been made to make the programming style as near to TensorFlow as possible, comes with a pure ruby evaluator by default as well with support for an opencl evaluator.
The goal of this gem is to have a high performance machine learning and compute solution for ruby with support for a wide range of hardware and software configuration.

+You can take a look at spec/tensor_stream/operation_spec.rb for a list of supported ops and various examples and test cases used. Of course these contain only a
+sliver of what TensorFlow can do, so feel free to file a PR to add requested
+ops and test cases.

Not all ops are available. Available ops are defined in lib/tensor_stream/ops.rb, corresponding gradients are found at lib/tensor_stream/math_gradients.
There are also certain differences with regards to naming conventions, and named parameters:
