Bright Wire is an extensible machine learning library for .NET with GPU support (via CUDA).

Getting Started

Bright Wire is a .net 6 class library.

The previous .net 4.6 version can be found here: https://github.com/jdermody/brightwire-v2

Bright Wire runs "out of the box" for CPU based computation. For GPU based computation, you will need to install NVIDIA CUDA Toolkit 11 (and have a Kepler or better NVIDIA GPU).

To enable higher performance CPU based computation, Bright Wire also supports the Intel Math Kernel Library (MKL) via the Numerics.Net Wrapper.
