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

Getting Started

Bright Wire is a .net 8 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" with its own vectorised linear algebra library.

If you have a NVIDIA GPU then you can also use GPU based computation. You will need to install NVIDIA CUDA Toolkit 12 (and have a Kepler or better NVIDIA GPU).

To enable higher performance CPU based computation on Intel hardware, Bright Wire also supports the Intel Math Kernel Library (MKL).

Tutorials

Nuget Installation

To install the cpu version (no CUDA support) use:

Install-Package BrightWire

To add MKL support use:

Install-Package BrightWire
Install-Package BrightData.MKL

To add CUDA support use:

Install-Package BrightWire
Install-Package BrightData.Cuda
