Accord.NET
Accord.NET combines machine learning with audio and image processing libraries in a C# framework.
About Accord.NET
Accord.NET is a .NET machine learning framework combined with audio and image processing libraries. It is written in C# and is intended for building computer vision, computer audition, signal processing, and statistics applications. The site states it can be used in commercial applications.
With the framework, you can work on classification tasks using methods such as support vector machines, logistic regression, decision trees, and neural networks. It also covers regression, clustering, statistical distributions, hypothesis tests, and kernel methods. For imaging and audio, it includes feature detectors, image filters, audio loading and filtering, signal transforms, and face detection and tracking in image streams.
Accord.NET suits C# and .NET developers who need machine learning, vision, audio, or statistics functions in their projects. Sample applications, documentation, and a wiki are provided to help users get started and find implementation details.
