Are there any machine learning libraries in C#? I'm after something like WEKA.

Hi Emma, Mlpack is a fast, flexible machine learning library, written in C++. The library aims to provide fast, extensible implementations of cutting-edge machine learning algorithms.

Yes, there are machine learning libraries in c#. C# is one of the most versatile programming languages in the world. It allows developers to build all kinds of applications including Windows clients, consoles, Web apps, mobile apps, and backend systems. C# can be used for machine learning applications via a. NET Core machine learning platform, ML.NE.
