Hello. Are there any machine learning libraries in C#? I'm after something like WEKA. Thank you.
There's a neural network library called AForge.net on the codeproject. (Code hosted at Google code) (Also checkout the AForge homepage - According to the homepage, the new version now supports genetic algorithms and machine learning as well. It looks like it's progressed a lot since I last played with it)
I don't know it's it's anything like WEKA as I've never used that.
(there's also an article on it's usage)
You can also use Weka with C#. The best solution is to use IKVM, as in this tutorial, although you can also use bridging software.
Apart from AForge.NET there is also Accord.NET, which is an extension framework to AForge. Accord.NET implements many other machine learning techniques such as support vector machines, hidden Markov models and other statistical analysis, while also focusing on ease of use.
