User Reviews

  • Great library for all its use cases.

  • Great set of C++ libraries, including deep learning. Excellent examples get you started quickly.

  • The best machine learning library for C++ !!

  • the library is very useful for me researcher and student.

  • It's a bloody good C++ library for machine learning, but I would use it even just for file/folder handling. The code is properly designed, tested and documented. The author is very helpful and answers to most questions within hours or days.
