About FCNN

FCNN (Fast Compressed Neural Networks) is a free open source C++ library for Artificial Neural Network computations. It is easy to use and extend, written in modern C++ and is very fast (to author's best knowledge it is the fastest freely available neural network library). All FCNN classes are templated to support both single and double precision computations. Main features are listed under Features tab. Internal representation of network in FCNN differs from all other libraries allowing true code modularisation with simultaneous speed improvements. In order to further improve the speed of computations FCNN employs BLAS and OpenMP. FCNN implementation strategy is described in this paper.

About current release (0.5.1, released March 6, 2016)

This is a patched version of the 0.5.0 release. FCNN now supports different activation functions at each layer. New MLPNet member functions allow input neurons to be removed, added and reordered. Matrix class has two new members: get_rows and get_cols. Stochastic gradient descend teaching algorithm is now provided. Please refer to the NEWS and Changelog files distributed along with the source code.

R interface

Package FCNN4R providing R interface to FCNN kernel routines is available on CRAN.
