MBP: Matrix Backpropagation Package

areas/neural/systems/mbp/

MBP (Matrix Back Propagation) is an efficient implementation of the back-propagation algorithm for current-generation workstations. The algorithm includes a per-epoch adaptive technique for gradient descent. All the computations are done through matrix multiplications and make use of highly optimized C code. The goal is to reach almost peak-performances on RISCs with superscalar capabilities and fast caches. On some machines (and with large networks) a 30-40x speed-up can be measured respect to conventional implementations.
