Maximally flat (maxflat) digital filter design in Java, with arbitrary numbers of poles and zeros. "Maximally flat" means that the magnitude frequency response has the maximum number of vanishing derivatives at 0 and pi.
SNARLI (Simple Neural ARchitecture LIbrary) is a Java package containing a back-prop layer class and classes for the Self-Organizing Map and Incremental Growing Grid. The back-prop class supports sigma-pi connections and back-prop-through-time.
