✦ Synopsis

This paper introduces a new class of sign-based training algorithms for neural networks that combine the sign-based updates of the Rprop algorithm with the composite nonlinear Jacobi method. The theoretical foundations of the class are described and a heuristic Rprop-based Jacobi algorithm is empirically investigated through simulation experiments in benchmark pattern classification problems. Numerical evidence shows that this new modification of the Rprop algorithm exhibits improved learning speed in all cases tested, and compares favorably against the Rprop and a recently proposed modification, the improved Rprop.

A tripartite classification of gravel beaches, based upon morphodynamic properties, is proposed and demonstrated for 42 New Zealand beaches. The main advantage of this scheme is that it is based on simple visual classification that can be applied globally in the field and is underpinned by morphodyn
