To overcome the shortage of the conventional Back-propagation (BP) Network, the BP network is trained by using one step secant (OSS) algorithm. According to the Yangtze River water statistics reported from 1995
The one step secant (OSS) method is an attempt to bridge the gap between the conjugate gradient algorithms and the quasi-Newton (secant) algorithms. This algorithm does not store the complete Hessian matrix; it assumes that at each iteration, the previous Hessian was the identity matrix. This...
TL;DR: In our recent paper Adaptive Open-Loop Step-Sizes for Accelerated Convergence Rates of the Frank-Wolfe Algorithm with Elias Wirth and Javier Peña, we explore a new “log-adaptive” open-loop step-size for the Frank-Wolfe algorithm, ηt=2+log(t+1)t+2+log(t+1), which...
ANN is an ML method that uses past data to predict future trends, while GA is an algorithm that can find better subsets of input variables for importing into ANN, enabling more accurate prediction by its efficient feature selection [24, 252]. Another family of algorithms for global optimiza-...
