In this paper a critical review of gradient-based training methods for recurrent neural networks is presented including Back Propagation Through Time (BPTT), Real Time Recurrent Learning (RTRL) and several specific learning algorithms for different locally recurrent architectures. From this survey it comes out the need for a unifying view of all the specific procedures proposed for networks wit...

Research on fault diagnosis and positioning of the distribution network (DN) has always been an important research direction related to power supply safety performance. The back propagation neural (BPNN) is a commonly used intelligent algorithm for location in DN. To improve accuracy dual DN, this study optimizes BPNN by combining genetic (GA) cloud theory. two types before after optimization a...

In this paper, we proposed the design method of artificial neural networks using VHDL and implement in FPGA. VHDL is a programming language that has been designed and optimized for describing the behavior of digital systems. Back propagation algorithm for the design of a neuron is described. Back propagation is popular training algorithms for multilayer perceptrons. Over the last years many imp...

The two well known learning algorithms of recurrent neural networks are the back-propagation (Rumelhart & el al., Werbos) and the forward propagation (Williams and Zipser). The main drawback of back-propagation is its off-line backward path in time for error cumulation. This violates the on-line requirement in many practical applications. Although the forward propagation algorithm can be used i...

the goal of this study was to predict the moisture content of paddy using machine vision and artificial neural networks (anns). the grains were dried as thin layer with air temperatures of 30, 40, 50, 60, 70, and 80°c and air velocities of 0.54, 1.18, 1.56, 2.48 and 3.27 ms-1. kinetics of l*a*b* were measured. the air temperature, air velocity, and l*a*b* values were used as ann inputs. the res...
