A neural network is a data processing system consisting of a large number of simple, highly interconnected processing elements in an architecture inspired by the structure of the cerebral cortex portion of the brain. Hence, neural networks are often capable of doing things which humans or animals ...
Introduction to ANN Def: A structure (network) composed of a number of interconnected units (artificial neurons). Each unit has an I/O characteristic and implements a local computation or function. The output of any unit is determined by its I/O characteristic, its interconnection to other unit...
第十章:Introduction to Artificial Neural Networks 人工神经网络(artificial neural networks, ANNs)是人们受生物大脑神经系统启发提出的一种数学模型。具体来说,它是人们基于生物神经网络的基本原理,在理解和抽象了人脑结构和外界刺激响应机制后,以网络拓扑知识为理论基础,模拟人脑的神经系统对复杂信息的处理机制建立的数...
An artificial neural network is a system and this system is a structure which receives an input, processes the data and provides an output. The input in data array will be WAVE sound, a data from an image file or any kind of data that can be represented in an array. Once an input is...
