accordance with the needs of the chapters to learn, so always anxious. To the original most important part of the basic is not mastered directly to learn the new network structure and new models, which leads to low learning efficiency, until in the study encountered a bottleneck, just back to look at the Han Liqun Teacher's "Artificial Neural network

to the learning objective function in the input instanceThe inverse propagation algorithm for training neurons is as follows:C + + Simple implementation and testingThe following C + + code implements the BP network, through 8 3-bit binary samples corresponding to an expected output, training BP network, the last trained network can be the input three binary numb

common theory of neural network structure and working principle, simple and good understanding, recommended to watch2, the mathematical derivation of the inverse propagation algorithm, if it is too complicated to temporarily skip3,matlab Code and Image Library(1) Plain English explain the traditional neural networkFir

Introduction of artificial neural network and single-layer network implementation of and Operation--aforge.net Framework use (v)The previous 4 article is about the fuzzy system, it is different from the traditional value logic, the theoretical basis is fuzzy mathematics, so some friends looking a little confused, if interested in suggesting reference related book

convolution neural network is this, but the concrete implementation has multiple versions, I refer to the Matlab Deep Learning Toolbox Deeplearntoolbox, here the realization of CNN and the other biggest difference is the sampling layer has no weight and bias, Just a sample process for the convolution layer, the test dataset for this toolbox is minist, each image
