kernel and step operation, There may be the wrong dimension (analogy 2x3 matrix can not be multiplied by the 2x4 matrix, you need to replace the 2x4 matrix into a 3x4 matrix, here is the matrix of the 2x4 to add a row of 0 elements, so that it becomes the matrix of 3x4), the default is 0, preferably set to (kW-1)/ 2, which is the width of the convolution core 1 and then divided by 2. The padh default is PADW, preferably set to (kH-1)/2, which is the high-1 convolution core and then divided by 2

Learning of Neural Networks 1, overviewThe most important nature for neural networks is the ability of the network to learn from the environment and improve its behavi

Reprint: http://www.cnblogs.com/jzhlin/archive/2012/07/30/bp_c.html In the last article, we introduce the basic model of BP neural network, some terms in the model and the mathematical analysis of the model, and have a preliminary understanding of its principle. Then how to use the program language to specifically implement it, will be the next issue we need to discuss. This paper chooses the C language to

structure (1). Intuition of CNNIn deep learning book, author gives a very interesting insight. He consider convolution and pooling as a infinite strong prior distribution. The distribution indicates, all hidden units share the same weight, derived from certain amount of the input and has Parallel invariant feature.Under Bayesian statistics, prior distribuion is a subjective preference of the model based on experience. and the stronger the prior distribution is, the higher impact it'll has on th

implication of this is that the statistical characteristics of the part of the image are the same as the rest. This also means that the features we learn in this section can also be used in other parts, so we can use the same learning features for all the locations on this image. More intuitively, when a small piece is randomly selected from a large image, such as 8x8 as a sample, and some features are learned from this small sample, we can apply the feature learned from this 8x8 sample as a de
