The author says: Before having studied once, but after a period of time, many details place already blurred. Recently deduced again, in order to retain as far as possible the derivation idea, specially writes this blog post. On the one hand for their future memories, on the other hand to communicate with you to learn.For this blog post, the following description:1. This blog does not guarantee that the derivation process is completely correct, if there is a problem, please correct me.2. If neces
Motive (motivation)For non-linear classification problems, if multiple linear regression is used to classify, it is necessary to construct many high-order items, which leads to too many learning parameters, so the complexity is too high.Neural networks (Neural network)As shown in a simple neural network, each circle re

So if a neuron wants to deliver a message, it sends a faint current to other neurons through its axis bursts.2 , the yellow circle represents a neuron, X is the input vector, and θ represents the weight of the neuron (which is actually the model parameter we described earlier), and hθ (X) represents the excitation function (in neural network terminology, the ex

convolutional neural Network (CNN) is the foundation of deep learning. The traditional fully-connected neural network (fully connected networks) takes numerical values as input.If you want to work with image-related information, you should also extract the features from the image and sample them. CNN combines features,
I. Convolutionconvolutional Neural Networks (convolutional neural Networks) are neural networks that share parameters spatially. Multiply by using a number of layers of convolution, rather than a matrix of layers. In the process of image processing, each picture can be regarded as a "pancake", which includes the height of the picture, width and depth (that is, co

Just entered the lab and was called to see CNN. Read some of the predecessors of the blog and paper, learned a lot of things, but I think some blog there are some errors, I try to correct here, but also added their own thinking and deduction. After all, the theory of CNN has been put forward, I just want to be able to objectively describe it. If you feel that there is something wrong with this article, be sure to tell me in the comments below.convolutional n
really simple, very mathematical beauty. Of course, as a popular science books, it will not tell you how harmful this method is.Implementation, you can use the following two algorithms:①KMP: Put $w_{i}$, $W _{i-1}$ two words together, run once the text string.②ac automaton: Same stitching, but pre-spell all the pattern string, input AC automaton, just run once text string.But if you are an ACM player, you should have a deep understanding of the AC automaton, which is simply a memory killer.The
If you use 100k batch in this model, and combine the decay of learning rate (that is, the rate of learning is reduced by a ratio every once in a while), the correct rate can be as high as 86%. There are about 1 million parameters to be trained in the model, and the total amount of arithmetic to be estimated is about 20 million times. So this convolution neural network model, using some techniques.(1) Regula
Neural NetworkIt is a system that can adapt to the new environment. It has the ability to analyze, predict, reason, and classify the past experience (information, it is a system that can emulate the human brain to solve complex problems. Compared with conventional systems (using statistical methods, pattern recognition, classification, linear or nonlinear methods, A Neural

Neuron Model Neurons can be thought of as a computational unit that receives certain information from the input nerves, makes some calculations, and then transmits the results to other nodes or other neurons in the brain through axons.The neuron is modeled as a logical unit, as follows: In, the input unit is X1 X2 X3, sometimes can also be added x0 as offset units, the value of x0 is 1, whether to add bias units depends on whether it is advantageous to the example.The Orange small Circle in th

1. OverviewWe have already introduced the earliest neural network: Perceptron. A very deadly disadvantage of the perceptron is that its linear structure, which can only make linear predictions (even if it does not solve the regression problem), is a point that was widely criticized at the time.Although the perceptual machine can not solve the nonlinear problem, it provides a way to solve the nonlinear probl
