This document references: http://www.cnblogs.com/tornadomeet/p/3468450.htmlThank you for that.Generally speaking, the output of a multi-class neural network is generally in softmax form, that is, the activation function of the output layer does not use sigmoid or Tanh functions. Then the output of the last layer of the neural
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

Recently, the Google deep Mind team put forward a machine learning model, and a particularly tall on the name: Neural network Turing machine, I translated this article for everyone, translation is not particularly good, some sentences did not read clearly, welcome everyone to criticize

seen before, and if it has a similar word (similar in meaning) to the sentence we have seen, it will have a higher probability, so that it will gain generalization. It is challenging to train such a large model (with millions of parameters) within a reasonable time. The report that we use neural networks to compute probability functions shows that the method presented in two text corpora significantly improves the most advanced n-ary syntax model, an
friendly experience. The main purpose of this paper is to help readers understand how convolutional neural networks are used in images.
If you are completely unfamiliar with neural networks, it is recommended to read 9 lines of Python code to build a neural network to master some basic concepts. In this paper, Multila

Cyclic neural networks (recurrent neural networks,rnns) have been successful and widely used in many natural language processing (Natural Language processing, NLP). However, there are few learning materials related to Rnns online, so this series is to introduce the principle of rnns and how to achieve i

The convolution layer differs from the previous fully connected layer by using some techniques to avoid excessive number of parameters, but preserve

Here is the [1] derivation of the BP algorithm (backpropagation) steps to tidy up, memo Use. [1] the direct use of the matrix differential notation is deduced, the whole process is very concise. And there is a very big advantage of this matrix form is that it is very convenient to implement the programming Control.But its practical scalar calculation deduction also has certain advantages, for example, can clearly know that a weight is affected by who.Marking Conventions:$L $: The number of layer

This chapter may be the most unclear chapter of Andrew Ng, why do you say so? This chapter focuses on the back propagation (backpropagration, BP) algorithm, Ng spent half time talking about how to calculate the error item δ, how to calculate the δ matrix, and how to use MATLAB to achieve the post transmission, but the most critical question-why so calculate. The previous calculation of these amounts represents what, Ng basically did n
I've been focusing on CNN implementations for a while, looking at Caffe's code and Convnet2 's code.
