layer of the network consists of multiple feature mappings, each of which is mapped to a plane, and the weights of all neurons in the plane are equal. Each feature extraction layer (c-layer) in CNN is followed by a feature mapping layer (s-layer), a unique two-time feature extraction structure that enables CNN to have high distortion tolerance for input samples.According to Figure 1, the first input image through and 3 convolution cores (filters) and offset items for convolution, the C1 layer p

Shortly after the start of the project, there is a forum dedicated to exchanging learning experiences and questions, point here. The above comment is the problem I encountered, if you encounter a new problem, you can post to the forum for help. I see some people generate music that has that weird Gothic-style haha.3.

Because we do not have a good understanding of the brain, we often try to use the latest technology as a model to explain it. When I was a child, we all beli
Currently, Java is used to develop the largest number of ape programs, but most of them are limited to years of development. In fact, Java can do more and more powerful!
I used Java to build a [self-built neural network] instead of laboratory work, it is a real, direct application that makes our programs smarter, let our program have the perception or cognitive function! Do not use the same number as the neural

Application examples of RNN--a language model based on RNN
Now, let's introduce a model based on the RNN language. We first input the word into the recurrent neural network, each input word, the recurrent neural network output so far, the next most likely word. For example, when we enter in turn:

ManualNeural Network (ANN)It is an important branch of AI. After decades of development, artificial neural networks have been widely applied to business problems in the real world. Artificial neural networks can be widely used in Machine Fault Diagnosis, medical diagnosis, speech recognition, and securities management.
The fourth lecture of Professor Geoffery Hinton's Neuron Networks for machine learning mainly describes how to use the back propagation algorithm to learn the characteristic representation of a vocabulary.Learning to predict the next wordThe next few sections focus on how to use the back propagation algorithm to learn the feature representation of a vocabulary. Starting with a very simple example, we introduce the use of the back propagation algorithm
Linear regression and logistic regression are sufficient to solve some simple classification problems, but in the face of more complex problems (such as identifying the type of car in the picture), using the previous linear model may not result in the desired results, and due to the larger data volume, the computational complexity of the previous method will become unusually large. So we need to learn a nonlinear system: neural networks.When I was stu

IntroductionIn the previous chapter, although the BP neural network has made great progress, but it has some unavoidable problems, one of which is more confused is the problem of local optimal solution.
