keras convolutional neural network

In this blog post we briefly analyze the class--layers of the last network structure in the TINY_CNN convolutional neural network model.First of all, layers can be called a layer structure of the vector, that is, the layer structure of the container. Because convolutional

Original articleReprint please register source HTTP://BLOG.CSDN.NET/TOSTQ the previous section we introduce the forward propagation process of convolutional neural networks, this section focuses on the reverse propagation process, which reflects the learning and training process of neural networks. Error back propagation method is the basis of

In Keras, a neural network visualization function plot is provided, and the visualization results can be saved locally. Plot use is as follows: From Keras.utils.visualize_util import plot plot (model, to_file= ' model.png ') Note: The author uses the Keras version is 1.0.6, if is python3.5 From keras.utils import

Turn from: The Heart of the machine Introduction Frankly speaking, I can't really understand deep learning for a while. I look at relevant research papers and articles and feel that deep learning is extremely complex. I try to understand neural networks and their variants, but still feel difficult. Then one day, I decided to start with a step-by-step basis. I break down the steps of technical operations and manually perform these steps (and calcula

Study, the use of convolutional neural network has been a long time, the period has been based on the Caffe framework of the Jiayanqing great God to study other people's model, or in the boring time in the same way as the fortune-telling, eyes micro-closed, bobbing, the mouth occasionally leaking a few syllables, a long time DIY out of a think of a lot of models,

convolutional Neural Networks (convolution neural network, CNN) have achieved great success in the field of digital image processing, which has sparked a frenzy of deep learning in the field of natural language processing (Natural Language processing, NLP). Since 2015, papers on deep learning in the field of NLP have e

Kalchbrenner ' s PaperKal's article cited a high number of citations, he proposed a network model called DCNN (Dynamic convolutional neural Networks), in the previous (Kim's Paper) experimental results Section also verified the effectiveness of this model. The subtleties of this model lie in the way of pooling, using a method 动态Pooling called.Is the model of th

biased term, followed by a nonlinear function. If you use $h ^{k}$ to represent the feature map of the $k $ layer, the corresponding filter is determined by the $W ^{k}$ and bias $b _{k}$, then the feature map $h ^{k}$ can be computed from the next (using Tanh for nonlinear functions):$h _{ij}^{k}=tanh (w^{k}*x) _{ij}+b_{k}$In order to get a richer representation of the data, each hidden layer is usually composed of multiple feature graphs: $\{h^{\text{(k)}},k=0,... k\}$. The weight $W $ is rep

Transferred from: http://blog.csdn.net/u014380165/article/details/77284921 We know that convolutional neural Network (CNN) has been widely used in the field of image, in general, a CNN network mainly includes convolutional layer, pool layer (pooling), fully connected layer,

C ++ convolutional neural network example: tiny_cnn code explanation (10) -- layer_base and layer Class Structure Analysis In the previous blog posts, we have analyzed most of the layer structure classes. In this blog post, we plan to address the last two layers, it is also the two basic classes layer_base and layer that are at the bottom of the hierarchy for a b
