convolution neural network is this, but the concrete implementation has multiple versions, I refer to the Matlab Deep Learning Toolbox Deeplearntoolbox, here the realization of CNN and the other biggest difference is the sampling layer has no weight and bias, Just a sample process for the convolution layer, the test dataset for this toolbox is minist, each image
Neural network and deep learning the book has been read several times, but each time there will be a different harvest.The paper of DL field is changing rapidly. There's a lot of new idea coming out every day, I think. In-depth reading of classic books and paper, you will be able to find Remian open problems. So there's a different perspective.Ps:blog is a summar

Using neural networks to recognize handwritten numbers
How
The exercise needs to complete the calculations of forward pass,cost,error and gradient in CNN. It is necessary to understand the principle of the above four steps in each layer, and to make full use of MATLAB matrix operations. Probably summed up the process as shown:STEP 1:implement CNN ObjectiveSTEP 1a:forward PropagationForward propagation is mainly to calculate the output of the input image after the neural
In front of us, we talked about the DNN, and the special case of DNN. CNN's model and forward backward propagation algorithms are forward feedback, and the output of the model has no correlation with the model itself. Today we discuss another type of neural network with feedback between output and model: Cyclic neural network

The sensor was invented by science and technology Frank Rosenblatt in and was influenced by Warren McCulloch and Walter Pitts's early work. Today, the use of other Artificial Neuron models is more common-in this book, and more modern neural networks work, primarily usi
