Deep Learning (DL) and convolutional Neural Network (CNN) learning notes essay -01-CNN Basics points

similar to the dimensionality reduction) method. Maximum pooling divides the input image into overlapping image matrix blocks, and each sub-region outputs its maximum value. The two reasons why the maximum pooling method is very effective in the visual processing problem are:(1) Reduce the computational complexity of the upper level by reducing the non-maximum value.(2) The result of pooling supports translation invariance. In the convolution layer, each pixel point has 8 orientations that can

outputLength. Training instances that has inputs longer than I or outputsLonger than O'll be pushed to the next bucket and padded accordingly.We assume the list is sorted, e.g., [(2, 4), (8, 16)]. Size:number of units in each layer of the model. Num_layers:number of layers in the model. Max_gradient_norm:gradients'll is clipped to maximally this norm. Batch_size:the size of the batches used during training;The model construction is independent of batch_size, so it can beChanged
