, in fact, all the filter and all the local area of the dot product operation, of course, this result also needs to be re-reshape to the desired output size. This process also explains why the parameters of a neuron can be stored in a filter and why the network layer is called a convolution layer. 2. Output image size after convolution:assuming the input image size is W, the convolution core size is F, the Stride (

Python implements a simple convolutional network framework

The first step is to define the convolution kernel class:Class Filter (object): # Filter Class initializes the convolution core def __init__ (self,width,height,depth): # Initialize the filter Parameter self.weights=np.random.uniform ( -1e-4,1e-4, (depth,height,width)) self.bias=0 self.weights _grad=np.zeros (self.weights.shape) self.bias_grad=0 def get_weights (self): return self.weights def get_bias (self): return Self.bias def upd

same time; second, the memory data is copied to the data, after processing, copying the array data will reduce the memory speed. As an improvement, we should make full use of lockbits. In lockbits, there is a mode in lockmode: imagelockmode. userinputbuffer. In this mode, the user needs to apply for memory first, and then fill the image data in the relevant format such as this memory. In this way, you can define an array and then fill the image data in this array to avoid the time required to c
