Deep learning series notes 03 multilayer perceptron

1 perceptron The output of the perceptron can be set to 0 or 1; Or - 1, 1. By continuously introducing data points, this line can effectively segment all kinds of training data. It is worth noting that the convergence theorem is a concept in mathematical statistics. Points cannot be taken on the plane to separate such two data (red ...

Image convolution operation

image convolution 1 cross correlation operation Strictly speaking, convolution layer is a wrong name, because the operation it expresses is actually cross-correlation operation, not convolution operation. In the convolution layer, the input tensor and kernel tensor generate the output tensor through cross-correlation operation. First, let's ...
