Query about weight filter size in AlexNet
조회 수: 1(최근 30일)
I have analysed the pretrained alexnet model. I have attached the screen shot. In that conv2 row, weights are given as 5*5*48*256. what is 48 here?. As per my knowledge, 48 represents the previous layer (number of channels in previous layer). but number of previous layer is 96 after pool1. likewise, same doubt in conv4 and conv5.
Can anyone explain this question?

The reason that the third dimension of weights in the mentioned layer is not the same as the number of channels in input is that the corresponding layer in AlexNet perform grouped Convolution.
