Hi guys
I want to use alexnet for feature extraction.I was wondering if could tell me how to feed my as image into alexnet?

alexnet uses overlapping pooling, the first conv layer's pooling should use (3, 3) kernel with stride 2 according to the original paper.

model.add(MaxPooling2D(poolsize=(3, 3), strides=2))

why your Convolution2D have four customized parameters? currently version's keras only need 3 params..??

This link is awesome but its not in keras but tensorflow..
Here's the github link..

You can find 2-stream AlexNet here: http://dandxy89.github.io/ImageModels/alexnet/
