Max pool layer vs Convolution with stride performance

Question

In most of the architectures, conv layers are being followed by a pooling layer (max / avg etc.). As those pooling layers are just selecting the output of previous layer (i.e. conv), can we just use convolution with stride 2 and expect the similar accuracy results with reduced process need?

Ya I have tried it vgg19 network and it works – Ashish Misra Jun 12 '19 at 02:08 — Ashish Misra, Jun 12 '19 at 02:08

Yes that can be done. Its explained in the paper 'Striving for simplicity: The all convolutional net' https://arxiv.org/pdf/1412.6806.pdf. Quote from the paper:

'We find that max-pooling can simply be replaced by a convolutional layer with increased stride without loss in accuracy on several image recognition benchmarks'

Thanks for reply. So, why industry is keeping using max-pools? – Deniz Beker Jun 21 '17 at 09:42
