neural networks - Choosing filter size, strides etc. in a filter layer size

Since neighboring pixels are strongly correlated (specially in lowest layers), it makes sense to reduce the size of the output by subsampling (pooling) the filter response. The further apart two pixels are from each other, the less correlated.neural networks - Choosing filter size, strides etc. in a filter layer sizeSince neighboring pixels are strongly correlated (specially in lowest layers), it makes sense to reduce the size of the output by subsampling (pooling) the filter response.
