Webshift-invariant approach, The first point is explained above. To implement the second one, there is two possibility, either slicing the input timeseries into small overlapping samples or to have atoms smaller than input samples, leading to a decomposition with sparse coefficients and offsets. WebJul 18, 2024 · After doing the above, every layer in the network is now a shift-invariant operation, and should be able to process input images of any size. If I input a 400x400 image A, the output of the network should be an N-channel image of size 371x371 where each pixel contains the N class probabilities of a particular 30x30 sub-block.
