I am implementing layers for both Keras and MATLAB, but not sure how MATLAB implements groupedConvolution2dLayer.
Ahough MATLAB document describes groupedConvolution2dLayer could be converted into either DepthwiseConv2D or SeparableConv2D,
It seems like groupedConvolution2dLayer did more than that.
Does anyone know how to convert this into Keras layer or Tensorflow?
filterSize = [7 7];
numFiltersPerGroup = 16;
numGroups = 4;
