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;

To my understanding, you wanted to implement groupedConvolution2dLayer into Keras/Tensorflow.
One possible workaround is you can use 'exportONNXNetwork' to export whole network to ONNX model format. Then, you can use the ONNX Model to import it to Keras/Tensorflow.
You can refer to exportONNXNetwork MathWorks documentation page to find more on exporting network to ONNX model format.
