问题 For my project I need to initialize the CNN 1st Layer kernel with Gammatone filters according to papers ( https://www.mdpi.com/1099-4300/20/12/990/htm ) ,( https://www.groundai.com/project/end-to-end-environmental-sound-classification-using-a-1d-convolutional-neural-network/1 ) and a few others. What does it exactly mean to initialize the cnn kernel with Gammatone filter (Or any filter). How does one implement it? Is it a custom layer? Any tips and guidance would be much appreciated! for
