WebJul 25, 2024 · Wavelet scattering (or scatter transform) generates a representation that’s invariant to data rotation/translation and stable to deformations of your data. Uninformative variations in your data are discarded — e.g. an audio sample time-shifted by various amounts. Information for downstream tasks like classification is preserved. WebApr 10, 2024 · I would give the data to a neural network after the wavelet transformation. The batch size is 375. the input data is always divisible by 375 (22500/375=60), but after the wavelet transformation it is no longer divisible. I have tested different data but the shape always changed. Example: input shape before transformation: (16, 22500) / (16 ...
