Webb10 apr. 2024 · Since the amplitudes of traffic noise are larger than those of the reflections in data, to prevent the poor performance of the ACB-UNet, we need to normalize the data to the range of [−1, 1], which is better adapted to the network. We can split the data into small patches to reduce computational time and memory consumption to train the network.
