of the original signal. That is because the data gets normalized across the pictures. In my analysis I only want to detect large signals not tiny signals. This is critical. I am new to this type of work so my question may seem naive, but is normalization required for the cnn to work?

datagen=image.ImageDataGenerator(featurewise_center=True,featurewise_std_normalization=True) featurewise_center的官方解释:"Set input mean to 0 over the dataset, feature-wise." 大意为使数据集去中心化(使得其均值为0),而samplewise_std_normalization的官方解释是“ Divide inputs by std of the dataset, ...
Added in v0.11.0 This transform returns the input unchanged. It can be used for simplifying the code in cases where data augmentation should be disabled. LowPassFilter Added in v0.8.0 Apply low-pass filtering to the input audio. PeakNormalization ...

The effect of both dropout and batch normalization regularization techniques on network performance was evaluated separately and in combination. Two additional regularization techniques, namely the max–norm regularization and weight decay were also evaluated. It took approximately three months on two NVIDIA...
