Webb24 mars 2024 · 1 Answer Sorted by: 13 The batch size is the amount of samples you feed in your network. For your input encoder you specify that you enter an unspecified (None) amount of samples with 41 values per sample. WebbEach pixel in the data set comprises a number in the range (0,255), depending on how dark the writing in the pixel is. This is normalized to lie in the range (0,1) by dividing all values by 255. This is a minimal amount of feature engineering that makes the model run better. X_train = X_train/255.0 X_test = X_test/255.0
