In the case of a one-dimensional array of n features, the input_shape looks like this (batch_size, n). As I mentioned before, we can skip the batch_size when we define the model structure, so in the code, we write: 1. keras.layers.Dense(32, activation='relu', input_shape=(16,)) When using this layer as the first layer in a model, provide an input_shape argument (tuple of integers or None, e.g. (10, 128) for sequences of 10 vectors of 128-dimensional vectors, or (None, 128) for variable-length sequences of 128-dimensional vectors.
