tf.compat.v1.keras.layers.experimental.preprocessing.Normalization

Feature-wise normalization of the data.

Inherits From: Normalization

tf.compat.v1.keras.layers.experimental.preprocessing.Normalization(
    axis=-1, dtype=None, **kwargs
)

This layer will coerce its inputs into a normal distribution centered around 0 with standard deviation 1. It accomplishes this by precomputing the mean and variance of the data, and calling (input-mean)/sqrt(var) at runtime.

What happens in adapt: Compute mean and variance of the data and store them as the layer's weights. adapt should be called before fit, evaluate, or predict.

Attributes
axis	Integer or tuple of integers, the axis or axes that should be normalized (typically the features axis). We will normalize each element in the specified axis. The default is '-1' (the innermost axis); 0 (the batch axis) is not allowed.

adapt(
    data, reset_state=True
)

Fits the state of the preprocessing layer to the data being passed.

Arguments
data	The data to train on. It can be passed either as a tf.data Dataset, or as a numpy array.
reset_state	Optional argument specifying whether to clear the state of the layer at the start of the call to adapt, or whether to start from the existing state. Subclasses may choose to throw if reset_state is set to 'False'.
