# tf.keras.constraints.MinMaxNorm

## Class MinMaxNorm

Inherits From: Constraint

### Aliases:

• Class tf.keras.constraints.MinMaxNorm
• Class tf.keras.constraints.min_max_norm

MinMaxNorm weight constraint.

Constrains the weights incident to each hidden unit to have the norm between a lower bound and an upper bound.

#### Arguments:

• min_value: the minimum norm for the incoming weights.
• max_value: the maximum norm for the incoming weights.
• rate: rate for enforcing the constraint: weights will be rescaled to yield (1 - rate) * norm + rate * norm.clip(min_value, max_value). Effectively, this means that rate=1.0 stands for strict enforcement of the constraint, while rate<1.0 means that weights will be rescaled at each step to slowly move towards a value inside the desired interval.
• axis: integer, axis along which to calculate weight norms. For instance, in a Dense layer the weight matrix has shape (input_dim, output_dim), set axis to 0 to constrain each weight vector of length (input_dim,). In a Conv2D layer with data_format="channels_last", the weight tensor has shape (rows, cols, input_depth, output_depth), set axis to [0, 1, 2] to constrain the weights of each filter tensor of size (rows, cols, input_depth).
