MinMaxNorm weight constraint.
Inherits From: Constraint
tf.keras.constraints.MinMaxNorm( min_value=0.0, max_value=1.0, rate=1.0, axis=0 )
Constrains the weights incident to each hidden unit to have the norm between a lower bound and an upper bound.
Also available via the shortcut function tf.keras.constraints.min_max_norm
.
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) . |
