## Classes

[`class Constraint`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/keras/constraints/Constraint): Base class for weight constraints.

[`class MaxNorm`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/keras/constraints/MaxNorm): MaxNorm weight constraint.

[`class MinMaxNorm`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/keras/constraints/MinMaxNorm): MinMaxNorm weight constraint.

[`class NonNeg`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/keras/constraints/NonNeg): Constrains the weights to be non-negative.

[`class RadialConstraint`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/keras/constraints/RadialConstraint): Constrains `Conv2D` kernel weights to be the same for each radius.

[`class UnitNorm`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/keras/constraints/UnitNorm): Constrains the weights incident to each hidden unit to have unit norm.

[`class max_norm`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/keras/constraints/MaxNorm): MaxNorm weight constraint.

[`class min_max_norm`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/keras/constraints/MinMaxNorm): MinMaxNorm weight constraint.

[`class non_neg`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/keras/constraints/NonNeg): Constrains the weights to be non-negative.

[`class radial_constraint`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/keras/constraints/RadialConstraint): Constrains `Conv2D` kernel weights to be the same for each radius.

[`class unit_norm`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/keras/constraints/UnitNorm): Constrains the weights incident to each hidden unit to have unit norm.
