TensorFlow 2 version View source on GitHub

A LearningRateSchedule that uses a polynomial decay schedule.

Inherits From: LearningRateSchedule

initial_learning_rate A scalar float32 or float64 Tensor or a Python number. The initial learning rate.
decay_steps A scalar int32 or int64 Tensor or a Python number. Must be positive. See the decay computation above.
end_learning_rate A scalar float32 or float64 Tensor or a Python number. The minimal end learning rate.
power A scalar float32 or float64 Tensor or a Python number. The power of the polynomial. Defaults to linear, 1.0.
cycle A boolean, whether or not it should cycle beyond decay_steps.
name String. Optional name of the operation. Defaults to 'PolynomialDecay'.
