A LearningRateSchedule that uses a piecewise constant decay schedule. tfm.optimization.lr_schedule.PiecewiseConstantDecayWithOffset The function returns a 1-arg callable to compute the piecewise constant when passed the current optimizer step. This can be useful for changing the learning rate value across different invocations of optimizer functions. Example: use a learning rate that's 1.0 for the first 100001 steps, 0.5 for the next 10000 steps, and 0.1 for any additional steps. You can pass this schedule directly into a tf.keras.optimizers.Optimizer as the learning rate.

The learning rate schedule is also serializable and deserializable using tf.keras.optimizers.schedules.serialize and tf.keras.optimizers.schedules.deserialize. class CosineDecayWithOffset: A LearningRateSchedule that uses a cosine decay with optional warmup. class DirectPowerDecay: Learning rate schedule follows lr * (step)^power. class ExponentialDecayWithOffset: A LearningRateSchedule that uses an exponential decay schedule. class LinearWarmup: Linear warmup schedule. class PiecewiseConstantDecayWithOffset: A LearningRateSchedule that uses a piecewise constant decay schedule.

The TensorFlow Model Optimization Toolkit is a suite of tools that users, both novice and advanced, can use to optimize machine learning models for deployment and execution. Supported techniques include quantization and pruning for sparse weights. There are APIs built specifically for Keras. For an overview of this project and individual tools, the optimization gains, and our roadmap refer to tensorflow.org/model_optimization.

The website also provides various tutorials and API docs. The toolkit provides stable Python APIs. For installation instructions, see tensorflow.org/model_optimization/guide/install.

A LearningRateSchedule that uses a cosine decay with optional warmup. tfm.optimization.lr_schedule.CosineDecayWithOffset See Loshchilov & Hutter, ICLR2016, SGDR: Stochastic Gradient Descent with Warm Restarts. For the idea of a linear warmup of our learning rate, see Goyal et al.. When we begin training a model, we often want an initial increase in our learning rate followed by a decay. If warmup_target is an int, this schedule applies a linear increase per optimizer step to our learning rate from initial_learning_rate to warmup_target for a duration of warmup_steps.

Afterwards, it applies a cosine decay function taking our learning rate from warmup_target to alpha for a duration of decay_steps. If warmup_target is None we skip warmup and our decay will take our learning rate from initial_learning_rate to alpha. It requires a step value to compute the learning rate. You can just pass a TensorFlow variable that you increment at each training step. Configuration for Adam optimizer with weight decay. Inherits From: BaseOptimizerConfig, Config, ParamsDict

tfm.optimization.opt_cfg.AdamWeightDecayConfig Returns a dict representation of params_dict.ParamsDict. For the nested params_dict.ParamsDict, a nested dict will be returned.
