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. There was an error while loading. Please reload this page.

In this post we will introduce the key hyperparameters involved in cosine decay and take a look at how the decay part can be achieved in TensorFlow and PyTorch. In a subsequent blog we will look at how to add restarts.

A cosine learning rate decay schedule drops the learning rate in such a way it has the form of a sinusoid. Typically it is used with “restarts” where once the learning rate reaches a minimum value it is increased to a maximum value again (which might be different from the original max value) and it... The equation for decay as stated in SGDR: Stochastic Gradient Descent with Warm Restarts is as follows where $i$ means the $i$-th run of the decay. Here will consider a single such run. The equation can be expanded (dropping the $i$ superscript) as the sum of a constant and a term that decays over the period $T$ and denoting $T_\text{cur}$ as $t$.

I am training a neural network in TensorFlow and I would like to use firstly an exponential decay optimizer scheduler (https://www.tensorflow.org/api_docs/python/tf/keras/optimizers/schedules/ExponentialDecay) and then also a cosine decay (https://www.tensorflow.org/api_docs/python/tf/keras/optimizers/schedules/CosineDecay).
