Cosine annealing + warm restarts
WebIt has been proposed in SGDR: Stochastic Gradient Descent with Warm Restarts. Note that this only implements the cosine annealing part of SGDR, and not the restarts. … WebArgs: global_step: int64 (scalar) tensor representing global step. learning_rate_base: base learning rate. total_steps: total number of training steps. warmup_learning_rate: initial learning rate for warm up. warmup_steps: number of warmup steps. hold_base_rate_steps: Optional number of steps to hold base learning rate before decaying.

WebWarm restarts are usually employed to improve the convergence rate rather than to deal with multimodality: often it is sufficient to approach any local optimum to a given precision and in many cases the problem at hand is unimodal. Fletcher & Reeves (1964) proposed to flesh the history of conjugate gradient method every nor (n+ 1) iterations. WebLinear Warmup With Cosine Annealing. Edit. Linear Warmup With Cosine Annealing is a learning rate schedule where we increase the learning rate linearly for n updates and then anneal according to a cosine schedule afterwards.
WebAug 2, 2024 · Within the i-th run, we decay the learning rate with a cosine annealing for each batch [...], as you can see just above Eq. (5), where one run (or cycle) is typically one or several epochs. Several reasons could motivate this choice, including a large dataset size. With a large dataset, one might only run the optimization during few epochs. WebDec 23, 2024 · Below is a demo image of how the learning rate changes.
