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. WebAug 13, 2016 · Restart techniques are common in gradient-free optimization to deal with multimodal functions. Partial warm restarts are also gaining popularity in gradient-based optimization to improve the rate of convergence in accelerated gradient schemes to deal with ill-conditioned functions.
