  • In the context of Deep Learning, what is training warmup steps

    stackexchange.com

    https://datascience.stackexchange.com/questions/55991/in-the-context-of-deep-learning-what-is-training-warmup-steps

    WEBJul 19, 2019 · Warm-up is a way to reduce the primacy effect of the early training examples. Without it, you may need to run a few extra epochs to get the convergence desired, as the model un-trains those early superstitions. Many models afford this as a command-line option. The learning rate is increased linearly over the warm-up period.

    WEBAug 14, 2020 · In the above code, self.last_epoch is the current training iteration (because maskrcnn-benchmark use iteration instead of the usual epoch to measure the training process). self.warmup_iters is the number of iterations for warmup in the initial training stage. self.warmup_factors are a constant (0.333 in this case).

    WEBMar 18, 2024 · We denote by the initial LR and the number of warm-up steps (epochs or iterations): Constant Warm-up: a constant LR value is used to warm up the network. Then, the training directly starts with LR . One drawback is the abrupt change of LR from to ; Gradual or linear Warm-up: the warm-up starts at LR and linearly increases to in steps.
