Learning rate finder handler for supervised trainers. While attached, the handler increases the learning rate in between two boundaries in a linear or exponential manner. It provides valuable information on how well the network can be trained over a range of learning rates and what can be an optimal learning rate.
WebJan 5, 2024 · The fastai library simplifies training fast and accurate neural nets using modern best practices. See the fastai website to get started. The library is based on research into deep learning best practices undertaken at fast.ai, and includes "out of the box" support for vision, text, tabular, and collab (collaborative filtering) models. The author uses fastai's learn.lr_find () method to find the optimal learning rate. Plotting the loss function against the learning rate yields the following figure: It seems that the loss reaches a minimum for 1e-1, yet in the next step the author passes 1e-2 as the max_lr in fit_one_cycle in order to train his model: learn.fit_one_cycle (6,1e-2)
