WebSep 17, 2024 · 2. Warm-up Steps. For the linear scheduler that we used, we can apply warm-up steps. For example, applying 50 warm-up steps means the learning rate will increase linearly from 0 to the initial learning rate set in the optimizer during the first 50 steps (warm-up phase). After that, the learning rate will start to decrease linearly to 0. WebModels often benefit from reducing the learning rate by a factor of 2-10 once learning stagnates. This scheduler reads a metrics quantity and if no improvement is seen for a ‘patience’ number of epochs, the learning rate is reduced. Parameters: optimizer ( Optimizer) – Wrapped optimizer. mode ( str) – One of min, max.
