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. how to get rid of paint smell on furniture
