WebApr 5, 2024 · Cyclical learning rate(CLR) allows keeping the learning rate high and low, causing the model not to diverge along with jumping from the local minima. WebFeb 19, 2024 · After the cycle is complete, the learning rate should decrease even further for the remaining iterations/epochs, several orders of magnitude less than its initial value. Smith named this the 1cycle policy. … WebDec 2, 2024 · The Lr Range test gives the maximum learning rate, and the minimum learning rate is typically 1/10th or 1/20th of the max value. One cycle consists of two-step sizes, one in which Lr increases from the min to max and the other in which it decreases from max to min. fachbereich soziales cottbus
