WebMaybe the optimizer benchmarks change completely for a different learning rate schedule, and vice versa. Ultimately, these things are semi random choices informed by fashions … Initial rate can be left as system default or can be selected using a range of techniques. A learning rate schedule changes the learning rate during learning and is most often changed between epochs/iterations. This is mainly done with two parameters: decay and momentum . There are many different learning rate schedules but the most common are time-based, step-based and exponential.
