WebMar 1, 2024 · For learning rates which are too low, the loss may decrease, but at a very shallow rate. When entering the optimal learning rate zone, you'll observe a quick drop in the loss function. Increasing the learning rate further will cause an increase in the loss as the parameter updates cause the loss to "bounce around" and even diverge from the minima. WebApr 16, 2024 · Learning rates 0.0005, 0.001, 0.00146 performed best — these also performed best in the first experiment. We see here the same “sweet spot” band as in the first experiment. Each learning rate’s time to train grows linearly with model size. Learning rate performance did not depend on model size. The same rates that performed best for …
