Super-Convergence: Train Neural Networks Much Faster Than Before

Researchers found a way to make neural networks learn way quicker, and it can feel almost like a shortcut. This trick, called super-convergence, lets models reach strong results in a fraction of the time by using one training cycle and a very big learning rate. Big rates do something helpful — they act like a kind of regularizer, so you actually need less other tuning to stop overfitting. The method works across many image tasks and different network styles, and it shows up more when training data is scarce, so it helps when labels are few. You can try it without changing your whole setup, it mostly needs adjusting how fast the model learns during training. Results were surprising; training that used to …
