PyTorch Implementation

import torch.optim as optim
from torch.optim.lr_scheduler import StepLR

optimizer = optim.Adam(model.parameters(), lr=0.001)
scheduler = StepLR(optimizer, step_size=30, gamma=0.1)

for epoch in range(100):
    train(...)
    scheduler.step()
                        

💡 Best Practices

  • Step decay works well for image classification tasks
  • Use warmup when training with large batch sizes
  • Monitor validation loss to avoid premature decay
