1. **StepLR**: Decreases the learning rate by a factor of `gamma` every `step_size` epochs. 2. **ReduceLROnPlateau**: Reduces the learning rate when a metric has stopped improving. This is particularly useful for metrics like validation los…

- Use `torch.cuda.amp` to enable mixed precision training with `GradScaler` and `autocast`. ### Additional Considerations - **Batch Size**: Adjust the batch size based on the available VRAM. For example, if your GPU has 16 GB of VRAM, …
