## Optional model hooks.
Add these to the model whenever you want to configure training behavior.
### Add new model
1. Create a new model under /models.
2. Add model name to trainer_main
```python
AVAILABLE_MODELS = {
'model_1': ExampleModel1
}
```
### Model methods that can be implemented
| Method | Purpose | Input | Output | Required |
|---|---|---|---|---|
| forward() | Forward pass | model_in tuple with your data | model_out tuple to be passed to loss | Y |
| loss() | calculate model loss | model_out tuple from forward() | A scalar | Y |
| check_performance() | run a full loop through val data to check for metrics | dataloader, nb_tests | metrics tuple to be tracked | Y |
| tng_dataloader | Computed option, used to feed tng data | - | Pytorch DataLoader subclass | Y |
| val_dataloader | Computed option, used to feed tng data | - | Pytorch DataLoader subclass | Y |
| test_dataloader | Computed option, used to feed tng data | - | Pytorch DataLoader subclass | Y |
