Metrics: MSE, RMSE, MAE, RMSLE

[justusschock]

🚀 Feature

Implement the following as metrics (grouped due to similarity):

• MSE
• RMSE
• MAE
• RMSLE

Note: Probably it suffices for some of them to derive a new class from the loss variant in torch.nn and the BaseMetric class

@cuent ^^ mind type anything so I can assign it to you... 🐰

Thanks 😄 Will try to push tmrr!

For anyone landing here from a search engine: The situation has changed since 2020 and almost all are available in TorchMetrics, an official PyTorch Lightning project to outsource metrics.

• MSE
• RMSE
  • torch.sqrt(mse(y, y_hat))
• MAE
• RMSLE
  • torch.sqrt(msle(y, y_hat))
  • Using MSLE
