Analysis
This is a fantastic exploration of optimizing time-series forecasting models for renewable energy! The use of RMSE and MAE for evaluation, coupled with MSE for backpropagation, reveals a pragmatic approach to bridging the gap between model training and real-world application, offering increased accuracy.
Key Takeaways
- •The article explores the practical use of different loss functions in deep learning for time-series forecasting, specifically within the context of solar energy.
- •It highlights a common practice of using MSE for training due to its mathematical properties, while evaluating with RMSE/MAE for interpretable results.
- •The discussion centers on whether it's acceptable to optimize hyperparameters using a metric (RMSE) different from the training loss (MSE).
Reference
“Is it "cheating" or bad practice to optimize hyperparameters based on a metric (RMSE) that isn't exactly the loss function used for weights updates (MSE)? Or is this standard industry procedure?”
