Forecasting is the process of
- Compare metric scores with the baseline scores to see if there's an improvement or not
- Start with accuracy and point-wise accuracy, if there is a significant increase in both as compared to baseline then the model is learning useful patterns. The percentage increase varies greatly from case to case and is dependent on a variety of factors
If all of the above things look good then the model is good to go and you have trained a world-class deep learning-based forecasting model in just a few minutes with only a few clicks.
