Hi, I am using a tabular_learner in order to try and predict (insurance) exposure for a given set of vehicle attributes and was wondering what the reported error is?
After calling lr_find() and then fitting the model using this selected learning rate I see a train_loss, valid_loss and root_mean_squared_error. The first 2 are pretty self-explanatory, however, I am not sure what the last metric is calculated on. Help, please. Thanks!
