WebAug 26, 2024 · The average squared error for the predictions is 91.14, which can be used as a baseline to see if model accuracy improves over time or not. In order to truly interpret model accuracy, we should look at alternative metrics such as RMSE or MAE. Regression metrics Metric comparisons MSE vs MAE, which is the better regression metric?
