WebNov 3, 2024 · Cross-validation methods. Briefly, cross-validation algorithms can be summarized as follow: Reserve a small sample of the data set. Build (or train) the model using the remaining part of the data set. Test the effectiveness of the model on the the reserved sample of the data set. If the model works well on the test data set, then it’s good. WebSep 3, 2024 · The RMSE turns out to be 2.4324. How to Interpret RMSE. RMSE is a useful way to see how well a model is able to fit a dataset. The larger the RMSE, the larger the difference between the predicted and observed values, which means the worse a model fits the data. Conversely, the smaller the RMSE, the better a model is able to fit the data.
