WebFeb 24, 2024 · Step 1: Split the data into train and test sets and evaluate the model’s performance. The first step involves partitioning our dataset and evaluating the partitions. The output measure of accuracy obtained on the first partitioning is noted. Figure 7: Step 1 of cross-validation partitioning of the dataset. WebMay 26, 2024 · Model development is generally a two-stage process. The first stage is training and validation, during which you apply algorithms to data for which you know the outcomes to uncover patterns between its features and the target variable.
