Solution
The purpose of evaluating the model's performance in each iteration of K-Fold Cross-Validation is:
-
To determine the optimal hyperparameters for the model: By evaluating the model's performance in each iteration, we can identify which hyperparameters yield the best results. This helps in tuning the model to achieve optimal performance.
-
To measure the model's accuracy on the training data: Each fold in K-Fold Cross-Validation involves training the model on a portion of the data and then testing it on the remaining data. This allows us to measure how accurately the model can predict the output for the training data.
-
To assess how well the model generalizes to unseen data: By testing the model on different subsets of the data in each iteration, we can get an idea of how well the model will perform on new, unseen data. This is crucial for understanding the model's predictive power.
-
To compute the average score for the model: After evaluating the model's performance in each iteration, we can compute the average score. This gives us a more robust measure of the model's performance, as it takes into account the variability in the model's performance across different subsets of the data.
