WebSep 29, 2024 · Grid search is a technique for tuning hyperparameter that may facilitate build a model and evaluate a model for every combination of algorithms parameters per grid. We might use 10 fold cross-validation to search the best value for that tuning hyperparameter. Parameters like in decision criterion, max_depth, min_sample_split, etc. WebGrid search involves taking n equally spaced points in each interval of the form [ ai, bi] including ai and bi. This creates a total of nm possible grid points to check. Finally, once …
