I can see that the number of folds (cv=5) is reflected in the corresponding columns in the cv_results matrix.
I am wondering if there is also a relation between the number of iterations (n_iter = 200) and the number of rows (# = 500) in the cv_results matrix presented in the demo notebook…
It seems that the information provided in both the video and the notebook are incorrect. The file randomized_search_results.csv was actually computed using n_iter = 500 i.e., the same as the number of rows.
Thank you for noticing this error!
