Giving your videos pertinent titles like for example in this case: "Cost function regularization" would not only make your videos easier and more pleasant to navigate, they would make the YouTube algorithm direct a lot more traffic to you.

I have a question: why is the regularization term divided by m (that stands for number of rows), instead of n (that stands for number of columns) since we are summing w-squared values for all columns (variables), wouldn't it be more appropriate to divide by number of columns to get the average for all columns? if the data has say 20000 rows (m=20k), and not more than say 200 columns (n=200), the regularization term will end up being an insignificantly small value because of division by m instead of n. Can anyone please clarify. Thanks.
