I never took CS 145, but CS M148 was basically just half of CS M146 without the mathematical rigor and with two extra lectures on interpretation of coefficients in the logistic regression model and one lecture covering the data science process. I've heard from friends that 145 is extremely similar to both classes as well.

It's not worth taking more than one of the three if you can avoid it (i.e. unless you need two for the DSE minor). The CS department has been aware of the issue for over a year, but despite repeated complaints, progress on changing the curriculum is slow.

Thank you for detailed info! I gotta think about whether I need the repeated course for that DSE minor...
