Which ML courses to take in Summer sessions

Hello everyone,

I first want to thank the entire team for the testing sessions you offer! I particularily appriciate them !

I want to take a Summer Session next summer (2 or 3 months in 2023) in Berkeley, Stanford or Columbia. As far as I know, these are the only big US universities proposing summer sessions :

Berkeley : https://summer.berkeley.edu/
Stanford : https://summer.stanford.edu/courses/course-list
Columbia : https://summer.sps.columbia.edu/courses/summer-courses
What summer session Machine learning courses do you advise me to take to be continuous with the Machine Learning specialization I took ?

Thanks a lot !
Have a good time!
Erwan DAVID
