I took it relatively recently but I have mixed feelings about it. While the topic itself is very interesting and they have some interesting exercises, the explanations in the videos are seriously lacking.

There are big jumps in reasoning and explanations so you'll need to rely on external material quite a bit (I've used Bayesian Reasoning by Barber) Also, exercises are presented in Matlab/Octave which makes them a pain to work with.

After completing the specialization, I've almost felt that you could just do a course that explains this course.
