Some of the subjects were a bit long for my taste, but I think that's because I already knew them.

5 / 5
The course is very well designed, combining clear theory with well-structured practical exercises. The practical exercises are particularly useful for applying the concepts learned, and illustrate in concrete terms the advantages, such as improved performance, as well as the possible disadvantages, such as the complexity or limitations of certain approaches.
