I would highly recommend this MOOC to anyone who is interested in machine learning. Every week consists of two lectures (each an hour long) and a problem set of 10 questions. The duration of lectures seem to be long in number only but once you start listening to it it just flies because the professor has super style of breaking complex this into simple ones . Prof Yaser beautifully explains each and every concept in depth that even some who is new to this field like me, will enjoy the course. Also this is one of the very few courses which has a very active discussion forum with great TAs, community TAs and fellow students. More than all, the Professor himself participates very actively in responding to questions which is very kind of him.
Overall I would say that the learning experience was extraordinary and definitely worth the time.
