Mokarrom , ideally not as such but let me tell you something before starting Machine Learning using my playlists. There are broadly 2 ways to study Machine Learning ... Approach_1: Conventional_method i.e. To learn basic fundamentals first, do the courses which provide the complete overview then try to find solutions of the existing problems Approach_2: Reverse engineering method i.e. First understand the problem, try to solve it and if solution is possible through AI then whatever come across to solve the problem, keep learning that Though both the approaches have their pros and cons. I have tried to explain concepts with both , like for some concepts(or algorithms), first I have discussed theory & then shown projects or practical implementation and for some first shown some usecases or applications & then went with intuition & MATHS part behind the algorithm, so if you are comfortable with this way of teaching-learning process, surely you will not have much problem (if you have knowledge in Fundamentals of MATLAB , Calculus , Probability , vector space , then the road will be much more smoother in learning this domain ,although no worries if you don't have , I have tried to explain from scratch). And any doubt you can ask in the comment section anytime :-) Hope this will help you. Happy Learning :-)
