The following links are extremely well done visualizations which cover the important machine learning concepts. I highly recommend you check it out. In fact, they are the best visualizations of machine learning concepts on the web:
Here is another video by Luis Serrano, one of the course developers of Udacity Machine Learning Engineer Nanodegree. Must watch for beginners, and a helpful review if you have just learnt the core machine learning concepts.
I hope the above provided you a lot of intuition and a clearer big picture review of the main concepts in machine learning.
