    I just came from Andrew Ng's ML course in order to understand SVMs better. I found something quite interesting. Andrew gets the optimization criterion at 21:49 from an altogether different place. He arrives at SVMs by modifying the logistic regression's cost function, and the optimization criterion emerges from the regularization portion of the cost function. He then explains why that leads to a maximum margin. In contrast, this professor starts by obtaining the margin width algebraically with the intention of maximizing it, and then explains why that leads to separating data.
    Pretty cool.

    What a gem of an lecture, Trying to understand equations directly just makes you mug up somethings and like you never understand it fully. What I found is that when you actually run yourself through a simulation of what the inventor of the equation did and follow the footsteps than things start making sense eventually and you arrive at solution and you think huh that wasn't to hard. Rest in Peace Prof Patrick Winston world needs more professors like you really man. This is first video lecture of his I am watching and I can feel what a great man we lost!!

    This professor is very, very well spoken when it comes to explaining SVM's. Clear, concise, focused on one instance of one issue at a time... Many professors try to show you the entirety of the math while walking you through the conceptual ideas and it makes SVM's very difficult to learn! This man is quite the opposite! Great work! (And by math I didn't mean just showing the margins, graphs etc.. meant proof of the equations which two of my professors did in two separate machine learning/data science classes.)

I do teach math myself and I deeply admire how he boils it down to the essentials without leaving anything important out. Just looking at how little there is on each board and how clearly the beauty of the subject shines through ... a true master class. And I always thought we should teach more math history, so it is great to hear from him how the ideas actually developed.

      what do you expect? this is the difference between going to MIT and going everywhere else. It's not the knowledge that's the difference. It's how the teachers are able to relate the material in a very palatable fashion, that's the difference. I sometimes rue in my old age what I missed (because I didn't go to a good school) because i see the difference in my own understanding of things compared to those that went to good schools. It's not that I am not capable of understanding. It's that they have an in-depth grasp of the material because they sat under the tutilage of people like this professor. That's the difference between MIT and coursera or any other school folks.

    @krakenmetzger 4 года назад +19

    Note for myself and others: the reason in English why (dL / dw)[(1/2) |w|^2] = w is because dL/dw is a directional derivative. Equivalently, we are rotating the coordinate system such that the w direction is an axis, and taking the partial derivative with respect to w. We can now treat |w|^2 just like x^2 if we're doing normal calculus, particularly because |x|^2 = x^2 for all x.

    Thought I would add to the voices of approval.
    I've just completed an elementary Machine Learning course (SVM wasn't on it), and have watched quite a few youtube videos, including those from Andrew Ng.
    The clarity of language, display, sequence of demonstration and speed of this lesson are absolutely spot on.
    Thanks !

    genius explanation here. very simple to understand, I love digging into the underlining mathematics thats involved with these algorithms. The idea that a kernel function can transform the nonlinear inseparable data into a higher dimensional space that is linear is simple mind boggling to me. So cool of a concept and really simple to realize once you get the mathematics behind it.
