What is convolution? If you've found yourself asking that question to no avail, this video is for you! Minimum maths, maximum intuition here to really help you understand the idea behind this complex topic.

What convolution really is: "when you convolve two functions, you're basically combining them in such a way that tracks their interaction throughout time". I guess that is a gist of the video.

The issue with that sentence is that it would be equally true if the integrands were S(x)*f(x+t) or just S(x)*f(x). Just “Interaction” is too vague to describe what it is.

Physics student here. I'm in third course and I've been using convulations now for over a year without fully understanding what they meant. That has changed now. Amazing explanation. Loved the analogies.

Electrical engineer here who graduated nearly 7 years ago, and I've somehow slipped through without properly understanding convolution. 1st Year EE was "you'll learn this next year" and 2nd Year EE was "you should have learnt this last year", and somewhere in between I never bothered to learn it myself after looking at the maths and shoving it in the too-hard and not needed for power engineering basket. This is the first time I feel like I've properly understood convolution, at least intuitively, and now looking back at the maths on Wikipedia, it makes a lot more sense now. Thank you!

Mathematicians should learn how to turn to intuition. You just saved me hours of work trying to understand convolution, when it was literally one slide in my theory for convolutional networks.

This is why yourube was invented. For awesome explanations and proper teaching. We can now filter out the bad tutors who have no understanding of what they are teaching! I got a load of professors who just regurgitated the text books without explaining any of the intuition on what was really happening. In hind sight, they probably didn't understand it themselves! This is where we can revolutionise education.
