The Essential Main Ideas of Neural Networks

[@statquest]

The full Neural Networks playlist, from the basics to deep learning, is here: kzbin.info/www/bejne/eaKyl5xqZrGZetk Support StatQuest by buying my book The StatQuest Illustrated Guide to Machine Learning or a Study Guide or Merch!!! statquest.org/statquest-store/ NOTE: A lot of people ask where the values on each connection come from that we use to multiply and add to the inputs. This question is answered at 3:48 - in short, they are found using a method called Backpropagation.

@@yashaswikulshreshtha1588 what is wrong with you? The math presented is NOT difficult, it is literally basic calculus. Yes, we do understand the math. If you are struggling with this, I recommend that you retake calculus and algebra then come back here once you have a good foundation. None of this will make sense if your math knowledge is weak.

I am a professor in computer science, and did my dissertation on Bayesian methods in AI, and I will say that this is the best explanation of neural networks I have ever seen. It does no hand-waving, and makes no assumptions about the viewer's math skills. Coming late to the CS party in my 20s, and not being from a strong math background, I can really appreciate this approach. I will be using this video series in my Intelligent Systems class. Thank you.

For Christ sake, this guy is brilliant! Taking something very intimidating and showing how it works is worth gold. I am embarrassed to say that I am a scientist, have been for over 20 years. We over complicate and write papers to sound smart, but really never really say anything. And good luck ever trying to reproduce those results in the paper. This is how technology and science should be taught and discussed with our peers.

[@DrRiq]

I think the novel value of this video (for me) is that it helps bridge the gap left with 3Blue1Brown's video where he intuites what the NN may be doing, but then reveals that it actually appears random and chaotic, without the sense of order we initially assumed to make sense of it. This video explains that although the particular weights and biases may appear random at first glance, it is through their summation/cancellation that an order emerges. Also, kudos for introducing a new beginner example -- I genuinely did not realise that there were other applications outside of image recognition lol (I am a beginner to this!). As in, yes it's easy for us to look at the simple data and say 'hurr durr why not just model it with a quadratic equation'; but here is a different way to derive values to fit the data on the graph. Which was new to me, so, thanks!

[@statquest]

To those of you who is still considering whether to watch this tutorial or not. This tutorial is well explained, there is nothing but benefits in seeing this it. As the lecture already says in the beginning of the video, he is simplifying the "hard" terminologies and mathematical notations. He is even emphasising the important part by saying BAM, double BAM and triple BAM which is actually a kind of energy boost since it is funny. This is my third time watching this tutorial, first time was to get general understanding of the topic, second time to apply the mathematical knowledge. This time I'll apply the mathematical knowledge and code an algorithm from scratch. Wish me luck. Lastly, thanks for the tutorials.
