A friendly introduction to Deep Learning and Neural Networks

A friendly introduction to neural networks and deep learning.

For a code implementation, check out this repo

This is a follow up to the Introduction to Machine Learning video.

Note: In this tutorial I use natural logarithms. If you used logarithms base 10, you may get different answers that I got, although at the end it doesn't matter, since using a different base for the logarithm just scales all the logarithms by a constant.

dear sweet baby jesus. You just gave my brain a breakthrough, this is probably the best introductory course on Neural Nets on the internet. Thank you Luis!

"But then I saw a real neural network and realized it was much scarier than that."
Okay, bonus points

[eshnakaul]

why did I not find this video before!!! this is amazing, Luis. You are clearly a very talented teacher, thank you so much. Omg those Stanford and MIT lectures are making so much more sense.

This is BY FAR the best explanation of ANY topic that I've ever seen. A true talent. Thank you so much for this!

[PasinduTennageprofile]

Really awesome presentation !! Clearly describes the core methodology of Neural Networks

[ammarahmadawan]

The best 30 mins that I have spent in my life :-) Thank you for explaining such scary functions and terminologies in such a simple way!!

[FarhanArshad]

I am at the loss of words to describe how helpful it was to understand the basics of neural networks. For me, neural networks are not scary anymore. Thank You!

[siddharthadas]

What an amazingly intuitive explanation. Thank you Luis Serrano!

[fishmightfly]

This was so unbelievably awesome thank you. I've been struggling to understand this stuff for months and your video made it completely obvious. Thank you!!

[AbhishekSachans]

It has really boosted my interest in deep machine learning. Thanks!

[flwi]

Wow, that‘s one of the best explanations of that topic I‘ve watched so far. Very well done!

[sophiasan]

You are really gifted at breaking down complex concepts into an easily understood analogy. That is a gift not many have. Keep up the amazing work!

[williamikennanwosu]

You have explained so many foundational insights and distilled multiple concepts in deep learning and artificial neural networks all in one video of just around half an hour. You are amazing. I feel like have a unique perspective on deep learning now and can grasp higher concepts. Thank you Luis.

[joevijay]

Most friendliest explanation of neural networks I have seen in youtube, so far.

[heenamadaan]

seriously. it ws the best video ever explaining neural networks with visualization in such simplified way.

[amitbangera]

I reserved my first comment on Youtube for something like this. I second my thoughts with Joao Sauer. This a testimony to how human mind is still the most intelligent computer that could help translate a complicated subject to a simple model. Thanks Luis Serrano. This is very helpful. Appreciate your effort in putting this together.

[prabhatgautam]

This lit up some neural pathways in my brain. Thank you for explaining with so much clarity and sharing knowledge with us.

[MaxIme]

Clear and simple, I'll check you convolutional neural networks video next. Great work!

[j.helenyang]

Clearly from someone who understands it deeply. Thank you so much Luis for sharing.
