Create a Simple Neural Network in Python from Scratch

In this video I'll show you how an artificial neural network works, and how to make one yourself in Python. In the next video we'll make one that is usable, but if you want, that code can already be found on github. I recommend watching at 1.5x speed, unless you're coding along.

Coding starts at 2:30

In the next video we’re going to be making a blockchain in JavaScript, so subscribe if you’re interested in that stuff!

"stay with me, it's gonna be ok"... dude, that's such a lovely sentiment. You were born to teach I think, with that ability to keep pupils onboard. Very good video my man, thank you so much..

“Stay with me, it’s gonna be okay” that makes me feel like I’m actually learning something and not just being told something

What the?....this is it, finally I found good tutorial

My friend, your explanation in 15 minutes gave more clarity to me than hours of crash course tutorials online. So simple and well explained. Awesome stuff my man!

After watching hyper-advanced tensorflow/keras stock market prediction tutorials for a while, being completely lost, I stumbled on this.
I finally, after weeks of trying to learn NN and decades of practical programming experience, understand it.

The iterative backpedaling was what confused me with all of those other videos, but taken down to its most simple form, like in this video, I can now see that it's merely looking at what it got, what it was trying to get and make adjustments to the appropriate synapses based on that, then trying again.

It's not the maths that confused me, it's how the machine actually learned. And that was perfectly demonstrated in this video. Thank you!

"stay with me it's gonna be okay" <3

Finally, a clear, straightforward tutorial to code along. GREAT JOB!

This tutorial is a perfect blend of talking/programming and slides. Its also quick and to the point 8)

Most useful video on the internet for a total beginner, for anyone new to AI. Thanks.

[paulschmidt]

Bro, it was much easier then I thought. Thx for explaining.

[Oleg-kkxv]

Thank you very much. I constantly see these videos about the theory of Machine Learning and AI but I have never found an in-depth start from scratch tutorial with mo libraries, all while explaining everything. Thank you!

[joesminis]

At the 10 minute mark and I just wanted to say that your explanations are clicking left and right with me thank you!!!!

[Awesomer]

What a fantastic way of explaining it. Whilst this is obviously not immediately useful, It's a sort of toy approach that gives you a building block to understand the greater scope.

[abdechafineji]

The best one who can give you the right explanation of creating of a neural network from scratch.

[MsRAJDIP]

So far the best simplest and practical tutorial I got. U cleared all my doubt and little background in python helped me lot.

[aaronisinjapan]

Wow, I’ve been looking for a tutorial just like this for a long time! Subscribed! Please keep making videos!!

[hdluktv]

I watched a lot of videos about Machine Learning because I wanted to unterstand how that works. Non of these Videos explained so good like yours how a neuron and the adjustment actually works. Good work, now I finally understood it.

[chessprogramming]

Man, this was so to the point! Thanks for your efforts. Best NN basics tutorial I've found so far! Very very useful!

[deanresin]

This was a such a great tutorial. Very clear, concise and well paced.
