Neural Network from Scratch in Python

[@KieCodes]

Hey Coders! 🤓 In this video, we will write our first neural net from the ground up. No external libraries needed. On the way, we will also explore the math of a neural net. And I really tried to make it understandable, even if you don't consider yourself a math genius. Please let me know if this video helped you to understand NNs a little bit better. Cheers! 🥃

You nailed it once again

[@KieCodes]

Thank you! I am glad you like it.

[@StefanKastner]

This is really well done and explained. Thank you for this. The only thing that irritated and annoyed me throughout the video is the "blubb" sound when you showed an image or changes to them.

[@KieCodes]

Hey Stefan, thanks for your kind words and your feedback. I am still figuring out my style on all regards and constructive criticism is always more than welcome. So thank you again! 🙏

[@nikibowe]

I found you through your genetic algorithms video, you are an amazing teacher and you really got me excited about learning again :)

[@KieCodes]

Wow. Thank you for your kind words. Comments like yours really help me finish the next video.

You channel is so underrated, you deserve so much more subscribes ! Many thanks to your efforts, you are great !

[@KieCodes]

Thank you. 🙏

[@kaivalyapatkar9288]

This is unbelievable! So many concepts clarified in 20 minutes! Thank you so much for your efforts!

[@KieCodes]

Thank you very much! 🙂

[@komalgupta2226]

just today found you searching about genetic algorithms and fell in love with that😊. i request you to make a tutorial series about machine learning plzzzz

[@KieCodes]

I am on it. My coming videos will be about neural nets, genetic algorithms and other ML techniques. It is really an exciting topic to talk about. Thank you for your kindness! 🙏

[@NeerajGupta-ot9eq]

Ohhhh my lords... this was one of the, if not, THE BEST video on neural networks(machine learning) that I came across on this platform. I love your explanation style and the way you simplify everything... I won't lie, I had given up on Machine Learning and Artificial Intelligence because there was just sooooo much to learn at the same time. This video alone helped me reignite the fire I needed to start learning this topic with great curiosity. Thank you so much for making such an amazing video! (I'm definitely recommending this channel to all of my juniors at my college) 💜💜💜

[@KieCodes]

Oh wow. Thank you. Comments like yours keep me going. 🙏

Duuuude, you are incredible! Please dont stop researching neural networks

Hey Mike! Thank you for your kind words. 🙏 I am already working on the next one.

I don't usually write youtube comments, but i have to say that this video explained the concept so well

[@aisyjeff95]

you are amazing. your videos helped me a lot in my phd research. wish I could buy you a coffee

Great video! Best explanation I’ve come across. You’ve earned a subscriber. Keep it up!👍🏾

Thank you so much! 🙏

[@rtross]

Fascinating stuff. I'd like to learn more about the types of problems and also the types of data-structures that neural nets are suited to.

[@KieCodes]

Thanks Robert! I will try to address that. 🙂

Nice one man! Anything soon about Harmony Search algorithms?! Can't wait for more videos!

[@KieCodes]

Thank you! What do you mean by Harmony Search algorithms? Do you have any links regarding to this?

[@empowercode]

Hey! I just found your channel and subscribed, love what you're doing! I appreciate how clear and detailed your explanations are as well as the depth of knowledge you have surrounding the topic! Since I run a tech education channel as well, I love to see fellow Content Creators sharing, educating, and inspiring a large global audience. I wish you the best of luck on your KZbin Journey, can't wait to see you succeed! Your content really stands out and you've put so much thought into your videos! Cheers, happy holidays, and keep up the great work!

[@KieCodes]

Hey I am not sure what you are asking giving the timestamp. Could you elaborate?

[@AdvForTimeFrever]

I'm sorry, I got hung up on your words "given task". I was thinking, does that refer to neural network machine learning?@@KieCodes

If you have multiple layers, how do you determine what the next {forward} bias and weights are?

[@KieCodes]

What do you mean by determine?

[@deeber35]

@@KieCodes The biases for any following layers are just randomly selected, like done for layer 1?

[@crankhere9849]

Are you referring from Neural Networks, Fuzzy Logic and Genetic Algorithm: Synthesis and Applications

[@KieCodes]

Hey, no I don’t. I just googled it and found out it is a book. Maybe I should read it. Have you? Is it good?

[@crankhere9849]

@@KieCodes We have it in our syllabus, it used same logic, xor example. and few diagrams, felt like you are referring same

[@crankhere9849]

I dont like books, i just scroll on how it looks and found that.

[@KieCodes]

No. XOR is just very very common example to explain the linear separation problem. I learned that example from Andrew Ng, maybe he read that book. 😅

whats the next video after this?

[@KieCodes]

Thats a good question …

[@Thebibleauthority]

Thanks for the video. Im new to python, but not to programming and ai, but I just want to throw this in, I don’t think that neural networks work at all like real neurons, why do I say that, because we humans don’t spend hours and hours learning what an object is, we see it once and that’s it. that’s it.

[@KieCodes]

Humans have a better training algorithm.

[@cristianhenriquez1355]

But how do you explain we don't know how to walk when we are born '-'

[@Thebibleauthority]

@@cristianhenriquez1355 Well, we learn, but what i m saying is that we don’t learn the way neural networks learn, because we can feel the data, computers cannot, we also don’t need to see millions of images to know what a face is, or we don’t need to see millions of people walking to learn how to walk, we also learn how to do things in different ways, one person will learn something, but not do it exactly like the other person, and we are always learning and no one is training us.
