Hello All,
My name is Aman and I am a data scientist. In this video I explain gradient descent piece by piece. In this video, my intention is to make gradient descent extremely simple to understand. Gradient descent being a very important algorithm for machine learning and deep learning is a must know topic for every data scientist. Below questions are answered in this video:
1. What is gradient descent?
2. How gradient descent works?
3. Gradient descent algorithm?
4. What is gradient descent in machine learning?
5. What is gradient descent in deep learning?
6. How gradient descent algorithm works?
About Unfold Data science: This channel is to help people understand basics of data science through simple examples in easy way. Anybody without having prior knowledge of computer programming or statistics or machine learning and artificial intelligence can get an understanding of data science at high level through this channel. The videos uploaded will not be very technical in nature and hence it can be easily grasped by viewers from different background as well.

My question is when we calculate Partial derivative with respect to 'c' and 'm' ,we should consider one as constant.For example
to calculate partial derivative of cost function J with respect to c ∂J/∂c ,we should consider 'm' as constant .So the above calculation should be like this. -2[2 - (c+m)] + (-2)[4-(c+3m)] => -2[2-(c)]+(-2)[4-(c)] => -2[2] -2[4] =>-4-8=> -12.
Please confirm
Yep when we calculate w.r.t c m is const and vice versa.
Hi Anjani...why it is -2[2-(c+m)] as derivative od [2-(c+m.1)]^2 . dont you think it should be 2[2-(c+m)] from the derivation rule.
why -2 i still didnt get it... it should be ... 2[2-(c)]+2[4-(c)] right?
Could you please elaborate on your derivative method @Anjani Kumar . I guess the value -4 in the video is correct
Why -2?
I like how you simply talk and explain .Especially, your speed is enough for everyone to understand such a tough concept like gradient descent.
the info you have given at arount 7:00 was very insightful. it shows why gradient always points in the direction of steepest ascent. thank you
You're just amazing! Anyone can understand gradient descend by watching this video. Thanks!
great ... simple and best. Thank you.
Great explanation. Thank you for this.
Why do I understood everything... Thankyou so much sir ❤️❤️❤️❤️❤️.
Great explanation
Thank you. You make me understand this.
Awesome explanation Sir!! Great work!!
Hi Aman sir, i am a PhD scholar (almost completed) from IIT Madras and since last few months just for my interest i was exploring DS, ML and DL (though i am not from CS background) and landed with some of your videos on UDS which really increase my curiosity to learn more about it. Though i have explored a lot online videos and many other sources on ML including corsera etc. but i can say that your explanations are extremely good for conceptually to understand the subject. Just i am not able to control myself without appreciating your great effort and you are doing really a great job/help for the aspirants of ML/DS. Thank a lot for all what you are doing.
Your comments are my motivation Brij. Thanks a lot.
Thanks for your feedback

So nice of you Akash. Pls share in Data Science groups if possible.
Great great lecture for gradient descent I have ever seen....thank u so much for sharing ur knowledge sir ❤️
So nice of you Mani. your comments mean a lot.
This is one of the best explanation video about Gradient Descent, I like your detailed explaination. Looking forward for more videos on various Optimizers.
Thank you
Thanks a lot Bala. Yes will create on those topics as well.
Amazing man
Simply wow. After a month I understood today Gradient Descent. Thank you soo much for the video 😊
Welcome Himanshi. Means a lot to me.
Greate man 👍 👌 💛
Good Explanation !!!!
Sir you are great!!
V Good :)
This is just amazing.... simple explanation of a complex thing.
