It just needs more videos to get rocket growth !! Very Good Quality stuff ..

[@rvan9154]

HOLYYYYY GWAKAMOLE !!!! I really wish I came across your video much before I took the painful ways to learn all this… definitely a big recommendation for all the people I know who just started with optimization courses. Great work !!!!!

[@djhiploza731]

This is so high quality stuff! Thanks for the graphical explanation at the beginning!

[@namansharma9852]

Hi Ahmad! A big thank you from India. I am an engineer in material science from last 6 years and never learnt any programming language to be frank and today I am starting my Python journey in a quest to enter in to the field of machine learning and artificial intelligence for simulation of advanced materials. You have made this course super easy for the zero beginners like me. Hopefully I will complete this course and then will proceed to Python mastery course. And happy teacher's day.

[@PROGAMER-og7xv]

Great content

[@kartalgaming8928]

This course has literally changed my life. 2 years ago i started learning optimization from this course and convex optimization from Ahmad's famous course and now i am a research scientist at a great research institute. Thanks Ahmad♥️

[@angryprashnepal1593]

Amazing explaination! This is very helful for understanding. Thanks a lot sir.

[@Aysenurcaaa]

Loved the graphical presentation

[@samarendradash6459]

WoW! This is amasing work man, thank you.

[@twobros7906]

Thank you Ahmad for this amazing tutorial video you have made. I am a researcher and work on large datasets. Basically, I am a wet lab scientist but really want to python to write different codes that will help me analyze the huge dataset. When I started working with large datasets I did all the calculations and sorted the data manually which is so labor intensive. Therefore, python will certainly help me in minimizing my efforts and provide more robust data analysis power.

[@AllAboutDima]

you are tooo much underrated :(

[@lyrex2193]

Excellent video. I especially liked how you linked it back to the root finding version we learned in school. My one beef with this video is that that's an unfair depiction of Tuco.

After 2.5 years, I am returning here to say that I’ve just accepted a job offer for a good salary, and my IT journey started here, from this video, in November of 2019. This was my first source of information, when I got back from work (being a cable tech), and typed “Python full course” or something along those lines. Of course, back then, a lot of concepts like classes and inheritance meant nothing to me, and this video perhaps wasn’t the most beginner friendly. However, I was so sick of my job and I absolutely saw no growth in doing cable, where the salary cap for a technician was probably IT jobs base pay for the most part, so I decided to Google every single thing I don’t understand. And I successfully changed careers.

[@sysaa]

Thank you for the words of encouragement, I appreciate it!

[@beyazhacker3755]

Crystal clear explanation, thank you!

[@youssef3096]

Brillant explanation, thank you so much.

[@pr0d1gy32]

Gorgeous tutorial ! I have never even saw the pyhton interface in my life before, but with the help of your videos i feel like i understand a lot. Also, when you let us try with the 'homework' that`s where the experience shows. my code is always longer and less intuitive. also, i seem to opt for the input command a lot more. something about interracting with the code always gets me !

[@GLiveStreamVoice]

I love this video, I feel so privileged to be growing up in an era where knowledge is so easily available, Ahmad is really helping to improve my and many other's opportunities.

[@mustafasamet2783]

This is brilliant thank you, hope you give us more visual insight into calculus related things

[@abdurezzakessekoglu9864]

This is great.

[@_modlim6569]

It's rare when less viewed video gives best explanation. Your presentations are almost like 3Blue1Brown or Khan academy! Don't know why this video has this less view!!

[@twitchclass3128]

This was such an awesome explanation, so grateful thank you.

[@GAMEXYZ]

Great video man. God bless you

[@iredikstr8606]

Hello, great video. I am currently following a course on non-linear optimization and I would like to make videos like this for my own problems. I'm a visual learner and this video is exactly what I'm looking for! Great content!

[@gulseherbayrak2570]

Amazingly presented, thank you.

[@gamefilmfreak4495]

oh man is this gold

[@tiyas5188]

Awesome, thank you!

[@acousticankush7623]

Hi Ahmad. Thank you so much for putting this together. I’m wanting to learn python because I’m a teacher with an IT background who wants to find a way to make simple web applications to make life easier for my fellow teachers. I’m mostly interested in creating a way for teachers to enter data (assessment data, house points etc), which can then be collated, summarised and displayed in useful ways.

[@theknan6800]

Good job. I am subscribing !

[@diyonex-sosyalicerikplatfo3591]

Thank you for your amazing comment :-)

[@franklincomedy]

Yayy!

[@LyonelAchilles]

Amazing job! Thanks a lot!!

[@-ahmedmohamed1739]

amazing

[@valkx1808]

Thanks a lot 😊

[@relaxandsleep7567]

Sure. Consider the quadratic approximation f(x) ~ f(xk) + f'(xk) (x - xk) + 1/2 f''(xk) (x-xk)^2 at the bottom of the screen at 7:06. To minimize the right hand side, we can take the derivative with respect to x and set it to zero (i.e., f'(xk) + f''(xk) (x - xk) = 0). If you solve for x, you get x = xk - 1 / f''(xk) * f'(xk).

[@PubgMobile-ve7ij]

Another problem is for a negative curvature, the method climbs uphill. E.g. ML Loss functions tend to have a lot of saddle points, which attract the method, so gradient descent is used, because it can find the direction down from the saddle

[@malanumtvph4966]

can someone please tell me whats the algebra needed for getting the newton method from the taylor series stated in 6:58. thank you in advance

[@chandorasaab3323]

Hey can you do a sum of square, dsos optimization tutorial for post graduate student.

[@memmedov-emin7852]

What is the plotting tool you are using?

[@قناةأناوأنا]

Or did you mean i.e. an abbreviation for 'that is'.

Who do you think is the created scientist who ever lived?

I have explained this in another comment. Let me paste it here:
