Thank you for your comment, we love to hear such wonderful feedback!

[@Treegrower]

I think it's a great benefit to humanity to have this course publicly available. What an amazing resource! This definitely will get a lot of people involved in AI / ML who maybe never would have learned it otherwise. Super awesome!

[@hassanlaqrabti4036]

Thank you Stanford for spreading the knowledge across the world.

as a passionate of AI from Cameroon and not able to afford for a formal education this course is valuable for me. Thanks so much to tanford

[@germansacramento2243]

Thank you Stanford. It is amazing to see your commitment make our world better by sharing courses for free. Specially considering you are giving the opportunity to learn and a pottential better future to so many people far away / without resources that would never have the chance to learn such things otherwise.

[@stanfordonline]

Thanks so much for watching, and for taking the time to leave us this feedback!

[@jeraldgonzalez8944]

Thanks!! Stanford for the lectures I've been working understanding machine learning and neural network from MIT and the Professor Andrew Ng aswell to later move on to work on quantum machine learning with IBM.

[@waynep610]

Thank you for keeping updating the courses, Appreciate!

[@MrProgrammer-yr1ed]

Thank you Stanford for providing this course

[@tanvirhasannirob6696]

Thank you Stanford Community and Key Machine Learning Lecture One Thank you all I want the complete course of machine learning to be done like this and what feedback is given after completing the course feedback how to work how to develop like this is the most urgent need is

[@usyntest]

Lecture starts from 18:30

[@tanvirhasannirob6696]

It would have been best if there was a specific platform for this machine Learning. They are regular classes, discuss everything, practice regularly and make solutions for the tasks you have on a regular basis. This machine learning course is constantly creating a platform through online. I request you to develop the platform to launch the machine learning or deep learning course. I am Bangladeshi and a student so I am very willing and interested.

[@fawadahmad1119]

thank you stanford for this detailed course on introduction to ML. can someone please tell what should i do next after completing this?

[@kedarpaulCogitoErgoSum]

Can't wait to go though the lecture series.😊

Thanks Stanford, this is super helpful!! Where can we find the problem sets?

[@azizamanaaa6006]

Thank you very much Stanford for this valuable course and we all know the value of this course so thank you very much. I have some questions is this course recent and how much time it will take to complete this course

[@stanfordonline]

Thanks for your questions! This course was recorded Spring Quarter of 2022. The time to complete this course varies, however graduate students enrolled in this course typically spend 10 weeks, 15-25 hrs/week. Hope this helps!

[@SpeaksYourWord]

​@@stanfordonlinegraduate students? Can I take it as an 2nd year CS undergrad? I'm fairly good with maths.

[@fayezalhussein7115]

[@girikkhullar4072]

Thanks Stanford for sharing this lecture. If you don't mind me asking, how soon can we expect the next lectures to come?

[@stanfordonline]

Hi there, thanks for your question and for watching! We will publish one new lecture per day for the next few weeks. The entire course will be available to view before the end of the month (August 2023).

[@vancouverrrr]

any significant changes compared to the 2018 Andrew Ng course? i find this one easier to follow

[@SomeTenth]

I would like to know the same. Which one to follow.

[@QQ_te]

have you gotten the answer for that?🙏

[@rewu858]

Well you should follow the most recent one as AI and machine learning evolves really quickly. This one is from 2022, a lot has happened in two years so you can already consider its partially outdated, still its very great content and a unique chance for everyone in the world to get access to that kind of high-level education.

[@yaserheba7471]

Where can I find the problem set and the code of these lectures ?

[@user-7tgfyfuyd0dty]

What are prerequisites for these lectures?

[@audiophile...]

7:06

[@stanfordonline]

Thanks for your question! Prerequisites for CS229 - Students are expected to have the following background: Knowledge of basic computer science principles and skills, at a level sufficient to write a reasonably non-trivial computer program in Python/NumPy. (CS106A or CS106B, CS106X.) Familiarity with probability theory. (CS 109, MATH151, or STATS 116) Familiarity with multivariable calculus and linear algebra (relevant classes include, but not limited to MATH 51, MATH 104, MATH 113, CS 205, CME 100.) You can find more information on the course website: cs229.stanford.edu/syllabus-spring2022.html

[@moemoe-jb2fw]

If I don’t know multivariable calculus and linear algebra then learning ml is not possible ?

[@lugia8888]

Multivariable calculus: treat other variables as constant when taking derivative/integral. Linear algebra: manipulate matrices and learn about vector spaces and bases. Not much to learn so yes is possible

[@vmsikrsnah]

Where can I access the PPT used by the professor

[@Rustincohle88]

Focus on classes instead of looking comments LoL
