This course explores the concepts and algorithms at the foundation of modern artificial intelligence, diving into the ideas that give rise to technologies like game-playing engines, handwriting recognition, and machine translation. Through hands-on projects, students gain exposure to the theory behind graph search algorithms, classification, optimization, reinforcement learning, and other topics in artificial intelligence and machine learning as they incorporate them into their own Python programs. By course's end, students emerge with experience in libraries for machine learning as well as knowledge of artificial intelligence principles that enable them to design intelligent systems of their own.

This guy talked non stop for 1.5 hours. THANK YOU

[mehuljain]

the world is being beaten with lockdowns and a virus and yet you guys delivered world class content for free for everyone to learn. LEGENDS!

[k.h.p.]

I'm three years late to this 2020 lecture, but never too late to say, "thank you!"

[eugeniar]

Opened on YouTube just to say THANK YOU for such a detailed and clear explanation!

[vijaynyaya]

In my opinion, Brian is one of the most sophisticated persons on CS50.

[Hoobz]

As an older bloke who has done carpentry his whole life, I'd like to say how excellent Brian was in this lecture.

Made everything easy to understand, while explaining quite a lot in a limited time.

Not one "Ummm" or "Ahhh". Spoke incredibly clearly.

Thanks for the effort made to help even a bloke like me be able to follow along.

[ml_serenity]

I am in awe how these seemingly very young lecturers in CS50 are so damn good! It's a pure joy watching these lectures even for someone who is an expert in the field for many years already. Thanks so much for free quality education for young people all over the world!

[dhanyams]

This is the best presentation i ever watched in my entire acadamic life... Very well explained and good quality of contents. Thank you for such a useful video.

[BlueWizardsII]

Excellent lecture. Clear, concise and 'relatively' easy to follow. The great thing about recorded video lectures is that one can pause, rewind, review, very unlike sitting in the lecture hall live.

[rfdickerson]

Brian is an incredible lecturer. He is wicked smart and able to explain things so crystal clear and so engaging. He will go far in life!

[OsamabinBiden]

As someone who plays chess and has used the engine multiple times. This was refreshing to see

[photoniko]

I'm starting the course, and I really liked the clear and easy to understand explanation, it even seems easy with Brian's explanation.. Now I've been testing the maze in Python and playing with the text files... I'm amazed with this. ..

[ahmadkathrada]

Just listening to this video gave my life so much meaning. If I see you one day Brian, imma treat you to my mamas chicken curry which is the curry of champions. Champion is what you are!

[jinalvyas]

Mr. Brian, your way of explanation makes the process of understanding complex concepts, a cakewalk for us! Thank you so much!! Keep up the good work, all the best!!!

[oGiuseppeDonato]

I just wish to thank him for his ability to explain with clarity and enthusiasm concepts that glue me to the screen. Thankyou.

[acidtears]

You're going to do great things Brian! Thank you for this incredible lecture series. This is genuinely better than the Data Structures & AI course I took at Maastricht University... Goes to show how much of a difference passion & presentation skills can make :)

[GrowthMindsetGlobal]

What an amazing way to explain the complex subject in such a easy and explanatory way. Hats off to you man.

[noobieexplorer]

One of the problem set related to this lecture is unbeatable tictactoe which was a really hard problem. The reason is that I was coming straight out of cs50 to do this course. But this course requires some good understanding of objects and classes which was not provided in cs50 intro course.
I would suggest anyone trying out this course after cs50 to get some good grip on object oriented programming in python.

[maegho]

I'm applying for HARVARD'S secondary school this summer and plan on taking computer science courses while there, these videos have helped me grasp so much knowledge thank you!!

[JEEAspirant-pb]

very very great lecture with the coding part was amazing, your service to the society is really a great thing . Thank you
