A brief explanation of the Transformer Architecture used in GPT-3, ChatGPT for language modelling. (Uploaded here, for those who missed class due to the unusually nice weather :-) )
On the Importance of Deconstruction in Machine Learning Research
Просмотров 7 тыс.3 года назад
This is a talk I gave in December 2020 at the NeurIPS Retrospective Workshop. I explain why it is so important to carefully analyze your own research contributions through the story of 3 recent publications from my research group at Cornell University. In all three cases did we first invent something far more complicated, only to realize that the gains could be attributed to something far simpl...

In-class Kaggle Competition in less than 5 Minutes
Просмотров 12 тыс.5 лет назад
The Fall 2018 version of CS4780 featured an in-class Kaggle competition. The stuents had 3 weeks to beat my submission, for which I only had 5 minutes. Some students challenged me to show a screencast of me actually training and uploading the model in time, so here you go. Happy Xmas.

Note, however, that eCornell does charge tuition for this version.

Kilian is amazing
you are like a gift from Nature <3 .
Goat prof
5:57 - boundary point can be assigned to any one group. but it may change if we restart the dbscan model. does it affect the model?
Yes, it depends on the order in which we start. That's OK though. After all there isn't a true answer and other algorithms (e.g. K-means) are even more initialization dependent.

This is cool!
Amazing lecture.
34:52 very interesting point!
👍
I will start my machine learning journey, I have the knowledge of stat , calculus, linear algebra.Should I follow this series?. From comments it seems this is a very very good lecture series. Or this would be too advance for a newbie like me?
Yes, definitely. Good luck!
@kilianweinberger698 thank you professor for assuring.
At 39:53 the example seems a little bit off to me. I would expect Newton's method to converge in a single step (the function looks like a quadratic).
The second order Taylor's approximation gives the polynomial equation of the parabola that approximates the function at a point .Here the function is the small parabola and the approximation is the other wider parabola, Newton's method minimises the wider parabola, that's why it will just shoot off in a single step
@leviiida9967 Doesn't the approximation looks a bit off? I understand the purpose of the drawing, i.e. that we bounce back and forth. It just felt "too contrived", that is if we construct the second order approximation it would be steeper.
👍
👍
compression comparison for cross entropy is just damn good....
Thanks a lot. Wished I could have attended 'ML for Data Science' as well
Thank you Professor !!!

Thank you Sir !!!
Thanks a lot !!
Thank you !!
Thanks a lot !!
Thanks a lot Sir !!
Thanks !!!
Thanks !!!
Thank you Professor !!!
The time watching these lectures passes in no time !! Thanks, Professor!
Thank you for the amazing Lecture !!!
Thank you so much Sir !!!
He is a fantastic teacher. And all the energetic teaching has given him a bad throat.
I like your way of teaching more than Andrew or anyone else, cause they assume students or anyone watching is at least tiny intelligent, which just isnt the case. After all we are all just stupid, except for few people, or that one kid in class
And here i am rewatching this for the 3-th time, cause i didnt take notes. This time i wont make that mistake, i already filled a whole notebook with this. Thanks Kilian, sad there isnt anything more tho
JULIA
Super cool! Thanks!
best lecture on naive bayes.
in lecture notes there is a spelling error in the concluding summary "week classifier"
lectures so good, kilian on my poster wall. :)
Are the slides for the first part of the class available?
I have been watching your lectures for years now. I must say, the style of teaching is the best ! Every-time I need a refresher on some topic, your ML series is the first I think of. Thank you for the amazing content! 😃
wonderful lecture
A Great Beginning..excited for the next
I always tried to help, each time i did the cult took advantage now its their problem, and i dont know if i can help anybody everything has changed since last night
Raise your hand if that makes sense… crickets… ok moving on!
dead mouse got me
Prof, record small videos on SVM, SVR and Soft margin SVM, if possible.
Pure gold. The lectures are excellent. The humor is spot on. Many many thanks.
wow, you are a good teacher!
Legendary course!
I'm curious if someone was actually stealing all the notes
geez does anyone ever wonder what beast of a middle school Killian went to? 37:29
End score tallly: Under-grad = 255 Grad = 310 Grad Won!!
