Heroes of Deep Learning: Andrew Ng interviews Geoffrey Hinton

[@aliasad8342]

Hinton's Advice: #1 - Read the literature but don't read too much of it. #2 - For creative researchers, I think what you want to do is to read a little bit of the literature and notice something that you think everybody is doing wrong and contrarian in that sense, you look at it and it just doesn't feel right and then figure out how to do it right, and when people tell you that's no good....just keep at it. And I have a very good principle for helping people keep at it. Which is, either your intuitions are good or they're not. If your intuitions are good, you should follow them and you will eventually be successful. If your intuitions are not good, it doesn't matter what you do. #3 - Never stop programming! #4 - I think one should reach enough to start building intuitions and then trust your intuitions and go for it. And, don't be too worried if everybody else says is nonsense. #5 - If you think its a really good idea and other people tell you it's complete nonsense, then you know you're really on to something. #6 - one good piece of advice for new grad students, see if you can find an adviser who has beliefs similar to yours because if you work on stuff that your adviser feels deeply about you'll get a lot of good advice and time from your adviser.

29:59 this is where Hinton actually says that

[@wk4240]

Good principals to follow. Regardless of what you are doing.

[@dbiswas]

I attended one of his lecture in Washington University,. He is extremely humble and a great speaker. He is the Einstein of our generation. I am really looking forward to his upcoming paper on Capsule theory. God ! it gives me a feeling like standing in queue for the latest iPhone. LOL !

Even Andrew looks super-exciting in the video, imagine the viewers. :)

[@saraths6184]

Two legends talking on a domain they help build. No surprise it turned out so informative. Thank u for making this video.

[@doryds]

Utterly fascinating. Professor Hinton is inspiring.

[@alexandeap]

Dear Andrew, first of all I wanted to thank you and the entire coursera team for the great academic contribution they give us. Secondly, I wanted to ask you to put the subtitles where possible so that we can enjoy 100% Spanish and South American speaking. finally ask you to include the course of neural networks of Jeoffrey Hinton since when you search through the search engine of coursera it does not find it. I will thank you for correcting this error because when I tried to search for the courses offered by the University of Toronto, I did not have a positive success either. Thanks again to you and the coursera team for the great innovative academic contribution and scientific and technological research.

[@reoext]

This is very interesting in terms of Prof. Hinton's historical perspective on his interest and development of many algorithms. Also, Prof Ng contribution to making everyone dreams become a reality from learning ML and applying in their prospective jobs. Thanks to both!!

[@MilanAndric]

Fav quote, little after minute 30... "Either your intuition is good or its not. If its good you should follow them and eventually you will be successful. If they are no good it doesn't matter what you do. There's no point in not trusting your intuitions."

Great interview, but it's so deep. I wish I could understand more of it...

[@Trackman2007]

"Finally Andrew Ng bought a decent mic!" - nah.. have to edit myself. At around 27:00 and on he returns to toilet/pillow-filtered sound. That's just Andrew Ngs trademark!

[@wajdanali1354]

honoured to listen to this discussion , subhanallah

[@yuwuxiong1165]

Excellent interview...and very good advises from Hinton!

[@briancase9527]

I so agree with Hinton: have an idea and go for it. I took this approach with something other than AI, but it also worked. What do I mean? I mean, even though my idea wasn't revolutionary and totally worthwhile, I LEARNED A LOT by just going for it and programming the heck out of it. The practical experience I gained served me well--very well--in my first jobs. Remember: your purpose is to learn, and you can do that following your intuition--which is fun--or following someone else's--which is less fun.

[@morebaie3412]

This interview is highly insightful and helpful for deep learners, recommended watching!

"When you have something you think is a good idea and other people think it's a complete nonsense, then you know you are onto something"

[@bobcrunch]

Three years ago I took Ng's Machine Learning Coursera class and it really got me hooked on the subject. Then in the spring of 2017 I took Hinton's Neural Networks for Machine Learning Coursera class and it was a big step in my understanding the subject. Hinton's class goes 15 weeks and is a little intimidating in both depth and breadth. I have the math background so that really helped. I guess the bottom line is that if you're going to study the subject, study math through partial differential equations.

[@bobcrunch]

Most of the backpropagation is just add-subtract-multiply, but the tricky step is to calculate the updated weights using gradient descent.

[@woolfel]

Thanks for this excellent interview. I'm totally geeking out at this interview!

[@CHECK3R5]

38:00 onwards, brilliant philosophy of AI from this legend.

[@LuisGuillermoRestrepoRivas]

Interesting and informative. Thanks. But, on the last part: I believe that the symbolic approach of AI should not be totally abandoned by the researchers. One reason, by no means the only one, is that it gives AI a less of a "black box" approach than neural networks.

[@tommygunhunter]

symbolic.... total baloney! Symbols and indeed mathematics in general are emergent entities of the brain. AI if it is to replicate the workings of the brain has to dig deeper, be more subatomic, less molecular as therein lies the route to a multitasking, general intelligence.

[@brishtiteveja]

I love Andrew so much. :)

[@PaulHigginbothamSr]

I think the difference between wake and sleep is during sleep it is in the testing phase and during wake it is the operative phase of learning.

[@koendejonghe1555]

At 32:08 : Never stop programming!

[@brandomiranda6703]

that advice wasn't clear to me...is the advice to never stop programming cuz if a "bad student" doesn't make the idea work then if you don't lose your edge on programming then you can make work yourself?

[@falcon20243]

You only understand the tiny details when you can write a program to implement the whole thing yourself.

[@brishtiteveja]

And stop copy pasting and make mistakes and fix the bugs I guess !! :)

[@KangZhang]

Never stop programming !

[@brandomiranda6703]

Funny but important (?): “You either have good intuitions or don't. If you have good intuitions you’ll eventually be successful but if you have bad intuition no matter what you do it will suck, so follow your intuitions”-paraphrase of Hinton's research advice. What do people think?

[@brandomiranda6703]

Don't give up (but in a smart way) seems to be better advice and I agree. You know where he borrowed it from?

[@allenwang3331]

I think his intuition comes from his experience in diverse disciplines. He mentioned that he tried physics, physiology, psychology and philosophy during his undergrad. Intuition isn't some magical ability you're born with. It builds as you get exposed to information - similar to how variation in training data is beneficial to a good machine learning model.

[@daviddav2845]

if u live long enoguh bad become good. trouble is we have short life span... so if you suspect u have bad intuiation , look deeper into your heart to find a better one which yiu can use to explain everything happen to you and around the world. Then u should arrive on some decent intuition.

[@runvnc208]

Its also his clarity of writing I think. His papers are easier to understand for me than a lot of others.

[@MattRiddell]

Wow - the capsule concept is pretty close to the thousand brains idea!

[@Gabcikovo]

38:10 a thought is just a great big vector of neural activity

[@Gabcikovo]

38:19 people who thought that thoughts were symbolic expressions made a huge mistake.. what comes in is a string of words, and what comes out is a string of words, and because of that, strings of words are the obvious way to represent things, so they thought what must be in between was a string of words or something alike.. Hinton thinks there's nothing like a string of words in between, he thinks thinking of it as of some kind of language is as silly as the idea that understanding the layout of a spacial scene must be in pixels :))

[@KulvinderSingh-pm7cr]

Enlightened !!

[@godbennett]

Based on Hinton's descriptions of capsules, is it possible he has overlooked manifolds? It is pertinently the behaviour of manifolds, where solutions or sub manifolds (i.e. latent vectors on the states of particular concepts in the input space - some latent z is entailed by some factor distribution : {position, scale…}) are observed to lie in local patches of the global manifold, that engender that particular factors may be learned; for example pixels in the neighbourhood of some other pixels may signify transformations on that same pixel, while other neighbourhoods may be disentangled from the sampled latent vectors of the aforesaid pixel altogether, (i.e. other pixel data and their transformation data are separable from the events of the pixel discussed above)

[@AhmedKachkach]

Hinton surely did not overlook manifolds. The "routing by agreement" bit is where the main difference is; The way traditional CNNs learn means that they would not generalise as well as capsule nets; a lot of the information is lost / duplicated. Capsule nets (with this focus on "concepts") would be biased to learn more re-usable concepts, with different properties.

[@hiauoe]

Anybody know if anything was published about his stack of auto-encoders backprop idea? Would love to hear more about it

[@evankim4096]

WOW I can't believe Hinton et al came up with an algorithm for STDP decades before neuroscientists came up with the concept....He is talking about this algorithm that came in the late 1980s, while STDP arrived on the scene in the early-mid 2000s

[@AlinNemet]

YESSS! A technical tour-de-force! The Godfather! Gotta love the consistent elephant in the room though. AI inevitability: Human intelligence becomes obsolete for any purpose beyond the banal. Luckily, the onset of autonomous AGI (consciousness optional) solves this permanently. ;-[ Intelligence is THE differentiator on earth; let's relentlessly pursue / design Humanity's successor as Apex Predator. GAN indeed. GONE, more likely. Just keep kicking the can down the road, you clever hand-wringers. Learning leads to Knowledge, Knowledge is Power, Power corrupts, absolute Power corrupts absolutely. A clearly sub-optimal general (Human) outcome, driven by an optimising, self-adjusting, closed-loop feed-back system. Brilliantly myopic.
