I really liked this slideshow. My brain could almost learn to see his movements like this was a video.
good content. video lags constantly and becomes unconvenient for our eyes. please prevent such lags.
If you are having lag issues ... helper.ipam.ucla.edu/wowzavideo.aspx?vfn=10595.mp4&vfd=gss2012 This video from the site posted by David Sanders (see below) was working better for me.

VertigoAt1977 Your'e welcome. If you like a video like this, you are my kind of people. -Happy to help.
Many thanks for sharing the lecture, it's so clear and concise. Now, I've an overall better understanding of the difference between various machine learning algorithms.
This is all about applications of deep learning, and give an intuitive explanation of why deep learning works well. G. Hinton and Y. Bengio released several presentations online that present detailed and theoretical part of deep learning. I started my study from there.
I remember working on Natural Language Processing as an undergrad in the 80's ... it's come so far ... of course, back then we didn't compete with Neuro-Linguistic Programming for the NLP acronym.
This was the video i am looking for after machine learning classes of him. I hope we'll meet in some conference.
I'm in the field since 2010 machine learning and computer vision.. man this is a great state of the art presentation.. Nice ... really nice
Man Dr. Ng is such a humble man.
I like Andrew Ng. He is always so humble!
Thank you very much for sharing this! That gave mere new direction to extend my knowledge
Great video, but intermittently very choppy for some reason.
I feel the same way currently - is that machine learning tends to be just curve fitting and statistics. This is not what I really want to learn when I say I want to learn AI/Machine Learning.

So up to you to invest your spare time into finding new methods, right? I think having a stereoscopic view or a time element, or both will greatly help improve image recognition algorithms. I think humans would also have a lot of trouble recognizing motorcycles if they spend their entire lives living in a world of non-moving 2D images. The reason we can pick apart objects from others is because we have seen them often, at other times, as if moving in 3D space. Humans use a combination of parallax and both eyes to map their 2D view into a 3D understanding of the world. If we want computers to make sense of the world in the same way as we do, the first preprocessing step would be to do the same: try to guess a 3th dimension onto 2D images. Just my thoughts. Might be utter bullshit :)
In case anyone is curious, the powerpoint presentation Andrew is giving can be found just by Google searching "DeepLearning-Mar2013.pptx". If you want to see some of the slides that Andrew talks to but which do not get into the video, this is helpful.
Great video! Thank you! I can listen to Andrew Ng all day...where is part 2?
I would love to study side by side wth this guy!!!!!! He rules!!!!

Wow - great talk! Extremely interesting material. I've been fascinated with AI every since I was a kid. In fact, I think that's what got me into the field of software dev in the first place. Mayhap it's time to truly start playing around with neural nets and learning algorithms.

It doesn't actually inspire too much confidence that some of the greatest brains on the planet developing AI that will presumably be responsible for our safety and well being can't figure out how to upload a decent quality KZread video ten years after its inception. ;D (jk btw)

The thought had crossed my mind, but I decided to keep that to myself.
Should all AI have a standard eventually for a "base" brain? Should an individual AI be on a knowledge island of their own or should they all be interconnected and all be able to share their acquired learning and knowledge?
We're a start up called "#Winning" and we're using convolutional neural networks to predict lottery numbers. We're currently training a recurrent network on coin tosses and dice rolls before moving onto the holy grail (but never holy fail) of predicting next week's lottery numbers
I wish Andrew would move forward from text, audio and images/video as there are more interesting problems and I'd like to hear about possible solutions to these problems via algorithms.
Well, Gabor-like filters that deep nets tend to discover are the basis of JPEG which is an important part of MPEG compression. But it's only one layer of "features" and there are no learned temporal features that take advantage of the redundancy from frame to frame. The keyframing technique does not count as a learned feature. Geoff Hinton has applied stacked restricted boltzmann machines to video of bouncing balls and found that it can learn temporal features, so yes!
Amazing video!
Need an unsupervised learning algorithm to fill in the gaps of the video lag. Other than that, really good!

Found this in a probabilistic programming playlist. When does that portion of the talk start?
at 24:00 the edges numbers 36 and 42 are misrepresented :)
He is using the same table of numbers to represent an image on several different talks.
Great video !
In-lecture quizzes: tested on Coursera, now applied to in-class lectures.
thks for uploading this video
thx for the upload!
just appreciate the video guys.
Help!! I am currently working on spatio-temporal feature extraction from videos using deep learning. Unfortunately there hasn't been much work on it. Can anyone provide me with links on deep neural networks for video features???
great!
parse the data into feature vectors very interesting idea=)
clear and rich
The statement at 19:30 "Humans have 20 years of experience looking at unlabeled images" is nonsense. Human experiences are always labelled by their feelings (aka rewards in machine learning).
Can you apply these types of techniques to video compression?

The early pre-cursor to the tongue "display" (which apparently feels like varying degrees of soda bubbles rather than a 9V battery) was actually a giant chair that replaced pixels with little actuators. Turns out skin isn't so good with definition whereas the tongue is super dense with sensors - more "pixels per inch" if you will.
Is there a reason to stop at only 4 levels of hierarchy for feature learning? Why not 16 or 32 or 256?
Did I hear correctly, single learning algorithm is Andrew Ng's hypothesis? Like, his invention?

Oh my god this is great
how can you have so much knowledge and talk about deep learning and advanced AI but not be able to record a 45 minute video? i really don't understand that...
SimpLe, yet informative :)
Nice
It's great
yeah, found you.

I want andrew G to come up with an algorithm that just says, this video has has been recorded in a crap way..
Can you guide me to learn deep learning pls
The choppiness is in the video. Biology, layers: 20:15 - 33:41
11:00 still i wonder why our brains are so similiar and these brain regions are normally structured according to one specific task, optical cortex for seeing things, and auditory cortex for understanding sound frequency modulations. Why do certain sensory task occur in the same brain regions. That is my question, thanks for the replies if there are any;D really intresting stuff AI!!!!!! 2040 the internet will be alive!;p

+Vrolijke Vent Long wires are expensive. Total connectivity in the human brain is about 15%. It's nonsense to connect A1 with V1. The genes know that and therefore brain region connections are predefined in order to speed up learning.
Impressive...the sparse coding of him, in this video.

Certainly, considering the brain does it.
I think the real question here, is HOW the FUCK is his last name pronounced???

Voxel Skull it's a chinese surname used by certain dialects, en.wikipedia.org/wiki/Ng_%28surname%29 similar (in chinese character) to those with 'Huang' as surname. You can pronounce it like "earn" but with a 'g' at the end... so well, "earng".

Did he seriously have to defend himself for being inspired by nature? deliberately avoiding the term "evolution"??? at around 8:45 min
