Aside: how do you pronounce his surname?

He spent a couple of years in Singapore, so I'm going by the pronunciation there. (May be different in different regions, and I'm not sure about his preferred pronunciation now). It would do something like this: Start with the word "urn". Now don't drag it out, make it short. Make the "n" and "ng" sound at the end (urng). Now take out the "r" sound (uhng). It seems like Americans do tend to pronounce it "ehng" instea…

As a Singaporean, this is the correct answer.

I look at announcements like this, and past ones about Ng, and I always marvel at how things have gone since I took and completed his 2011 ML Class... That was one helluva course, challenging and interesting, and fun all at the same time (and so much "concretely" - lol). From what I understand, that course is still available thru Coursera (which Ng booted up after the ML Class experiment; Udacity was Thrun's contribu…

Nice. I wrote down my thoughts after taking his new DL course. Hope it helps you all :) https://medium.com/towards-data-science/thoughts-after-takin...

The final project in that course should be using ML to detect every time Ng says "concretely" and compile those clips into a video montage.

Its already done https://www.youtube.com/watch?v=5ZNJPSe1nZs

Thanks for the link to a few concrete examples! :-D

I took CS221 from Andrew in 2006 (or was it 2007?) Even more has changed since then ;-) It was my second ML course, after taking Daphne Koller's punishing CS229. Right then though I knew ML will sweep the world pretty soon.

i thought Daphne Koller taught CS228. probabilistic graphical models. It was very very grueling when i took it in 05.

Daphne has a PGM course on coursera as well. From the half dozen courses I have done on coursera that was by far the most difficult one, to the point where people were talking about making t-shirts stating "I survived week 5". Personally I found it the most interesting and rewarding as well.

I'm curious to the opinions of people here on companies collecting data to build data sets vs. privacy.

Indeed, it is very frightening what the companies can do with user's data. While in U.S, the data of a user may reside in the cloud of multiple companies and needs to be aggregated to be useful, in China, companies like Tencent knows about almost everything about every user: your IM messages, your purchases, the movies/music you like, the news you read, your geolocation. I cannot imagine what they are capable of with all those data. Think black mirror.

Thanks for this! You just reignited my interest in ML, months after dipping my toes at the end of EDx's Intro to Computational Thinking and Data Science.

How long did the courses take you to complete ?

Have you ever seen a child learn how to speak? He also needs loads of "labelled" data to initially learn about concepts.

The data is not labelled in the same way. The child has still acquired their knowledge solely from sensory experience. How do they know to apply the spoken label "mom" to the recurring pattern in their visual data stream? With modern data sets and labelling, so much of the problem domain is deeply hard-coded into the system. It doesn't have to learn what letters and words mean and how to identify them in a totally ar…

Unlabelled datasets are valuable in themselves.

Big companies have valuable datasets, small companies have talent. It makes sense for big companies to acquire talent, not datasets.

plus acquiring data is trivial compared to devising a good model

I think (hope) you missed a sarcasm tag there?

I spend 90% of my time manipulating data to try to build bigger, better datasets, and only 5% modelling.

It's far from challenging. The Stanford one (CS229) is though.

It's not a competition you know ;)

There are two versions of Ng's course, one is on Coursera, the other one taught at Stanford, both available online. Just wanted to point out that the Coursera one is much easier.
