Bay Area Vision Meeting: Unsupervised Feature Learning and Deep Learning

[leverwang]

Yes, unsupervised learning! We have taught too much on classification, regression, SVM, ANN, that focus on supervised learning. Our brains are sub/un-consciously learning about the environment continuously, i.e. doing unsupervised learning.

Mr Ng has an interesting pattern in his own speech... starting a sentence in a clear strong audio, and fading to a silent muted tone at the end of a sentence. :) (makes it difficult to hear the complete statement sometimes )

Andrew Ng is the best professor I've ever had the privilege to learn from (ml class). 

[Funtasmia]

guys dont forget his free online Machine Learning class starting in January.

[ahmedgalcaio]

andrew a great machine learning scienctist

[adelle0001]

napakaganda ng video! another one from google

[artificialintellige1]

REALLY VERY GOOD VIDEO

[mehdigoudarzi]

amazing!

Usually by an iterative process that first finds a set of basis vectors that sparse represent the current set of observations (images), and then finds new sparse representations (the alphas) using that set of basis functions. Rise and repeat.

[matpalmyt]

i don't get how the phi basis functions at 13:00 are derived?

@matpalmyt neither do I D:

[cijojose1]

Awesome lecture

[wblnumber1]

Fantastic lecture!

[lei07fun]

This talk is awesome; I can quickly pick up key points of deep-learning.

[Mangalaiii]

Andrew Ng got bored of improving one algorithm so he decided to improve all algorithms at once...

[beardymonger]

i envy people living in the bay area.

Redmond (just kidding)

[malusmoriendumest]

Intriguing ideas.

[SalsaTiger83]

If you are interested in Machine learning, see Stanford's Machine Learning Course, here on youtube by the same speaker Andrew Ng

[paucarre]

Excellent video, very informative and didactic
