For me at least, sparse vector support means you can do elementwise operations (on the non-sparse elements) and in particular linear algebra like vector dot-products and matrix-vec…

You may want to check out the Yahoo cloud serving benchmark, it is a pretty standard load-testing tool for this kind of thing. https://github.com/brianfrankcooper/YCSB/wiki

I have been thinking for a while now about the applications of bandits to financial markets (not so much the Q- and TD- learning approaches as I am a bit less familiar with them). …

+1 for Langford. He and many others (e.g. Deepak Agarwal) at Y! are among the most prolific publishers on this topic. Check out: http://hunch.net/~exploration_learning/ for a good,…

Also worth looking at for linear SVMs: Sofia-ml which is a very fast linear svm and classification C++ package. Supports PEGASOS as well as logistic regression and also learning ra…

Congratulations! I was wondering why Bradford's posts were suddenly becoming so focused on the news and personalisation! :)

I'm curious as to what libraries are available for linear algebra and numerical computation (free / open source ones) and how they compare to e.g. Numpy, mpj or colt on java, etc?

I wonder what results a study into the differences in brain function (eg fMRI scans etc) between recalling normal memories and "fake" memories, perhaps using machine learning, migh…

Live in Rojan Club, Shanghai, China... And Liverpool University, those are all time faves!

I think Mark Shuttleworth's Thawte (bought by Verisign) is the only real example of a startup in the sense most on HN would think about it, at least at scale. It's also worth notin…

The fact that Dubai salaries are tax-free has a big impact too (although cost of living is quite high too (not relative to big US or UK cities but pretty high)). Also depending on …

Hopefully! It is great to work with some real world customer click data... If anyone is interested in a technical intro to the setting there is a set of slides from John Langford a…

Masters project on using bandit algorithms for optimising CTRs on website content. Also involves some search engine / text mining / dimensionality reduction stuff. A little bit of …

Only very few people have commented that, you are only 25! (I guess given the nature of the HN community :) I don't think anyone can consider themselves a failure at 25, having spe…

I wonder what exactly a "human-based" algorithm is? How do you not use stats, NLP, ML and/or network based approaches at that scale?

Agree with your points 1 and 2, for point 1 some sources are available e.g. http://the.echonest.com/

What's interesting about this is the mention of how they built a new and improved software system for the cash management. Wouldnt be surprising to see this pop up as a future clou…

Any chance of something like this in London?!

I am interested in this, but is it worth going if not a developer/designer but a (soon to be) machine learning masters graduate? ie does one get anything really out of it if you ca…

This article is at best inconsistent, at worst self-serving. Funny that Cuban wasn't complaining about traders when they were driving up tech stocks in the dot-com bubble that even…

Had a bedbug attack on some recent travels (stayed in dodgy hostels all over the world for 6 months and it happened in a nice hotel in Italy). We had our bags cryogenically frozen …

This is very similar to an idea I have had in my head for a while now (I put it up on the recent startup ideas Google spreadsheet). The main angle that I thought would be to have i…

http://portal.acm.org/citation.cfm?id=1582716.1582723 only paper I found. It's only a page though!

Mendeley may not be exactly what you have in mind, but perhaps starting to take some steps in the direction of more collaboration / social approach to research (including a persona…
