I don't think that is correct. The numbers on the leaderboard are not the scores on the training set. The netflix prize uses three datasets: the training set, the leaderboard set, and the test set. The training set is distributed to e

I believe it is a consequence of A) netflix evaluating the algorithms in terms of the squared error and B) different classification algorithms making different types of mistakes. Take a simple example, with two movies (A and B), and two a

I believe that (expensive, politically problematic) high voltage DC lines can transmit electricity across the US (or europe, or china) with minimal losses. The more serious problem may be that the sun doesn't shine 24 hours a day. Though t

If I understand you, you are basically saying that the main effect of HFT is that the people who bought Broadcom paid more to the people who sold Broadcom, with a small percentage going to the HFT middlemen? Thus, HFT decreases the advanta

Why did you not provide a link to the Wikipedia page? http://en.wikipedia.org/wiki/Vinland_map#Authenticity_contro... I see nothing "proving" that it is a forgery. In fact, the wikipedia page presents an unclear picture, very similar to

Is there a reason you linked to the 3rd edition? Oddly, James Watson is no longer listed as an author in the 4th edition, and a bunch of other people are added.

Very interesting. Perhaps the article should be titled "boy discovers conditions under which bacteria eat plastic". It still seems like introducing the new bacteria into the environment would be pointless, though. If the conditions in th

Someone correct me if I am wrong here, but wouldn't this same selective breeding process happen naturally in any waste area enriched with plastics? (Bacteria will reproduce to the extent that they can metabolize the plastic.) The fact tha

I would be interested to know how you secured your monitors to the drafting table. Do you adjust the tilt, or only move the table up/down?

I think you are wrong to criticize him for submitting his own post. This is the only thing he has submitted, so it isn't like he is spamming the new page. It would be trivial to make a sockpuppet before submitting, so I think we should ap

The writeup doesn't emphasize that they actually had to do some rough 3d reconstruction to allow you to move to the buildings like that. This was a mixture of lazer and stereo vision.

The only country above the US that isn't an oil exporter is Luxembourg, which has a population about %0.1 of the US-- its basically a single, medium/small city. I bet if Beverly Hills became its own country, the per capita GDP would also b

You don't really need much math to understand this. Imagine that a person is a perfect cube. The amount of rain hitting the top of this cube is constant-- does not depend on the speed of the cube. The amount of rain hitting the front

It seems to me that the marginal cost for an ebook is indeed zero. (Or very, very nearly zero: do you count the cost of the electricity or bandwidth to download it?) You disagree?

Netflix has said that they are more interested in retaining customers than acquiring new ones. People sign up, watch the stuff they can think of, then quit. If they reliably use the recommendation algorithm, they will stay profitable mu

If ebooks cost 10% of what books used to cost, but everyone buys 10x as many books because of the lower cost, convenience of buying and storing them, etc., then the costs can be covered the same as today.

Not being affiliated with a PhD program isn't a problem in itself. Review is often double blind, and frankly I don't think most people care much about your credentials. However, it is very difficult to publish in many areas with out "spea

The cost of education isn't much of an issue. PhD programs in the sciences almost always cover tuition and provide a stipend in exchange for teaching or research work.

Interesting. I know that there is lots of activity in certain sectors of PC gaming based on a subscription model where piracy is also basically impossible. (World of Warcraft, for example). http://www.msnbc.msn.com/id/23800152/

Isn't the major point of this that it makes piracy impossible? I think that if there is no benefit (or even a small detriment) to the game experience, industry will still embrace this. As I understand it, piracy is essentially the reason P

It is a risk management thing. What is the probability that humanity figures out a way to cheaply and safely generate enough energy that we can afford to pull global warming gasses out of the air and stop burning fossil fuels? It seems to

Unless I am mistaken the valuation offer varies, so you really don't know how much of your company you will have to give away.

You might hurt yourself if one is much more profitable than the other. e.g. if you could charge $20 for the app, but no one pays that if a free (much less profitable) ad supported version exists.

Exactly right. Apple probably thinks that losing out on some sales in the worst market with huge discounts isn't worth destroying that brand. When things recover, and people expect PC notebooks to cost $500 and macs to cost $1500, that mi

Interestingly, the "assessed" value in Michigan appears to be 50% of the "fair market value" of the house. So that would be an effective tax rate of 2.25%, not 5.5%. (This still seems to be higher than other midwestern areas.) http://www
