I have taken the survey.

One mistake is treating 95% as the chance of the study indicating two-tailed coins, given that they were two-tailed coins. More likely it was meant as the chance of the study not indicating two-tailed coins, given that they were not two-tailed coins.

Try this:

You want to test if a coin is biased ...(read more)

If we're aggregating cooperation rather than aggregating values, we certainly can create a system that distinguishes between societies that apply an extreme level of noncooperation (i.e. killing) to larger groups of people than other societies, and that uses our own definition of noncooperation rath...(read more)

> Back up your data, people. It's so easy (if you've got a Mac, anyway).

Thanks for the encouragement. I decided to do this after reading this and other comments here, and yes it was easy. I used a portable hard drive many times larger than the Mac's internal drive, dedicated just to this, and was ...(read more)

In part of the interview LeCun is talking about predicting the actions of Facebook users, e.g. "Being able to predict what a user is going to do next is a key feature"

But not predicting everything they do and exactly what they'll type.

I believe that was part of the mistake, answering whether or not the numbers were prime, when the original question, last repeated several minutes earlier, was whether or not to accept a deal.

I expect part of it's based on status of course, but part of it could be that it would be much harder for a mugger to escape on a plane. No crowd of people standing up to blend into, and no easy exits.

Also on some trains you have seats facing each other, so people get used to deliberately avoiding...(read more)
