## Nobel prizes and facebook usage

Whether this is a joke or not (I was seriously contemplating writing a letter to the editor describing its stupidity), it serves as an awesome example of poor judgement, statistical misuse, and confounds. I have given it to my multivariate statistics students to practice writing critical annotations. In the meantime, I thought about another predictor for Nobel prizes. Since the number of Nobel prizes won by residents of a country has nothing to do with national chocolate consumption, it should have a strong relationship to the resources made available by a country to furthering science in every direction. Countries with such priorities typically have residents with more disposable income than countries that do not. And thus we find more money is spent on indulgences like chocolate.

I replicated the experiment, and confirm that the correlation between Nobel prize per capita and chocolate consumption per capita is strongly correlated, with a correlation coefficient of 0.625. I fit the best quadratic to the data as well, from which we see a diminishing utility of chocolate dosage to Nobel prize winning.

But what about something more ridiculous? So I looked at how the per capita Nobel prizes of a country is correlated with the percentage of a country on facebook. And indeed it is! With a correlation coefficient of 0.564. But more remarkably, the Nobel prize winning capacity of a country exponentially increases with the percentage of the country on facebook. Note that 0.946 is the starting per capita Nobel prize winning of a country without facebook, just because at least one person occupies that country.

So, today I am going to encourage my students to peruse facebook during the rest of my lectures because we have proven statistically the power of facebook for their scientific development. Our prizes await.

## My music in interesting contexts

A while ago, I gave free license to a film maker to use some of my music for her project titled "48 Hour Games." Now I am finding little teasers of the end result. I am quite pleased with what I see!

Here is a study.

## Po'D: A Survey of Evaluation in Music Genre Recognition

Hello, and welcome to the Paper of the Day (Po'D): A Survey of Evaluation in Music Genre Recognition. Today's paper is B. L. Sturm, "A Survey of Evaluation in Music Genre Recognition", Proc. Adaptive Multimedia Retrieval, Copenhagen, Denmark, Oct. 2012.

This paper is best summarized by a particularly riveting line of section 2.2:

The most-used publicly available dataset in music genre recognition work is that produced in [378,379], often called "GTZAN." This audio dataset appears in more than 23% (96) of the references [5,11,14,16,18,27,33,35-40,53,57,58, 84,91,106,107, 109, 114, 130, 131, 136, 138, 142, 143, 163, 164, 177, 182, 191, 199, 201, 202, 204-206, 208, 209, 212-215, 217, 218, 223, 236, 237, 240, 241, 246, 270, 272, 285-290, 314, 318, 319, 322, 323, 325, 331, 336, 337, 339-341, 344, 345, 362-366, 368, 371-374, 377-379, 398,399,402,404,405, 407,411,416].
The numbers just sort of roll off the tongue. I think I might approach the presentation of this paper like at a humanities conference, where I read it. Aloud. With no slides. It is really only 7 pages of text, and 14 pages of references. I can skip the references.

And in the style of Harvard author name and date referencing, here is the first line of my paper:
