Big Data Analysis of Sounds Creates 50-year Evolutionary History of Music Charts

May 14, 2015 9:18 am | by Queen Mary University of London | News | Comments

Evolutionary biologists and computer scientists have come together study the evolution of pop music. Their analysis of 17,000 songs from the US Billboard Hot 100 charts, 1960 to 2010, is the most substantial scientific study of the history of popular music to date. They studied trends in style, the diversity of the charts, and the timing of musical revolutions.

Predicting Human Crowds with Statistical Physics

March 3, 2015 10:36 am | by American Physical Society | News | Comments

For the first time, researchers have directly measured a general law of how pedestrians interact in a crowd. This law can be used to create realistic crowds in virtual reality games and to make public spaces safer. People intuitively know how to navigate through crowds in a way that both minimizes distance traveled and avoids collisions. But the 'force' that governs human interactions has been previously unknown.

Researchers have developed a statistical technique that sorts out when changes to words’ pronunciations most likely occurred in the evolutionary history of related languages. Their model gives researchers a renewed opportunity to trace words and languages back to their earliest common ancestor or ancestors — potentially thousands of years further into prehistory than previous techniques.

Explorations of Mathematical Models in Biology with Maple

February 10, 2015 9:29 am | by John A. Wass, Ph.D. | Articles | Comments

The author of this wonderful text delivers a brief, easy-to-absorb, yet very comprehensive text on modeling real-world data with Maple. Maple is software for performing mathematics, with a none-too-steep learning curve. In the introduction, the author is quick to point out that this is neither a detailed textbook of mathematical modeling, nor Maple. It is, however, a very well-written manual of introductory modeling and use of Maple.

Statistical decision making resembles a process Alan Turning's team did in Bletchley Park to work out the settings of German enigma machines. In order to make use of the large clicking machine, Turing's team analyzed pairs of randomly intercepted German messages, aligned them one above the other to accumulate evidence from letter pairs until they reach a threshold level of certainty that the messages were sent on identical enigma machine.

Cancer researchers must use one of the world's fastest computers to detect which versions of genes are only found in cancer cells. Every form of cancer, even every tumor, has its own distinct variants. A research group is working to identify the genes that cause bowel and prostate cancer, which are both common diseases. There are 4,000 new cases of bowel cancer in Norway every year. Only six out of 10 patients survive the first five years.

The Bulletin of the Atomic Scientists says Earth is now closer to human-caused doomsday than it has been in more than 30 years because of global warming and nuclear weaponry. But other experts say that's way too gloomy. The advocacy group, founded by the creators of the atomic bomb, moved their famed "Doomsday Clock" ahead two minutes on January 22, 2015. It said the world is now three minutes from a catastrophic midnight.

Optimization algorithms, which try to find the minimum values of mathematical functions, are everywhere in engineering. Among other things, they’re used to evaluate design tradeoffs, to assess control systems, and to find patterns in data. One way to solve a difficult optimization problem is to first reduce it to a related but much simpler problem, then gradually add complexity back in ...

The Power of Regular Expressions

A.J. Jacobs wrote: “I think there's something to the idea that the divine dwells more easily in text than in images.” Since there has been an explosion in the amount of text, sacred and secular, available to anyone with an Internet connection, the need for processing tools has grown. Regular expressions can be used to extract specific text from documents due to their ability to replace many lines of code with as little as one line.

Book Review: Applied Bayesian Modelling, 2nd Edition

This is not a text for the novice. However, for those math/statistics aficionados, there is much to be had. The book’s great strength lies in two areas: the first is Peter Congdon’s generation of an excellent bibliography of the most modern techniques available, and the other is his (slightly) more straightforward explanations of the strengths and weaknesses of these techniques and suggestions for optimizing the results.
