After 60 years of false starts, the integration of artificial intelligence with probability and statistics has led to a marriage of machine learning, control theory and neuroscience that is yielding practical benefits. This shared theoretical foundation, combined with the exponential growth of processing power and the unprecedented increase in the amount of data available to analyze, has made AI systems attractive for businesses to adopt.
Research using cutting edge computer analysis reveals that despite mutating, Ebola hasn’t evolved to become deadlier since the first outbreak 40 years ago.
As part of the 2015 Cambridge Science Festival, David Spiegelhalter, Winton Professor for the Understanding of of Risk at Cambridge University, has given an overview of the history of sex research using data going back to 1580, conducted by pioneering sexologists through to today’s ‘sexperts.’
This delightful and informative guide from my friends at No Starch Press comes with the following cover blurb: “Statistics Done Wrong is a pithy, essential guide to statistical blunders in modern Science that will show you how to keep your research blunder-free.” It is somewhat pithy, but as to blunder free, I will quote the old maxim that “nothing is foolproof, as fools are so very clever.” Still, the book has much to recommend it.

Cicero said: “The shifts of fortune test the reliability of friends.” Fortunately, the reliability of processes can be more easily understood than friends. It is defined as the probability of performing a specific function under certain conditions for a specific period of time without failure
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.
To bring facts and clarity to the public debate about immunization in light of the recent measles outbreak, the University of Pittsburgh Graduate School of Public Health unveiled a computer simulation that explores the impact of measles outbreaks in cities across the U.S. Users can see how an outbreak would play out if their city had high or low vaccination rates.
Researchers have developed a new, automated method for classifying hundreds of kilometers of the deep sea floor, in a way that is more cost efficient, quicker and more objective than previously possible, estimating geographic distribution of life on the sea floor using a combination of submarine mapping technology, statistics and a landscape ecology technique called Niche Theory.

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.
Eve, an artificially-intelligent ‘robot scientist’ could make drug discovery faster and much cheaper, say researchers. The team has demonstrated the success of the approach, as Eve discovered that a compound shown to have anti-cancer properties might also be used in the fight against malaria.
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 five universities have been selected to lead the new Alan Turing Institute. The Institute will build on the UK's existing academic strengths and help position the country as a world leader in the analysis and application of big data and algorithm research. Its headquarters will be based at the British Library at the center of London’s Knowledge Quarter.
Scientists using supercomputers found genes sensitive to cold and drought in a plant help it survive climate change. The computational challenges were daunting, involving thousands of individual strains of the plant with hundreds of thousands of markers across the genome and testing for a dozen environmental variables. Their findings increase basic understanding of plant adaptation and can be applied to improve crops.
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 ...

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.
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.
