Studies of vulnerable populations get a ‘bootstrapped’ boost from statisticians

A hallmark of good government is policies which lift up vulnerable or neglected populations. But crafting effective policy requires sound knowledge of vulnerable groups. And that is a daunting task since these populations—which include undocumented immigrants, homeless people or drug users—are usually hidden in the margins thanks to cultural taboos, …

Researchers develop new approach for better big data prediction

Researchers at Columbia University, Princeton and Harvard University have developed a new approach for analyzing big data that can drastically improve the ability to make accurate predictions about medicine, complex diseases, social science phenomena, and other issues.

Making teeming masses predictable

Once every three years, millions of Hindus gather for the Kumbh Mela, the biggest religious festival in the world. This spring, 60 to 80 million pilgrims travelled to the banks of the Shipra river, at the holy city of Ujjain, in central India. On the busiest days, as many as …

Can maths help you win at roulette?

Albert Einstein supposedly once said: “No one can win at roulette unless he steals money from the table while the croupier isn’t looking.” From:: Phys.org: Mathematics News

New algorithm provides better predictions of individual preferences

A collaborative of researchers has developed a filtering model with an associated scalable algorithm that makes accurate predictions of individuals’ preferences. The new approach is based on the explicit assumption that there are groups of individuals and of items, and that the preferences of an individual for an item are …

A good combination: Model and experiment for a deeper look

Doctors performing medical check-ups want a full picture of the patient’s health without using the scalpel. Engineers who want to investigate the stability of a bridge without cutting into it are in the same position. Non-destructive testing methods play a major role in guaranteeing quality and safety, driving substantial interest …

New math tools for new materials

University of Utah mathematician Graeme Milton presents a new tool for understanding how energy waves move through complex materials, opening up possibilities to design materials that absorb or bend energy as desired. His solution for so-called “analytic materials” was published November 15 in Proceedings of the Royal Society A. From:: …

The mathematics of coffee extraction: Searching for the ideal brew

Composed of over 1,800 chemical components, coffee is one of the most widely-consumed drinks in the world. The seeds (coffee beans) from the plant of the same name are roasted and ground, allowing a flow of hot water to extract their soluble content. Undissolved solids are filtered from the dissolved …

Mathematical algorithms calculate social behavior

For a long time, mathematical modelling of social systems and dynamics was considered in the realm of science fiction. But predicting, and at once influencing human behavior is well on its way to becoming reality. Scientists at the Technical University of Munich (TUM) are currently developing the appropriate tools. This …

Getting the most out of fractional models

Machines make our lives easier in many ways. Whether it’s a smart thermostat that learns when to turn the heat on or automatic brakes, machines traffic in the language of classical calculus. Classical calculus is good enough to capture the basic features of biological or mechanical systems and even human …
