The Gothenburg group has developed a psychological model of patterns as seen and selected by humans, and incorporated it in their IQ test solving programs. The result is a program that attacks abstract problems using approaches similar to those a very smart person would use.

"Our programs are beating the conventional math programs because we are combining mathematics and psychology. Our method can potentially be used to identify patterns in any data with a psychological component, such as financial data. But it is not as good at finding patterns in more science-type data, such as weather data, since then the human psyche is not involved," says Strannegård.

The Cognitive Foundry is a modular Java software library for the research and development of cognitive systems. It contains many reusable components for machine learning, statistics, and cognitive modeling. It is primarily designed to be easy to plug into applications to provide adaptive behaviors.

The Cognitive Foundry's development is led by Sandia National Laboratories and is released under the open source BSD License.

scikits.learn is a Python module integrating classic machine learning algorithms in the tightly-knit world of scientific Python packages (numpy, scipy, matplotlib). It aims to provide simple and efficient solutions to learning problems that are accessible to everybody and reusable in various contexts: machine-learning as a versatile tool for science and engineering.

This article shows you how to write a relatively simple script to extract text paragraphs from large chunks of HTML code, without knowing its structure or the tags used. It works on news articles and blogs pages with worthwhile text content, among others…

imgSeek is a collection of free open source visual similarity projects. The query (image you are looking for) can be expressed either as a rough sketch painted by the user or as another image you supply (or an image in your collection). The searching algorithm makes use of multiresolution wavelet decomposition of the query and database images.

Two recent studies show that roboticists are applying some fresh thinking to the building and operation of robot hands, and a third suggests why the work is so important – it could be vital for domestic robots learning how to be useful around the home.

Open source Python modules, linguistic data and documentation for research and development in natural language processing and text analytics, with distributions for Windows, Mac OSX and Linux.

Pyevolve was developed to be a complete genetic algorithm framework written in pure python.

Many fast-growing parts of the Web, such as Facebook or Google's Picasa, are populated with user-generated images. They could become a rich advertising opportunity with the right technology, says Yang. "Many photos in online photo albums and video scenes do not have texts to describe them," he says. "People browsing through their own or others' online photo albums are a potential audience for adverts." Today, he says, it's impossible to reach people where there is no surrounding text.

To match an advertisement to an image, the group's software first converts the image to a collection of words. The software was trained to do this by crawling around 60,000 images on Flickr that have tags added by users.

A consortium of 11 railway companies launched the one-year pilot project last month, and has set up 27 of the high-tech advertising displays in subway commuter stations around Tokyo.

"The camera can distinguish a person's sex and approximate age, even if the person only walks by in front of the display, at least if he or she looks at the screen for a second," said a spokesman for the project.

If data for different locations is analysed, companies can provide interactive advertisements "which meet the interest of people who use the station at a certain time," the project said in a statement.
