Herself’s Artificial Intelligence

I hadn’t heard anything about wavlets in several years and then this news story caught my eye.

. . .Meningiomas are tumours of the brain and nervous system and they account for 20% of all brain tumours. Doctors have a major problem of discriminating between the four different subtypes of meningiomas but doctors face three key problems in making such a diagnois:

– The work can be painstakingly slow requiring up to two hours of analysis and expert consideration of a full “slide” of information.

– The finest tumour specialists (histopathologists) can at times come up with completely contradictory findings based on slight variations in their method of analysis.

– Currently the slides that specialists examine contain a few million pixels of data and the task of tumour diagnosis is painstakingly slow already. This problem is quite literally growing as medical equipment is coming on stream that can produce slides with hundreds of millions pixel resolution.

. . .

Now researchers in the University of Warwick’s Department of Computer Science have devised a method of using “wavelets” to provide an automated analysis of the varying texture of the tumours and guidance to doctor’s within seconds of being presented the data.

Path Intelligence has developed software to track pedestrians by analyzing their mobile phone signals. Monitoring units can be placed about a mall or store and the units fetch a unique signal from shoppers phones and track the shopper’s path.

Stores are provided with easy to use interfaces for the data, weather information, and SMS notification of trouble ( people in unauthorized areas or left packages ) to security personal.

Customers in shopping centres are having their every move tracked by a new type of surveillance that listens in on the whisperings of their mobile phones.

The technology can tell when people enter a shopping centre, what stores they visit, how long they remain there, and what route they take as they walked around.

The device cannot access personal details about a person’s identity or contacts, but privacy campaigners expressed concern about potential intrusion should the data fall into the wrong hands.

The surveillance mechanism works by monitoring the signals produced by mobile handsets and then locating the phone by triangulation – measuring the phone’s distance from three receivers.

While most of the artificial intelligent design of websites has come in the form of ‘Mechanical Turks’ better known as Web 2.0. Here is someone using an evolution algorithm to design a website.

Matthew Hockenberry and Ernesto Arroyo of Creative Synthesis, a non-profit organisation in Cambridge, Massachusetts, have created evolutionary software that alters colours, fonts and hyperlinks of pages in response to what seems to grab the attention of the people who click on the site. See Creative Synthesis for more. [ read more Web pages come alive and start breeding]

They defined the design of a webpage as a search problem. Then they broke html and css elements up into the smallest possible items. Those items are the dna, the webpage is the environment.

The best design attracts the most and longest attention. Here is the end result and some of the designs along the way AAAI.jpg
