These programs work pretty well: Children using an autotutor for math progress much faster than those who get just a regular textbook or are stuck in a crowded classroom with no one-on-one instruction.

There’s one snag, though: Autotutors can’t tell when a student is bored or frustrated. A regular teacher can spot this instantly and intervene. So Woolf decided to tackle the problem by designing a computer that senses emotion.

Drools Guvnor – JBoss Community

Brent Sordyl — Thu, 25 Feb 2010 15:00:02 +0000

Drools Guvnor is a centralised repository for Drools Knowledge Bases, with rich web based GUIs, editors, and tools to aid in the management of large numbers of rules. As you know, Drools allows you to create executable knowledge bases. The repository component is where you can store versions of rules, models, functions, processes etc that all relate to these knowledge bases. Access is controlled, and it is possible to lock down access and restrict features so domain experts (non programmers) can view and edit rules without being exposed to all the features at once.

You would want to use Guvnor if

* You have a need to control access to rules and other artifacts
* Have a variety of non programmer users who could use graphical editors to edit rules
* Need to manage versions and changes to the rules over time (and you probably have a lot of rules !).

Bayesian Classification on Rails | Logan Koester

As anyone who uses Twitter can attest, even with some very specific search terms, language filtering and geocoding, there is going to be a lot of white noise. I decided to take this one step further.

Bayesian classification (your garden-variety spam filter) in ruby is quite easy, thanks to ruby-stemmer and the excellent classifier gem. The canonical example:

Eureqa – software tool for detecting equations and hidden mathematical relationships in your data

Brent Sordyl — Sat, 05 Dec 2009 17:00:04 +0000

Eureqa is a software tool for detecting equations and hidden mathematical relationships in your data. Its primary goal is to identify the simplest mathematical formulas which could describe the underlying mechanisms that produced the data. Eureqa is free to download and use. Below you will find the program download, video tutorial, user forum, and other and reference materials.

The Future of Artificial Intelligence – NYTimes.com

Today, artificial intelligence, once the preserve of science fiction writers and eccentric computer prodigies, is back in fashion and getting serious attention from NASA and from Silicon Valley companies like Google as well as a new round of start-ups that are designing everything from next-generation search engines to machines that listen or that are capable of walking around in the world. A.I.’s new respectability is turning the spotlight back on the question of where the technology might be heading and, more ominously, perhaps, whether computer intelligence will surpass our own, and how quickly.
