Live Science Web Site

This is a nice popular science site with a lot of information regarding both natural and human sciences @ http://www.livescience.com/.

Be sure to check the Science Myths page ("we are using only 10% of our brain" and the like) @ http://www.livescience.com/bestimg/result.php?back=&cat=myths

Soar

Soar is a unified architecture for developing intelligent systems. That is, Soar provides the fixed computational structures in which knowledge can be encoded and used to produce action in pursuit of goals.

There are free Soar tools @ http://sitemaker.umich.edu/soar/soar_software_downloads

The FAQ is @ http://acs.ist.psu.edu/soar-faq/soar-faq.html

Revolutionizing Science & Engineering Through Cyberinfrastructure

This is a report on the topic of cyberinfrastructure needed for science & engineering published on January 2003.

Find it @ www.nsf.gov/cise/sci/reports/atkins.pdf

It is from the National Science Foundation (NSF) Blue-Ribbon Advisory Panel on Cyberinfrastructure and is also known as the Atkins report.

By the way, NSF sometimes is referred to as Never Sufficient Funds!

Free Machine Learning Software

Weka (Weka is an endangered flightless bird with an inquisitive nature) is a free Machine Learning Workbench from the Computer Science Department at the University of Waikato, NZ.




It is useful for mining underlying data patterns in large data sets but is far more than a glorified neural network system. It does a variety of regression, clustering and classification problems as well as many statistical analyses to assist in better discovering and understanding patterns in large (or smaller) data sets. It contains several familiar neural networks as well as others developed specifically for the program. To make it even more useful, there are extensive graphics capabilities so that one may visualize patterns and results to further suggest different lines of analysis.

It is Java based and the release and developer branches require Java 1.4 and 5.0 respectively.

Download it @ http://www.cs.waikato.ac.nz/~ml/weka/

There is also a very active users group that can be accessed on line @ list.scms.waikato.ac.nz/mailman/listinfo/wekalist

The developers usually refer users to the Witten and Frank text for questions (see below).

It was announced that Pentaho, an open source Business Intelligence organization, acquired the Weka project.

Placebo Effect

I am including here an excerpt from the Wall Street Journal, 03/01/2007, Page BI article titled "Emerging Drugs Show Promise Against HIV":


"Robin Isaacs, Merck's executive director of infectious-disease clinical development, said the two latest studies show the drug, taken twice a day, helped drive virus levels down to undetectable in slightly more than 60% of volunteers when added to an antiviral cocktail. Only 33% to 36% of patients receiving a placebo had similar reductions. Volunteers taking the new drug also saw higher levels of CD-4 cells than patients receiving placebo. A Merck spokesman said the company expects to file for FDA approval in the second quarter of this year."

I have highlighted the part that I find astonishing - that 33 to 36 percent of the patients on placebo had the same response as those on the actual drugs.

Yes, Virginia, there is a Placebo Effect.

Only if we knew how to harness it.

AI Add-ins for Excel

If you are like me and are interested in building solutions for clients who can benefit from AI technologies, it will be a good idea then to consider Excel. MS Excel is pervasive, people understand it, it is inexpensive, and it has tremendous analytical capabilities. And there are a lot of COTS solutions out there for it in the form of Add-ins. Examples are:

1. Neuranalyst @ www.cheshireeng.com/Neuralyst/nrlnfe.htm which is a general purpose neural network engine.

2. Data Intelligence Add-In @ http://www.aicomponents.com which is offering decision trees, clustering, association rules and feed-forward neural network algorithms

3. nn_Solve is a neural network model built with MS Excel. User will learn how easy it is to use a worksheet as a powerful forecasting tool @ http://www.xlpert.com/

4. NeuroXL Classifier is a neural network software tool for classifying data in Excel. There is also NeuroXL Predictor which is a neural network forecasting tool. Find them both @ http://www.neuroxl.com/

5. Braincel: Neural Net Add-In Module @ http://www.jurikres.com/catalog/ms_bcel.htm

6. Alyuda Forecaster XL @ http://www.alyuda.com/

7. NeuroSolutions @ http://www.nd.com/

8. Tiberius Data Mining has TiberiusXL @ http://www.philbrierley.com/main.html?code/vba.html&code/codeleft.html

9. ClassifierXL @ http://www.dotxls.com/excel-stock-market/80/classifierxl-data-mining-and-pattern-recognition

Do Animals Posess A Sense of Beauty?

It was Stendahl who defined "Beauty as the Promise of Happiness". And Robinson Jeffers who wrote:


"Or as mathematics, a human invention

That parallels but never touches reality, gives the astronomer

Metaphors through which he may comprehend

That powers and the flow of things: so the human sense

Of beauty is our metaphor of their excellence, their divine

nature:-like dust in a whirlwind, making

The wild wind visible."



So I far as I know there has not been a lot of studies on chimps, dogs, or song birds to determine if they possess, like man, a sense of beauty.

I have in mind experiments in which animals are exposed to human music, either voice or instrumental, and their reaction are measured in some manner. Or ones that make changes to the physical environment of the subjects - using color, size, and shapes as well.

(The research emphasis of neuroscience is always on cognition to the exclusion of other mental capacities.)



There are many studies that indicate that song birds have preferences for complex songs - if one considers that complexity is indicating "beauty". For example:


Catchpole, C. K., and Slater, P. L. B. (1995). Bird song: themes and variations (Cambridge University Press, New York).


And one that is comparing musical perception of humans and monkeys:


McDermott, J., and Hauser, M. D. (2004). "Are consonant intervals music to their ears? Spontaneous acoustic preferences in a nonhuman primate," Cognition 94, B11-B21.


So, I think the question that I posed still remains unanswered.

The Adventures of Action Item





Five Rules for the Evolution of Cooperation

This is an article by Martin Nowak on the rules needed for evolution to construct new levels of organization via cooperation among agents.

http://www.fas.harvard.edu/~ped/people/faculty/publications_nowak/Nowak_Science06.pdf

Clearly, the ideas are applicable to Swarm Intelligence and Software Agents as well as to theoretical history; a.k.a. Evolutionary Dynamics, a.k.a. historical simulations (think of the the PC game - Age of Empires).

The article, "Group Competition, Reproductive Leveling, and the Evolution of Human Altruism" (Science magazine, 8 December 2006:Vol. 314. no. 5805, pp. 1569 - 1572) by Samuel Bowles discusses similar ideas within the context of human cultural evolution. There we read:

"Humans behave altruistically in natural settings and experiments. A possible explanation—that groups with more altruists survive when groups compete—has long been judged untenable on empirical grounds for most species. But there have been no empirical tests of this explanation for humans. My empirical estimates show that genetic differences between early human groups are likely to have been great enough so that lethal intergroup competition could account for the evolution of altruism. Crucial to this process were distinctive human practices such as sharing food beyond the immediate family, monogamy, and other forms of reproductive leveling. These culturally transmitted practices presuppose advanced cognitive and linguistic capacities, possibly accounting for the distinctive forms of altruism found in our species."

Motto for Software Development

I think the following motto (from the Russian Constructivists) is a pretty good one when applied to software development:


Not The Old, Not The New, Only The Necessary!
