Genetic Algorithms help us to understand how we see

There is a very interesting article on the insciences.org, it talks about the use of a Genetic Algorithm to create images used to test people brain performance:

The team developed a ‘genetic algorithm’, based on a simple model of evolution, that can breed a range of images and visual stimuli which were then used to test people’s brain performance. By using artificial intelligence to design the test patterns, the team removed any likelihood of predetermining the results which could have occurred if researchers had designed the test pictures themselves.

Happy Darwin day !

As Wikipedia says:

Darwin Day is a recently instituted celebration intended to commemorate the anniversary of the birth of Charles Darwin on February 12, 1809. The day is used to highlight Darwin’s contribution to science and to promote science in general.

Today is the bicentenary of Darwin’s birth and the 150th anniversary of the publication of the On the Origin of Species. So, take some time to read.

“I love fools experiments.
I am always making them.

A beautiful example of cooperation between theory and experiment, the new Boron form

The NY Times has a nice article talking about the discovery of a new Boron form using Genetic Algorithms:

Now researchers led by Dr. Oganov have added to the actual discoveries. They have found a form of boron that is nearly as hard as diamond.

This discovery even illustrates the power of the idea of evolution, using a so-called genetic algorithm to decipher the structure of the new boron crystal.

“This work is a beautiful example of cooperation between theory and experiment,” said Aitor Bergara, a physicist at the University of the Basque Country in Spain. Dr. Bergara was not involved with the research, which was published online by the journal Nature.
