How a Computer Program Became Classical Music's Hot, New Composer


University of California, Santa Cruz professor David Cope has developed Emily Howell, a music-composing program that generates its own compositions by following musical rules that Cope has taught it. The program is only fed music composed by an earlier program of Cope's, Experiments in Musical Intelligence. Critics say that Emily's music, while impressive, lacks the ability to trigger emotional reactions in listeners. A 2008 University of Essex study determined that the human brain has a stronger emotional reaction to music played by humans than by machines, even when the listener does not know the source of a performance. Cope says that Emily and other programs capable of artistic creation offer an opportunity for collaboration with human artists, rather than replacing them. "Computers are there [for us] to extend ourselves through them," he says. "It seems so utterly natural to me. It's not like I taught a rock to compose music."

The MEME Suite(software that is mentioned from 24 to 29) allows you to:

* discover motifs using MEME or GLAM2 on groups of related DNA or protein sequences,
* search sequence databases using motifs,
* compare a motif to all motifs in a database of motifs, and
* associate motifs with Gene Ontology terms via their putative target genes

30-motif cluster allows you to analyze motifs in a set of protein sequences, relating them to the alignment, phylogeny, and (where available) the 3D structures. It is useful for detecting remote homologies between protein families, for understanding which proteins are most likely to share functions, and for identifying residue changes that might be important for the evolution of new enzyme activities.

We have limitations?

Hello guys
last week I saw an article with this title "Limitations of human brain mean we may never understand the secrets of universe, says Britain's top scientist", I was surprised how this can be possible, we have limitations but our equipments do not have limitations and also we are able to add extra memory, processor's and so on to our brains who said we can't.
I hope this guy with this nice smile have answers for these issues.

Do you agree with me?

Researchers predict human visual attention using computer intelligence for the first time



Queen Mary, University of London scientists have developed a computer-based model to better understand change blindness--the inability for people to see obvious changes to scenes around them. "The biologically inspired mathematics we have developed and tested can have future uses in letting computer vision systems such as robots detect interesting elements in their visual environment," says Queen Mary professor Peter McOwan. As part of the study, participants were asked to spot the differences between pre-change and post-change versions of a series of pictures. To eliminate bias, the researchers developed an algorithm that enabled the computer determine how to change the images that study participants were asked to view. In addition to being able to predict change blindness, the research showed that the addition or subtraction of an object from the scene is detected more often than changes in the color of the object. The researchers say the model will be useful in designing displays for road signs, emergency services, security, and surveillance to draw attention to a change or part of the display that requires immediate attention.
