How a Brain-inspired Theory May Solve Problems of Big Data

Anglesey, UK, June 21, 2014 /PressReleasePing/ – We think of supercomputers as being super-powerful. But they can be overwhelmed by the floods of information now produced in science, commerce, government, meteorology, social media, and other areas. And compared with the human brain, they gobble up lots of energy and take up lots of space.

But the human brain may provide some answers in the shape of an SP machine, based on the SP theory of intelligence, which is itself based on research into the workings of brains and nervous systems. This new thinking about “Big data and the SP theory of intelligence”–developed by Dr Gerry Wolff of CognitionResearch.org–has now been published in the journal IEEE Access [Note 1].

“We can save a lot of energy by using probabilities” said Dr Wolff. “Instead of doing computations mechanically, we can concentrate our efforts where answers are most likely to be found. We don’t need some special process for gathering information about probabilities because, as a by-product of how the SP system works, it creates a statistical model of its environment.”

Big savings may also be possible in transmitting things like TV programmes. With some further development, the SP system may learn general rules and patterns from that kind of information. If the transmitter of a TV programme, and TV sets, all know those rules and patterns, then a TV programme can be transmitted economically by sending only the parts that are different from the general rules and patterns.

The SP system may help to bring some order into the chaos of different ways in which knowledge is represented in computer systems. In just one area–the representation of images–there are many different formats–JPEG, TIFF, WMF, BMP, GIF, EPS, PDF, PNG, PBM, and more–and each one has its own special mode of processing. “This jumble of different formalisms and formats for knowledge is a great complication in the processing of big data, especially in processes for the discovery or learning of structures and associations in big data.” said Dr Wolff. The SP system may help to simplify things by serving as a universal framework for the representation and processing of diverse kinds of knowledge (UFK).

The SP system may also help in such things as recognising patterns in big data, reasoning about big data, and in presenting structures and processes in visual forms that would help people undersand big data.

“A useful step forward in developing these ideas would be the creation of a high-parallel version of the SP machine” said Dr Wolff. “This would be based directly on the existing SP computer model, it would be hosted on an existing high-performance computer, and it would provide a means for researchers everywhere to see what can be done with the system and to create new versions of it.”

Majestic Birds of Prey

I learned so much about birds today. The current New Scientist sheds light on their senses. They gave this example of the Great Grey Owl, with ears offset asymmetrically on the skull at 2 and 7 o’clock. The differential timing and volume allows it to pinpoint prey, even when the rodent is scurrying in tunnels under snow.

“Intriguingly, the hearing ability of birds living in temperate climes fluctuates through the year. The auditory regions of their brains grow during the breeding season, then shrink when song becomes less important. Understanding this process could provide clues to treating Alzheimer’s and other neurodegenerative diseases.”

“Another important difference between bird and human hearing occurs in the inner ear, and especially in the cochlea – the structure containing the vibration-sensitive "hearing" hairs. It is snail-shaped in humans, hence its name, whereas in birds it is banana-shaped. In both, the hair cells detect changes in pressure and transform these into electrical signals, which are interpreted as sound in the brain. Crucially, we cannot replace damaged hair cells, making deafness a scourge in older people. Birds, have no such problem: they can grow new hair cells. If we can discover the genetic basis underpinning this difference, it could give us the potential to solve a common cause of age-related hearing loss.”

But how about their vision system? New Scientist on the bird’s eye view:

“Raptors can see to distances far greater than we can. One reason for this is that the light-sensitive layer at the back of our eyes, the retina, has one fovea, a sensitive spot where the image is sharpest. Raptors, in contrast, have two foveae in each eye, which is equivalent to a camera having both a telephoto and a macro lens.”

Are you predator or prey? Eyes facing forward for the hunt, or to the side to detect inbound threats? It gets a lot more complicated than that, with differing functions for each eye. See below…
