IBM manufactures chips are designed so that first claimed to have the ability that comes closest to the ability of the human brain. Microprocessor system that can do a “rewiring” the connection when it finds new information, just like the work of synapses in the human nervous system.
Scientists believe, by replicating the human nervous system, the technology can continue to learn. Cognitive computing is developed in this chip will probably be used to understand human behavior and are used for environmental monitoring.
Dhamendra Modha, project leader of IBM explains, now IBM is trying to re-create aspects that exist in humans, such as emotion, perception, cognition, and sensation by a process called “reverse engineering the brain”.
System synapses, thus the name of the system developed by IBM, has two prototype chips neurosinapsis computing. Both have 256 computational cores which, according to scientists in the electronic equivalent of neurons. The chip has 262,144 fixed synapses, while others have 65,536 synapses learners.
In animals and humans, the synapses connecting the brain cells and other nerve parts based on new experiences in life these two creatures. The learning process is essentially the creation and strengthening of synapses that. An engine, of course, can not be soldered onto and detached itself. However, this can be simulated by increasing the volume of the input signal and put less attention on the other.
So far, IBM has not shown in detail how the system works synapses. However, Dr. Richard Cooper, cognitive scientist at Birbeck University of London, said it is possible to replicate the physical connection to the virtual machine. In addition to strengthen and weaken the network, systems such as those developed by IBM to easily remember how much “attention” given to each signal and change the dependence on new experiences.
“Part of the trick is learning algorithms, How do you should turn the volume up and down,” said Dr. Cooper. “There is much work to be done with relatively simple systems such as associate memory. When we see a cat, we may see a little mouse,” continued Cooper.
Some people consider that this technology will reach its peak when the machine consciousness materialized. However, Mark Bishop, professor of cognitive computing warned, “I understand cognition as something more and beyond the process of execution only simulations with computing, such claims are on the verge of a miracle.”
Until now, IBM continues to work on projects together Synapses its academic partners and has just given a 21 million U.S. dollars by the U.S. Defense Advanced Research Projects Agency (DARPA).
