A big silicon brain.Researchers at ATR ATR Achilles tendon reflex, see Ankle reflex laboratories in Kyoto, Japan, are building an "artificial brain." To be completed in 2001, the lab's CAM-Brain Project aims to produce a silicon brain with more than 1 billion artificial neurons, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. Hugo de Garis, an ATR computer scientist. The brain will come in the form of a neural network neural network or neural computing, computer architecture modeled upon the human brain's interconnected system of neurons. Neural networks imitate the brain's ability to sort out patterns and learn from trial and error, discerning and extracting and will exist within a massively parallel See MPP. computer. To create such a complex system, the researchers will have the network build itself. "Cellular automata cellular automata (CA) Simplest model of a spatially distributed process that can be used to simulate various real-world processes. Cellular automata were invented in the 1940s by John von Neumann and Stanislaw Ulam at Los Alamos National Laboratory. ," each one a distinct computer program, will actually forge their own linkages. De Garis calls this approach "evolutionary engineering." The neural net grows when cellular automata send "growth signals" to each other, then connect via "synapses." Currently the brain's logical innards are forming in two dimensions, though they will soon begin to interconnect in three dimensions, de Garis says. Since the network will evolve its own structure, de Garis calls it a type of "Darwin Machine." |
