I've just come across the cover article for this month's Seed Magazine. It deals with an attempt to model a human brain using a supercomputer that was built from the ground up for the purpose. The article provides a glimpse into what appears to be the cutting edge of AI research. After the break, a short excerpt explains the general scientific rationale for the project, indicates how the neuroscientists working on it are approaching it intellectually, and outlines the direction it's currently moving in.
"Neuroscience is a reductionist science. It describes the brain in terms of its physical details, dissecting the mind into the smallest possible parts. This process has been phenomenally successful. Over the last 50 years, scientists have managed to uncover a seemingly endless list of molecules, enzymes, pathways, and genes. The mind has been revealed as a Byzantine machine. According to Markram, however, this scientific approach has exhausted itself. "I think that reductionism peaked five years ago," he says. "This doesn't mean we've completed the reductionist project, far from it. There is still so much that we don't know about the brain. But now we have a different, and perhaps even harder, problem. We're literally drowning in data. We have lots of scientists who spend their life working out important details, but we have virtually no idea how all these details connect together. Blue Brain is about showing people the whole...[Markram says] You can have all the data in the world, but without a model the data will never be enough." I guess "because it will be a lot of fun" doesn't fly on grant proposals. It's great to see that we're making strides toward the HAL9000, and only just a few years behind schedule. |
