Software engineers as well as
neuroscientists at University of Waterloo, Canada claimed that they have
developed a closest model of the functioning human brain, known as
Spaun which is advanced enough for passing the basic IQ tests. This is
the virtual brain which functions on the supercomputer and comprises of a
digital eye, which can be used for visual input. It also has the
robotic arm which can be used for drawing the response.
The engineers as well as neuroscientists
claimed that this was the most complex model of the world of human
brain. Spaun or Semantic Pointer Architecture Unified Network comprises
of 2.5 million simulated neurons which enables this brain to perform
multiple tasks.
The tasks which this artificial brain
can perform range from answering the questions to copy drawing as well
as fluid reasoning. The tests were conducted in which the engineers and
neuroscientists showed various letters as well as numbers, which were
read in the memory by Spaun. Later, the other symbol or letter behaved
like the command which tells Spaun what needs to be done with the
memory.
