Now, computer scientists from the Machine Perception Laboratory at the University of California, San Diego have used machine learning to enable the robot to learn expressions on its own.

This is called color temperature, and our eye/brain computer is very adept at adjusting our perception so that we hardly notice it.

We now know that the brain is much more malleable and fluidly organized than the analogy to computer hardware suggests, and that it changes with every perception and every action.
