1/28/2010 – Machine Learning

Welcome to ISUTech, math 120 students. Rather than making a very content heavy post, I thought I’d let you focus on getting getting a hold of things. So check out this really short blurb on a robot which uses Machine learning to teach itself facial expressions.

EinsteinAt first I thought this robot resembled a creepier version of Mark Twain.  This robot, however, is meant to resemble Albert Einstein, and the choice of its appearance isn’t its creator’s alone.  This robot doesn’t choose from facial expressions programmed by humans.  Connected to a video camera, loaded with face recognition software, and placed in front of a mirror, the  robo-Einstein can contort its face randomly until it receives a reward signal.  Armed with this information it can repeat the process, perfecting its facial expressions by matching them to  human responses.  Its developers call the process “body babble.”There are also plans to use the robot to start socializing after that it will be used in automatic tutoring experiments.

That’s all for now, but come back every Monday and Thursday for new posts, and more chances for extra-credit! Remember to take the blackboard quiz, you can read more about the robot here.
