Intelligent Control and Cognitive Systems Perception and Memory in Cognitive Systems Joanna J. Bryson University of Bath, United KingdomAbout the Course(work) Course was designed as MSc level. • One of its deliverables is engaging you • with research (both reading & writing.) Informed public, citizen science. • Exam a concession to final-year • dissertations. …so, a bit about research (& coursework.) •Time Management and Degree Outcomes Most of you are writing dissertations. 100 hours/course / 12 weeks/course (8.3 hours/week - 2 hours/week) 3 week/coursework 19 hours/coursework. 5 writing up 14 hours to hackDoing Research First you need to get your hands dirty. Learn about the problem domain. Check to see whether you have an approach that might work. Publishable projects are normally preceded by pilot projects.What’s Worth Doing? At this point, should run with something you have. Normally – look at literature for controversies you might take a side on. Test which side is right. Google Scholar – who cited a paper you’re interested in, and why?Writing Up Research Any paper can have only one point. Point is in the Intro & Conclusion. Results prove the conclusion; Approach & Discussion explain the Results. Pick a point / claim you think will be most promising to talk about, then examine it in detail..Which Point? What surprised you? What did you need to learn to get your robot working? Is there something your robot does better than the others? Could you teach others to do it? Look for “tricks” / lessons learned; think about the Brooks contribution.Intelligent Control and Cognitive Systems brings you... Perception and Memory in Cognitive Systems Joanna J. Bryson University of Bath, United KingdomSensing vs Perception First week: Sensing – what information • comes in. This week: Perception – what you think is • going on. Perception includes expectations. • Necessary for disambiguating noisy and • impoverished sensory information.What Would Nature Touch input Do? Ear input Eye inputBasic Natural Input CPU Actually whole thing • computes & senses. Processing Signal takes time to • (accumulation) propagate, one cell may get two messages from same axon. Many different types • & configurations of nerve cells. OutputHow Eyes WorkHow (Vertebrate) Eyes Work Lens focuses world on back of eye. • Rods & cones (receptors) respond to light • falling on them. Bipolar cells combine information, detect • edges & gradients. Ganglian cells aggregate bipolar cells. •Ganglian cells detect changes in colour, brightness. Send this information to the back of the brain.Excitation, Inhibition & Feature Detection c.f. Mann linkInformation Projected and Accumulated Visual cortex has retinotopic maps responding to different edges, motions.Associative Cortices Features • aggregated into objects.
