Abstract: We can visually interpret a complex image at a glance. Who is there? What is there? Where is this place? Such recognition requires our brain to reduce the rich and high-dimensional visual information mapped onto the retina into low-dimensional representations that guide the perceptual decision. In the first part of my talk, I will introduce how we can tease apart stimulus information that supports decisions from that which does not, using a data-driven approach. Then I will show you the brain processes related to the two components: 1) reduction of behaviorally irrelevant information, and 2) the construction of behavioral representations. In the second part of my task, I will illustrate the reduced representations enable us to perform an efficient and versatile recognition, using a case study about individual face identification.
