My group has investigated the computational nature of face repres entation and processing in the brain\, by integrating and developing a var iety of machine learning and computer vision methods. We have found that h uman social trait perception has both a linear component and a quadratic c omponent\, with the latter specifically related to the statistical typical ity of a face. We have shown that this typicality element is related to ef ficient coding in feature representation\, with implications for learning and exploration. Moreover\, we find task-dependent attention modifies face feature representation by re-representing faces in the most task-relevant feature subspace\, with predictable consequences on corresponding typical ity/attractiveness judgement. Separately\, we estimate the relative import ance humans assign to different features of the face\, and show that these correspond well to the facial features that best objectively discriminate individuals\, with the caveat that these attentional weights are modified by personal experience with different types of faces. Finally\, I will di scuss how facial processing affects social perception and judgment\, with implications for gender and racial biases.\n DTSTART:20231205T170000Z DTEND:20231205T180000Z SUMMARY:QLS Seminar Series - Angela Yu URL:/qls/channels/event/qls-seminar-series-angela-yu-3 53170 END:VEVENT END:VCALENDAR
