TILOS-SDSU Seminar: Challenging Estimation Problems in Vehicle Autonomy

San Diego State University 5500 Campanile Dr, San Diego

Rajesh Rajamani, University of Minnesota Abstract: This talk presents some interesting problems in estimation related to vehicle autonomy. First, a teleoperation application in which a remote operator can intervene to control an autonomous vehicle is considered. Fundamental challenges here include the need to design an effective teleoperation station, bandwidth and time-criticality constraints in wireless communication, […]

TILOS Seminar: Unlearnable Facts Cause Hallucinations in Pretrained Language Models

HDSI 123 and Virtual 3234 Matthews Ln, La Jolla

Adam Tauman Kalai, OpenAI Abstract: Pretrained language models (LMs) tend to preserve many qualities present in their training data, such as grammaticality, formatting, and politeness. However, for specific types of factuality, even LMs pretrained on factually correct statements tend to produce falsehoods at high rates. We explain these “hallucinations” by drawing a connection to binary […]
