Learning to Make Reasonable Assumptions
We describe a general mechanism for the dynamic learning of default assumptions about unknown parameters in a complex problem. We evaluate the mechanism in the context of scheduling an academic conference, utilizing an existing scheduling system. We show that the assumptions help the system find better schedules in the presence of uncertainty, and further that the assumptions aid the system’s e...
متن کاملGliding saves time but not energy in Malayan colugos.
Gliding is thought to be an economical form of locomotion. However, few data on the climbing and gliding of free-ranging gliding mammals are available. This study employed an animal-borne three-dimensional acceleration data-logging system to collect continuous data on the climbing and gliding of free-ranging Malayan colugos, Galeopterus variegatus. We combined these movement data with empirical...

Unlike conformant planning, which attempts to find a plan under all possible completions of the initial state, an assumption-based plan supports the assertion of additional assumptions about the state of...

Does knowing what one is about to see make it easier to see it? The answer may depend on the source of the knowledge. Participants completed an object detection task in which they made an object-presence or -absence decision to brieflypresented letters. Hearing the letter name prior to the detection task facilitated detection (d’), but seeing a preview of the to-be-detected stimulus did not. Fo...
