The GMT offsets shown reflect the offsets at the moment of the conference.

Time Band

By setting a time band, the program will dim events that are outside this time window. This is useful for (virtual) conferences with a continuous program (with repeated sessions).
The time band will also limit the events that are included in the personal iCalendar subscription service.

Abstract

Carefully reifying the differential-geometric pushforward and pullback operators as forward and reverse AD clarifies the relationship between forward and reverse AD, and allows the formalization of AD of higher-order functions. We discuss the relationship between the differential-geometric constructs and the usual practice of just lifting all reals to duals, focusing on how they differ in the case of higher-order functions.
