Flag Variety

1.1. QCoh on a stack. We know that QCoh forms a stack, i.e., sheaf of groupoids, over Schfpqc(S) for any scheme S. Thus if we have an fpqc sheaf of groupoids X over S, we can define QCoh(X ) as maps of sheaves X → QCoh on Schfpqc(S). By 2-Yoneda, this definition agrees with the usual notion of quasicoherent sheaves if X is a scheme. For various other (usually equivalent) definitions in the case...

Action Variety of Planners: Cognitive Load and Requisite Variety

The complexity of planning tasks have increased over the past decade. There is relatively poor understanding what the implications are of increased task complexity in planning and scheduling operations. Previous work in the behavorial sciences have investigated the concept of cognitive load, addressing both task complecity and task workload or stress, and have concluded that decision makers ten...

Variety Amnesia: Recalling Past Variety Can Accelerate Recovery from Satiation

Consumers frequently consume items to the point where they no longer enjoy them. In a pilot study and two experiments spanning three distinct classes of stimuli, we find that people can recover from this satiation by simply recalling the variety of alternative items they have consumed in the past. And yet, people seem to exhibit “variety amnesia” in that they do not spontaneously recall this pa...

Exploiting variety-dependent Phones in Portuguese Variety Identification

This paper presents a new approach of building a language identification system using a specialized Phone Recognition system followed by Language Modeling (PRLM) to differentiate Portuguese varieties spoken in African Countries from European Portuguese. The system is designed to focus on exploiting the phonotactic information of a single discriminatively trained tokenizer for the specific pair ...
