Looking Back – and AheadThis final chapter reconsiders the ten desiderata for the new framework that were presented in Chapter . and summarizes how they have been satisfied in the chapters that followed. The chapter concludes with a list of remaining problems and areas for future research.缓解 发表于 2025-3-23 19:22:13
Rendite, Risiko und Markteffizienzbasic features shared by most such models: Belief states are represented by logically closed sets of sentences, commonly called belief sets. Changes take the form of either introducing a new sentence into the belief set while retaining consistency (revision) or removing a sentence from it without adMuffle 发表于 2025-3-24 00:49:54

In this chapter the focus is on the selection mechanisms that are used to determine which previous beliefs are retained and which are given up in operations of change. In the AGM model, such epistemic choices are assumed to be performed in two steps (the seSpangle 发表于 2025-3-24 02:49:15

Shared Services for Smaller Entitiester, the new model is constructed from its basic components. We begin with a skeletal input-output model that contains no sentences but only primitive (i.e., unstructured) belief states and inputs, together with a revision function . that takes us from any belief state . and input . to a new belief沙漠 发表于 2025-3-24 13:40:59

In one of these variants, the choice function is based on a relation on belief sets that can be interpreted as representing distances from the current belief set. In another, descriptor revision is constructed from a blockage r强有力 发表于 2025-3-24 17:35:37
