The principal is a fairly general account of the inductive bias that allows an observer to reconstruct distal phenomenon from an impoverished proximal data. This principle has been advanced particularly in vision research as an account of how, for example, three-dimensional structure is extracted from an inadequate two-dimensional projection. The principal of generic views has been discussed by Richards and Hoffman, and has been given a sophisticated Bayesian formalization by Freeman. ==Relation to Bayesian inference== Another expression of the generic views principal is that the inference of distal structure should be such that the inference would remain substantially the same if the "position" of the observer were moderately altered (perturned). If the inference made would have been qualitatively or categorically different under a perturbation of the observer, then the inference does not satisfy the generic views assumption, and should be rejected. (The question of what constitutes a qualitative or categorical difference is an interesting point of detail.) On this view, it can be argued that the principal of generic views is nothing more than an inference based on the maximum posterior probability (MAP) which accounts for aspects of observation. Thus, we infer the distal phenomenon which possess the highest probability of having generated the observations in question, and this probability incorporates (in addition to relevant priors) both the likelihood of the distal phenomenon generating certain observable signals, and the likelihood of the observer transducing those signals in a manner consistent with the observations. On such an analysis (and with various assumptions invoked), one can obtain a behavior approximating the generic views principal. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Generic views」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
