遲滯研究:人類認知與時間序列預測

Abstract

遲滯是自然界常見的現象，在工程應用上是極不易處理的問題，引起許多 研究者的興趣，也有許多假設和數學模型被提出。本論文則從另二個方向 來探討遲滯現象，希望能更了解遲滯的特性，藉以提升遲滯系統的效能。 第一個研究主要是探討遲滯現象在人類知覺的存在性，以及和人類知覺的 關係。從研究中，我們可以得知，遲滯的程度和人類可知覺的範圍成正比 。另一個研究則是加入一個遲滯轉換單元，以提高倒傳遞網路在遲滯系統 的建模能力。 Hysteresis phenomenon is frequently observed in the nature.In engineering applications,hysteresis is usually a difficult problem to deal with.Since many researchers are interested in hysteresis problem domain,there have been some hypotheses and mathematical models forhysteresis modeling.In this thesis,we study hysteresis phenomenon from two perceptivesin order to understand the hysteresis properties in more detail,such that we may promote the performance of hysteresis system.In our first study,we find that human perception expresses obviously hysteresis phenomenon onthe changing of color and speed.The sequent study identifies the direct proportion between human preceptiverange and hysteresis degree.In the final study,we add a hysteresis transducer to multilayer feedforward network, Consequently, the performance of hysteresis modeling is successfully improved.
