We then discuss algebraic operations on strategy and their effects, establishing a formal way to generate, combine, select, and improve strategy. We use financial time series as example, and we focus on the study of methods based on our model and show that the algebraic operation on these strategies indeed behave as predicted. We seek to give a more abstract and general theory on strategic decision making, in hope to avoid the various constraints and assumptions needed for classical decision model (which often are not satisfied in financial data). In doing so, we have a more robust system that adapts to model change quickly, react to anomalies correctly, and we are able to bring various different models proposed in the past under an unifying context to compare, and do model selection. Since the theory is widely applicable in various disciplines, this thesis will give a prototype on the system design that reflects intuitively from the mathematical theory, which can be conveniently modified to fit your particular need. We will also test on real world data to demonstrate its strength. URI: http://etd.lib.nctu.edu.tw/cdrfb3/record/nctu/#GT070456506http://hdl.handle.net/11536/141135 Appears in Collections: Thesis
