Abstract

Abstract: Quotient space theory is a new kind of mathematical tool for researching the world with different grain sizes. In the theory, a problem is represented as a triplet （X，f，T）, including the universe Ｘ, its structure Ｔ and attributes 　　　ｆ（．） . The world with different grain sizes is described by analyzing the triple （X，f，T）, which has a complete theoretical base. This paper discusses the construction and the computation of quotient space, and the application for yield forecast. Finally, the experimental result is satisfied.

Key words: quotient space, granularity, structure, yield prediction

摘要： 商空间理论是研究不同粒度世界的一种新的数学工具。它用三元组（X，f，T）描述一个问题，其中X 表示问题的论域，f（．）是论域属性，Ｔ是论域的结构。通过分析求解问题（X，f，T），对论域Ｘ及其有关的结构、属性进行深入分析和研究，从而完成不同粒度世界的描述，并有着完整的理论基础。该文主要描述了商空间粒度的构建和计算并应用于农作物产量的预测，通过实验取得了很好的确定结果。
