例说高职数学建模常见的数据预处理方法

Demonstration on Common Data Preprocessing Methods of Mathematical Modeling in Higher Vocational Institutes by Examples

数据预处理是确保数学建模质量必不可少的步骤,因此在数学建模课程学习过程中应得到重点关注。对竞赛赛题的阐述结果表明高职学生在数学建模过程中常见的数据预处理方法主要有数据清理、数据的归一化处理以及建模对象的量化等。

Data preprocessing is an indispensable step to ensure the quality of mathematical modeling,so should be paid more attention to in the course of learning mathematical modeling.Demonstration on contest questions showed that data preprocessing methods commonly used by higher vocational students in the process of mathematical modeling include data cleaning,data normalization,quantification of modeling objects,etc.
