一种通过非凸规划求解随机广义线性回归的新方法

A Novel Approach in Solving Stochastic Generalized Linear Regression via Nonconvex Programming

Vu Duc Anh, Tran Anh Tuan, Tran Ngoc Thang, Nguyen Thi Ngoc Anh

AI总结:

本文提出一种基于非凸规划、聚类和分位数估计的随机广义线性回归求解方法,在F1、精确率和召回率上比普通逻辑回归提升1至2个百分点。

摘要:

广义线性回归(如逻辑回归或泊松回归)是长期研究的回归分析方法,其应用广泛用于各种分类问题。本研究将随机广义线性回归模型视为带机会约束的随机问题,并采用非凸规划技术进行求解。同时使用聚类技术和分位数估计来估计随机数据的均值和方差-协方差矩阵。采用衡量逻辑回归性能的指标来评估模型效果,包括F1分数、精确率分数和召回率分数。在相同数据集上,所提算法在上述评估标准下比普通逻辑回归模型提高了1到2个百分点以上。

英文摘要:

Generalized linear regressions, such as logistic regressions or Poisson regressions, are long-studied regression analysis approaches, and their applications are widely employed in various classification problems. Our study considers a stochastic generalized linear regression model as a stochastic problem with chance constraints and tackles it using nonconvex programming techniques. Clustering techniques and quantile estimation are also used to estimate random data's mean and variance-covariance matrix. Metrics for measuring the performance of logistic regression are used to assess the model's efficacy, including the F1 score, precision score, and recall score. The results of the proposed algorithm were over 1 to 2 percent better than the ordinary logistic regression model on the same dataset with the above assessment criteria.
