Minimum Gamma Divergence for Regression and Classification Problems

Shinto Eguchi

AI总结:

本书系统介绍最小伽马散度方法,涵盖回归、泊松点过程及机器学习应用,旨在提升统计估计与模型的稳健性和性能。

摘要:

本书分为四个主要章节。第1章介绍散度度量的基础概念,包括著名的Kullback-Leibler散度及其局限性。随后详细探讨了幂散度,如α、β和γ散度,并强调其独特性质与优势。第2章探讨回归模型中的最小散度方法,展示这些方法如何提高统计估计的稳健性和效率。第3章将这些方法扩展到泊松点过程,重点关注生态学应用,为物种分布及其他空间现象的建模提供稳健框架。最后,第4章探讨散度度量在机器学习中的应用,包括Boltzmann机、AdaBoost和主动学习。该章强调这些度量在增强模型稳健性和性能方面的实际益处。

英文摘要:

The book is structured into four main chapters. Chapter 1 introduces the foundational concepts of divergence measures, including the well-known Kullback-Leibler divergence and its limitations. It then presents a detailed exploration of power divergences, such as the $α$, $β$, and $γ$-divergences, highlighting their unique properties and advantages. Chapter 2 explores minimum divergence methods for regression models, demonstrating how these methods can improve robustness and efficiency in statistical estimation. Chapter 3 extends these methods to Poisson point processes, with a focus on ecological applications, providing a robust framework for modeling species distributions and other spatial phenomena. Finally, Chapter 4 explores the use of divergence measures in machine learning, including applications in Boltzmann machines, AdaBoost, and active learning. The chapter emphasizes the practical benefits of these measures in enhancing model robustness and performance.
