论文摘要

建议系统或称为推荐系统是一种工具,可以帮助用户提供特定困境的建议。因此,最近,在许多领域开发推荐系统的兴趣增加了。模糊逻辑系统(FLSS)是可用于对推荐系统进行建模的方法之一,因为它可以处理不确定性和不精确信息。但是,FLS中的基本问题之一是维度诅咒的问题。也就是说,随着输入变量的数量,FLS中规则的数量正在成倍增加。克服此问题的一种有效方法是使用层次模糊系统(HFSS)。本文旨在探讨HFSS用于推荐系统的使用。具体而言,我们有兴趣根据四个关键标准,即拓扑,规则,规则结构和解释性探索和比较职业路径推荐系统(CPRS)的HFS和FL。调查结果表明,在推荐系统示例的背景下,HFS比FLS具有改善可解释性模型的优势。这项研究有助于提供有关推荐系统中可解释的HFSS发展的见解。

Recommendation system or also known as a recommender system is a tool to help the user in providing a suggestion of a specific dilemma. Thus, recently, the interest in developing a recommendation system in many fields has increased. Fuzzy Logic system (FLSs) is one of the approaches that can be used to model the recommendation systems as it can deal with uncertainty and imprecise information. However, one of the fundamental issues in FLS is the problem of the curse of dimensionality. That is, the number of rules in FLSs is increasing exponentially with the number of input variables. One effective way to overcome this problem is by using Hierarchical Fuzzy System (HFSs). This paper aims to explore the use of HFSs for Recommendation system. Specifically, we are interested in exploring and comparing the HFS and FLS for the Career path recommendation system (CPRS) based on four key criteria, namely topology, the number of rules, the rules structures and interpretability. The findings suggested that the HFS has advantages over FLS towards improving the interpretability models, in the context of a recommendation system example. This study contributes to providing an insight into the development of interpretable HFSs in the Recommendation systems.
