摘要:

在水质管理过程中,识别和解释特征(如位置和天气变量元组)与水质变量(如细菌水平)之间的关系是获得见解和确定应采取干预措施的领域的关键。需要有一个搜索过程,以确定影响水质的现象的位置和类型,并需要解释水质如何受到影响,哪些因素最相关。本文讨论了这两个问题。开发了一种用于收集特征数据的过程,所述特征表示空间区域上的各种变量并且用于训练模型和推断。使用模型和Shapley值对功能的性能进行分析。Shapley值起源于合作博弈论,可用于帮助解释机器学习结果。使用几种机器学习算法和都柏林大运河流域的水质数据进行评估。

英文摘要:

With water quality management processes, identifying and interpreting relationships between features, such as location and weather variable tuples, and water quality variables, such as levels of bacteria, is key to gaining insights and identifying areas where interventions should be made. There is a need for a search process to identify the locations and types of phenomena that are influencing water quality and a need to explain how the quality is being affected and which factors are most relevant. This paper addresses both of these issues. A process is developed for collecting data for features that represent a variety of variables over a spatial region and which are used for training models and inference. An analysis of the performance of the features is undertaken using the models and Shapley values. Shapley values originated in cooperative game theory and can be used to aid in the interpretation of machine learning results. Evaluations are performed using several machine learning algorithms and water quality data from the Dublin Grand Canal basin.
