Abstract

Anthropogenic environmental pollution is a known and indisputable issue, and the importance of searching for reliable mathematical models that help understanding the underlying process is witnessed by the extensive literature on the topic. In this article, we focus on the temporal aspects of the processes that govern the concentration of pollutants using typical explanatory variables, such as meteorological values and traffic flows. We develop a novel technique based on multiobjective optimization and linear regression to find optimal delays for each variable, and then we apply such delays to our data to evaluate the improvement that can be obtained with respect to learning an explanatory model with standard techniques. We found that optimizing delays can, in some cases, improve the accuracy of the final model up to 15%.
空气质量建模中的时间因素——以弗罗茨瓦夫为例
人为环境污染是一个众所周知且无可争议的问题,关于该主题的大量文献证明了寻找有助于理解潜在过程的可靠数学模型的重要性。在本文中,我们将使用典型的解释变量(如气象值和交通流量)来关注控制污染物浓度的过程的时间方面。我们开发了一种基于多目标优化和线性回归的新技术来寻找每个变量的最优延迟,然后我们将这些延迟应用于我们的数据,以评估与使用标准技术学习解释模型相比可以获得的改进。我们发现,在某些情况下,优化延迟可以将最终模型的准确性提高15%。

期刊介绍: Air, Soil & Water Research is an open access, peer reviewed international journal covering all areas of research into soil, air and water. The journal looks at each aspect individually, as well as how they interact, with each other and different components of the environment. This includes properties (including physical, chemical, biochemical and biological), analysis, microbiology, chemicals and pollution, consequences for plants and crops, soil hydrology, changes and consequences of change, social issues, and more. The journal welcomes readerships from all fields, but hopes to be particularly profitable to analytical and water chemists and geologists as well as chemical, environmental, petrochemical, water treatment, geophysics and geological engineers. The journal has a multi-disciplinary approach and includes research, results, theory, models, analysis, applications and reviews. Work in lab or field is applicable. Of particular interest are manuscripts relating to environmental concerns. Other possible topics include, but are not limited to: Properties and analysis covering all areas of research into soil, air and water individually as well as how they interact with each other and different components of the environment Soil hydrology and microbiology Changes and consequences of environmental change, chemicals and pollution.
