Machine learning-based prediction of harmful algal blooms in water supply reservoirs

چکیده

Abstract Harmful algal blooms (HABs) pose a potential risk to human and ecosystem health. HAB occurrences are influenced by numerous environmental factors; thus, accurate predictions of HABs explanations about the required implement preventive water quality management. In this study, machine learning (ML) algorithms, i.e., random forest (RF) extreme gradient boosting (XGB), were employed predict in eight supply reservoirs South Korea. The use synthetic minority oversampling technique for addressing imbalanced improved classification performance ML algorithms. Although RF XGB resulted marginal differences, exhibited more stable presence data imbalance. Furthermore, post hoc explanation technique, Shapley additive was estimate relative feature importance. Among input features, temperature concentrations total nitrogen phosphorus appeared important predicting occurrences. results suggest that algorithms along with methods increase usefulness predictive models as decision-making tool

Models of Harmful Algal Blooms

Models used to study harmful algal blooms are a subset of those used to examine more general planktonic processes. Most models have been heuristic, examining the likelihood of certain processes generating a harmful algal bloom. Several models have been more closely coupled to field data and have been used to gain insights into the dynamics underlying the observations. As better physical and bio...

Molecular tools for monitoring harmful algal blooms.

The world's oceans cover 70 % of the Earth's surface, and their dominant populations, both numerically and biomasswise, belong to microscopic protists and prokaryotes. The marine phytoplanktons are major components of both groups and are, by definition, high dispersal taxa with large population sizes. Small photosynthetic organisms are responsible for the bulk of primary production in oceanic a...
