Prediction of toxic algae and biotoxin presenceusing machine learning techniques

In this thesis, it is aimed to reveal the correlation between the toxic algae species and the biotoxin detected in shellfish such as mussels in seawater analysis. In addition, the effect of water and mussel analysis on this situation was examined. The accumulation of biotoxins in mussels is a serious danger for people who consume mussels. Estimation of the presence of biotoxin and toxic phytoplankton is also the basis of this study. Time is needed to meet production conditions and high expenditure is required for sea water and mussel analyzes. In this study, it is thought that these expenditures can be prevented by estimating the presence of biotoxin and toxic phytoplankton. Estimates made here are made by machine learning techniques. For this study, a data of approximately 3 years has been discussed. Physical, chemical and biological analysis results of samples from mussel and water is available in the data content. An imbalance is observed in the current data. In other words, the presence of biotoxin is very rare. This is called imbalanced data in the literature. Therefore, after the data was stabilized, machine learning studies were carried out. As a result of the studies, the most successful estimation was obtained by the Random Forest method.
