- This paper suggested a methodology to predict concentration of cyanotoxins using support vector machines (SVM) and multilayer perceptron networks (MLP).
- The data used for the SVM and MLP consisted of 8 biological variables and 15 physical-chemical input variables.
- Cross validation was used for finding a suitable set of hyper parameters of SVM and MLP.
- The SVM with the radial basis kernel function (RBF-Kernel) is showed the best performance for predicting the concentration of cyanotoxins in the Trasona reservoir.
- Two dominant species of the cyanobacteria had synergistic behavior on the increase of cyanotoxins concentration.
3. Application to research
- The cross validation is the standard technique to find a suitable set of hyper parameters of machine learning.
- The significance of each biological and physical-chemical variables on the concentration of cyanotoxins is presented through the results of this paper.
- The sensitivity analysis is essential to optimize the input variables of machine learning and to provide a scientific basis for selecting variables.
