2. Summary

To establish the reliable early-warning predictions of algal bloom, researching the optimal prediction model between ANN and SVM is carried. Finding the sampling area featured data and selecting the effective prediction interval are also done. Chl-a is predicted for the substitution of direct algal concentrations.

 

When analyzing the prediction accuracies, they are almost the same, but SVM shows better performance than ANN. However, the significant point is SVM explains the sampling area featured data better than ANN. 7 days prediction shows the highest prediction accuracy among three interval predictions.
