2. Summary

This research is carried to devise a comprehensive water prediction model using an artificial intelligence model (ANN), using multivariate statistical techniques such as PCA, and Non-linear Autoregressive (NAR) model. The historical data of water quality with a 6-minutes time interval for 5 months for 4 parameters (DO, Specific Conductance, Chlorophyll, and DO) are used to input data.

 

In the results of modeling, though all the parameters show high prediction accuracies, in the case of specific conductance, there is overfitting for the training data. Therefore, the adequate balance between bias and variance is needed to improve this model, afterward.

 

3. Application to research

- Time-series data analysis will be needed to predict the future.
