2. Summary

This paper was written to predict the water quality using a machine learning method with time-series data. Data were pretreated by IGRA, used for making feature selection, learned by LSTM, used for predicting time-series data. Besides, for the comparison of prediction accuracy, the BP network and ARIMA were introduced.

In the results, IGRA showed the more suitable feature selection results, compared with the advanced researches. And, LSTM displayed the lowest RMSE, compared with the others. For progressing the future researches, enough water quality data are required. Added, GPU having high performance, would be needed to decrease the analyzing time.


3. Originality and Creativity

IGRA method was introduced in this paper to make feature selection for the LSTM model. Using this method, researchers can select the input parameters optimally.
