Before revision:  The performance of our approach is demonstrated in both simulated and real data sets, and with a comparison of existing methods. Real application results include learning causality among climate variables in Thailand where our findings can explain known relations among air pollutants and weather variables.
After revision:  The performance of our approach is demonstrated in both simulated and real data sets, and in comparison with an existing method. When applied to two real application results ( learning causality among climate variables in Thailand where our findings can explain known relations among air pollutants and weather variables.
