Scatter Plot from Scientific Research

The x-axis indicates observed mean PM2.5in the monitor stations; the y-axis indicates estimated mean PM2.5by the deep ensemble machine learning model in 10-fold cross-validation analysis; the points represent the corresponding PM2.5for both observed and predicted values. There are 9 289 613 datapoints for daily PM2.5, 434 122 for monthly PM2.5, and 38 488 for annual PM2.5; the red line represents a regression line (simple linear regression) for the observed and predicted PM2.5.R2=coefficient of determination for the unseen independent data in 10-fold cross-validation analysis. RMSE=root mean square error.
