Fig. 5From: Modeling equatorial ionospheric vertical plasma drifts using machine learningRegression Plots Comparing SF99 Versus Our Machine Learning Model; Scatter plots for actual measurements versus predictions using the SF99 model (green) and machine learning model (red) at 250 km (left), 360 km (middle), and 500 km (right). Each panel shows the coefficient of determination (\(R^2\)) and the RMSE values for the machine learning and SF99 modelsBack to article page
