The feature importance of the RF model for the sweep frequency data. The x-axis lists the features used in the model, including solar flare characteristics such as solar flare intensity, integral SXR, as well as CME characteristics like linear speed and angular width. The y-axis represents the importance score of each feature, indicating its contribution to the model’s predictions. This figure demonstrates that features such as linear speed, and angular width play significant roles in the RF model’s performance.
