Example of EB predictions done by the CNN and FNN SST models over a cutout of the new dataset. The left panel shows the intensity image in the red wing of Hα at +1 Å offset. The middle and right panels show the predictions done by the CNN and FNN models respectively. The colormap indicates the probability assigned by the models to each pixel of being an EB. The white dashed contours mark the 0.1 probability of the CNN prediction and are drawn in all panels to facilitate spatial comparison. An animation of this figure that shows the probability maps over the full time sequence is available in the online material.
