Attributions over IRIS slits. The top panel shows an intensity map (black and white) over the pixels of one of IRIS’s slit positions in time, with darker colors indicating more intense emission. The corresponding saliency map can be seen below, with warmer colors (orange, red etc.) indicating regions that are seen by the models to be important for flare prediction. The black curve in the intensity map corresponds to the GOES-curve whose flare level is indicated on the right axis, while the white curve in the attribution map is the mean prediction score as a function of time along the slit (score seen on the right axis). The bottom panel is the same but for a different observation. Both examples have an increasing prediction score closer to flare onset.
