Mixtures Confidence Map for the mixtures approach: the “confidence map” (a), compared to a similarly timed SUVI 195 Å observation (b). A high value of 1 corresponding (white) in the confidence map indicates the classifier was certain in the labeling while values around 0.5 (black) indicates the classifier found two classes nearly equally likely. This is helpful in the cases of filaments and prominences where the signature compared to quiet Sun is not always clear.
