Scatter plot illustrating sources predicted as TDEs by the transient branch within the unlabeled dataset. The x-axis denotes the predicted probability of being a TDE, while the y-axis indicates the second-highest predicted probability. The dashed gray line signifies a 1:1 ratio, where points closer to this line suggest greater uncertainty by the classifier about the true class of the source. Additionally, the histogram shows the distribution of the second-highest probability class labels relative to the orthogonal distances from the dashed line, highlighting the classifier’s confusion concerning the actual classes of the sources.
