Normalized predicted probability distribution for all classes, including the “no planet” (NP) scenario, from the ordered V3 data set after fine-tuning. This figure displays data generated using the same procedure as in Figure 18, with the no planet scenario explicitly shown for clarity. While the orbital period classes exhibit relatively sharp diagonal structure in the confusion matrix, the no planet scenario shows a distinctly different distribution; heavily skewed toward the lowest period bin, as explained in Figure 29.
