Recall (%) as a function of S/N and DM in the FRB detection model. Each cell shows the recall score achieved in a given (S/N, DM) bin, with warmer colors indicating higher recall. Axes are labeled with S/N ranges (x-axis) and DM ranges in units of pc/cm³ (y-axis). The model demonstrates high recall in most regions, particularly at high S/Ns and intermediate DMs. Performance degrades noticeably at low S/N (≤14) and at both extremes of the DM range (DM < 147 and DM > 857 pc/cm³), likely due to under-representation in training or edge effects in preprocessing.
