Recall (%) across the S/N and DM bins for a threshold variant of the FRB detection model. The x-axis shows the S/N ranges, while the y-axis indicates DM ranges in units of pc/cm³. Each cell is color-coded by recall score and annotated with its value. The model maintains strong performance at high S/N (≥20) across all DM bins, with near-perfect recall above S/N=20. However, performance drops at lower S/N, particularly in the 10–14 range, and at the lowest and highest DM ranges (DM < 147 and DM > 857 pc/cm³), where recall can fall below 80%.
