Dynamically Mitigating Data Discrepancy with Balanced Focal Loss for Replay Attack Detectioncs.CV

Paper proposes D3M to improve anti-spoofing detection by balancing loss function and using complementary features.

problem Improving automatic speaker verification systems against high-quality playback attacks.

method D3M uses a balanced focal loss function to dynamically scale loss based on sample traits, and combines three feature types for robust detection.

result D3M systems outperform conventional methods significantly, achieving min-tDCF of 0.0124 and EER of 0.55%.
