Beyond ROC-AUC: Operating-Point Performance Reporting for Biometric Verification
Ajan Ahmed, Masudul H. Imtiaz
A biometric verifier is often deployed with a strict false match budget, so only a narrow, low false match rate (FMR) slice of the score range is used. A reporting standard for thi…
Classical Machine Learning Baselines for Deepfake Audio Detection on the Fake-or-Real Dataset
Faheem Ahmad, Ajan Ahmed, Masudul Imtiaz
Deep learning has enabled highly realistic synthetic speech, raising concerns about fraud, impersonation, and disinformation. Despite rapid progress in neural detectors, transparen…
A Comparative Evaluation of Deep Learning Models for Speech Enhancement in Real-World Noisy Environments
Md Jahangir Alam Khondkar, Ajan Ahmed, Stephanie Schuckers +1
Speech enhancement, particularly denoising, is vital in improving the intelligibility and quality of speech signals for real-world applications, especially in noisy environments. W…
