The Geometry of Generalized Likelihood Ratio Test [PDF]
Entropy, 2022 The generalized likelihood ratio test (GLRT) for composite hypothesis testing problems is studied from a geometric perspective. An information-geometrical interpretation of the GLRT is proposed based on the geometry of curved exponential families.

Likelihood-Ratio-Based Biometric Verification [PDF]
IEEE Transactions on Circuits and Systems for Video Technology, 2004 This paper presents results on optimal similarity measures for biometric verification based on fixed-length feature vectors. First, we show that the verification of a single user is equivalent to the detection problem, which implies that for single-user verification the likelihood ratio is optimal.

Examining performance and likelihood ratios for two likelihood ratio systems using the PROVEDIt dataset. [PDF]
PLoS ONE, 2021 A likelihood ratio (LR) system is defined as the entire pipeline of the measurement and interpretation processes where probabilistic genotyping software (PGS) is a piece of the whole LR system. To gain understanding on how two LR systems perform, a total

Performance Evaluation of Source Camera Attribution by Using Likelihood Ratio Methods [PDF]
Journal of Imaging, 2021 Performance evaluation of source camera attribution methods typically stop at the level of analysis of hard to interpret similarity scores. Standard analytic tools include Detection Error Trade-off or Receiver Operating Characteristic curves, or other ...
