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.

A generalized likelihood ratio test for monitoring profile data. [PDF]
J Appl Stat, 2021 Profile data emerges when the quality of a product or process is characterized by a functional relationship among (input and output) variables. In this paper, we focus on the case where each profile has one response variable Y, one explanatory variable x, and the functional relationship between these two variables can be rather arbitrary.

Generalized Likelihood Ratio Test for Adversarially Robust Hypothesis Testing [PDF]
IEEE Transactions on Signal Processing, 2022 Machine learning models are known to be susceptible to adversarial attacks which can cause misclassification by introducing small but well designed perturbations. In this paper, we consider a classical hypothesis testing problem in order to develop fundamental insight into defending against such adversarial perturbations.

Segmentation Method for Ship-Radiated Noise Using the Generalized Likelihood Ratio Test on an Ordinal Pattern Distribution [PDF]
Entropy, 2020 Due to the diversity of ship-radiated noise (SRN), audio segmentation is an essential procedure in the ship statuses/categories identification. However, the existing segmentation methods are not suitable for the SRN because of the lack of prior knowledge.

Cancelable ECG Biometrics Using Compressive Sensing-Generalized Likelihood Ratio Test
IEEE Access, 2019 Electrocardiogram (ECG) has been investigated as promising biometrics, but it cannot be canceled and re-used once compromised just like other biometrics.

When Is The Generalized Likelihood Ratio Test Optimal? [PDF]
Proceedings. 1991 IEEE International Symposium on Information Theory, 1992 Summary: The generalized likelihood ratio test (GLRT), which is commonly used in composite hypothesis testing problems, is investigated. Conditions for asymptotic optimality of the GLRT in the Neyman-Pearson sense are studied and discussed. First, a general necessary and sufficient condition is established, and then based on this, a sufficient ...
