A Transferable Autologistic Model for Predicting Rare Failures in Heterogeneous Equipment
Islam Benamirouche, Djemel Ziou, Feriel Fass
Predicting failures before they occur remains a major challenge in predictive maintenance, particularly when failures are rare, when equipment of the same family differ in sensor c…
Improved image display by identifying the RGB family color space
Elvis Togban, Djemel Ziou
To display an image, the color space in which the image is encoded is assumed to be known. Unfortunately, this assumption is rarely realistic. In this paper, we propose to identify…
Linear Anchored Gaussian Mixture Model for Location and Width Computations of Objects in Thick Line Shape
Nafaa Nacereddine, Aicha Baya Goumeidane, Djemel Ziou
Accurate detection of the centerline of a thick linear structure and good estimation of its thickness are challenging topics in many real-world applications such X-ray imaging, rem…
Hierarchical mixture of discriminative Generalized Dirichlet classifiers
Elvis Togban, Djemel Ziou
This paper presents a discriminative classifier for compositional data. This classifier is based on the posterior distribution of the Generalized Dirichlet which is the discriminat…
Deriving Lehmer and Hölder means as maximum weighted likelihood estimates for the multivariate exponential family
Djemel Ziou, Issam Fakir
The links between the mean families of Lehmer and Hölder and the weighted maximum likelihood estimator have recently been established in the case of a regular univariate exponenti…
