Research ArticleOpen accessIn the keywordsA Modification of the Ridge Type Regression EstimatorsMoawad El-Fallah Abd El-SalamProblem statement: Many regression estimators have been used to remedy multicollinearity problem. The ridge estimator has been the most popular one. However, the obtained estimate is biased. Approach: In this stuyd, we introduce an alternative shrinkage estimator, called modified unbiased ridge (MUR) estimator for coping with multicollinearity problem. This estimator is obtained from Unbiased Ridge Regression (URR) in the same … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,638 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCA-LIME: A Collinearity-Aware LIME Framework for Reliable and Interpretable Explanations in Healthcare AIIdris Khan, Sachin BhoiteIn clinical tabular models, correlated biomarkers can make local explanations unstable even when predictive performance appears acceptable. This paper presents CA-LIME, a collinearity-aware extension of LIME built to address that failure mode directly. Five variations of CA-LIME Vanilla reference, VIF, PCA back projection, Ridge, and ElasticNet allow us to investigate how various correlation-control strategies alter explanation behavior.

Research ArticleOpen accessIn the abstractBone Microarchitecture by Dentistry Digital X-Ray (BµA-DDX) Software: A Pilot Study of the Analysis of Bone Density using Digital Dental X-RaysAdriane Yaeko Togashi, Adair Santa Catarina, Lucas Renato Piana Batistussi, Guilherme CoelhoThe Bone Microarchitecture by Dentistry Digital X-Ray (BµA-DDX) software was designed to determine jaw bone quality using digital dental X-rays. In order to identify patients with a suspicion of low bone density, a system was developed to evaluate bone microarchitecture through the analysis of samples collected in digital panoramic X-rays. The samples were collectedat two sites of the mandible: alveolar … …Current Research in Dentistry, Vol. 6, Issue 2 · 23 Feb 2016 · 7,471 accessesView PDF Cite
