Analysis of the currently established Bayesian nearest neighbors classification model points to a connection between the computation of its normalizing constant and issues of NP-completeness. An alternative predictive model constructed by aggregating the predictive distributions of simpler nonlocal models is proposed, and analytic expressions for the normalizing constants of these nonlocal models are derived, ensuring polynomial time computation without approximations. Experiments with synthetic and real datasets showcase the predictive performance of the proposed predictive model.

Article Synopsis
  • The study evaluated arterial stiffness, indicated by pulse wave velocity (PWV), in patients with COPD and those with both COPD and obstructive sleep apnea (OSA), referred to as overlap syndrome (OS).
  • A total of 102 COPD patients were analyzed, with 51 having OSA; both groups were similar in age and airflow limitation, but the OS group had a higher percentage of men.
  • The findings showed that high PWV values were common in both groups, but there were no significant differences in PWV, blood pressure, or other vascular measures between the COPD alone and the COPD with OSA groups.

Local treatment plays a key role for patients' outcome in tumors of the urogenital tract in children. Despite a great variety of different etiologies, the specific localization of pediatric urogenital tumors renders several characteristic demands to the treating personnel. Surgery and radiotherapy are the main elements of local treatment in this group of neoplasms.
