Machine Learning for Reclassification of Obesity

Overview

The goal of this study is to employ or develop computational modeling techniques for the precise reclassification of obesity into subgroups. Clinical features, risks of noncommunicable diseases, as well as weight loss effects of bariatric surgery will also be studied and compared within the subgroups.

Full Title of Study: “Data-driven Clustering for Metabolic Classification of Obesity Using Machine Learning”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Retrospective
  • Study Primary Completion Date: April 30, 2020

Interventions

  • Diagnostic Test: AI classification of patients with obesity
    • Computational modeling techniques will be used for the precise reclassification of obesity into four subgroups, several variables according to the clinical experience and the modeling results will be selected for the cluster analysis.
