Published: Cluster Analysis for Identifying Obesity Subgroups in Health and Nutritional Status Survey Data
MSc in Computer Science student, Usman Khalil has published research in Asia-Pacific Journal of Information Technology and Multimedia (APJITM). Well done!
Usman Khalil, MSc in Computer Science, co-supervised by Dr Owais Malik and Dr Daphne Lai has published his paper, Cluster Analysis for Identifying Obesity Subgroups in Health and Nutritional Status Survey Data, at the Asia-Pacific Journal of Information Technology and Multimedia (APJITM). This research was a collaboration with Dr Ong Sokking, Ministry of Health, Brunei. His masters project was in the investigation of machine learning techniques to identify meaningful patterns in the health and nutritional survey data.
Excerpt of abstract:
“This study presents the discovery of meaningful patterns (groups) from the obese samples of health and nutritional survey data by applying various clustering techniques. Due to the mixed nature of the data (qualitative and quantitative variables) in the data set, the best-suited clustering techniques with appropriate dissimilarity metrics were chosen to interpret the meaningful results. The relationships between obesity and the lifestyle affecting factors like demography, socio-economic status, physical activity, and dietary behavior were assessed using four cluster techniques namely Two-Step clustering, Partition Around Medoids (PAM), Agglomerative Hierarchical clustering and, Kohonen Self Organizing Maps (SOMs).”
