WebApr 27, 2024 · This study offers an approach to cluster small geographies based upon features found to be relevant to COVID-19 propagation. These clusters have greater amounts of data available for further modeling. To accomplish this, a large array of county-level data is collected for the 48 conterminous United States (US). WebTo overcome it, we introduce a new clustering method, referred to as Sparse Convex Clustering, to simultaneously cluster observations and conduct feature selection. The key idea is to formulate convex clustering in a form of regularization, with an adaptive group-lasso penalty term on cluster centers. To optimally balance the trade-off between ...
