CovNet: Covariance Networks for Functional Data on Multidimensional Domains

By Soham Sarkar and Victor Panaretos
Covariance estimation is ubiquitous in functional data analysis. Yet, the case of functional observations over multidimensional domains introduces computational and statistical challenges, rendering the standard methods effectively inapplicable. To address this problem, we introduce "Covariance Networks" (CovNet) as a modeling and estimation tool. The CovNet model is "universal" - it... Show more
