My Ph.D. work at MIT with Alan Willsky studied Gaussian graphical models with small feedback vertex sets. Three threads: message-passing inference, through feedback message passing (Liu et al., 2010; Liu et al., 2012) and its fully distributed, recursive form (Liu & Willsky, 2013); asymptotically exact sampling via stationary and non-stationary subgraph perturbations (Liu et al., 2013; Liu et al., 2015); and structure learning when the feedback nodes are observed or latent (Liu & Willsky, 2013).
