Researchers have developed new algorithms for Gaussian graphical model selection when data comes from dependent dynamics, rather than independent samples. One approach uses a local edge-testing estimator that can be implemented in parallel and does not require the data chain to fully mix. The second method involves a burn-in and thinning reduction, proving that a subsampled trajectory can approximate independent samples, allowing standard learners to be used. Both methods include finite-sample recovery guarantees and information-theoretic lower bounds on observation time. AI
