New algorithms tackle Gaussian graphical model selection from dependent data

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

    Local and Mixing-Based Algorithms for Gaussian Graphical Model Selection from Glauber Dynamics

    arXiv:2412.18594v3 Announce Type: replace-cross Abstract: Gaussian graphical model selection is usually studied under independent sampling, but in many applications observations arise from dependent dynamics. We study structure learning when the data consist of a single trajector…
