New algorithm learns Gaussian graphical models from single trajectory

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a new polynomial-time algorithm capable of recovering the conditional-independence graph of a Gaussian graphical model from a single trajectory of Glauber dynamics. This method does not require the trajectory to reach its mixing time, addressing a gap in current capabilities for temporally correlated observations. The algorithm involves estimating conditional variances, rescaling the trajectory, and employing a local edge test with a robust median-based estimator to ensure accuracy despite temporal dependencies. AI

IMPACT This research advances methods for analyzing complex, temporally correlated data, potentially impacting fields that rely on graphical models for understanding relationships.

    Learning Gaussian Graphical Models from a Glauber Trajectory Without Mixing

    We study the task of learning the structure of a $d$-sparse Gaussian graphical model on $n$ variables from a single trajectory of Glauber dynamics. Beyond algorithmic considerations, many applications present temporally correlated observations rather than i.i.d.\ samples. In the …
