New method uses tensor networks to recover discrete probability distribution graphs

Researchers have developed a novel method for reconstructing the moral graph of discrete probability distributions using fully connected tensor networks (FCTNs). This approach incorporates nuclear-norm-regularized bond corrections, where each bond matrix is adjusted with a low-rank correction. The method proves that under specific assumptions, an optimal FCTN with zero reconstruction error will precisely match the moral graph. For approximate scenarios, the technique provides recovery bounds based on the continuity of conditional mutual information, offering a direct way to interpret the effective graph from optimized bond matrices.
