Fast Estimation of Pairwise Biharmonic Distance on Graphs
This paper introduces novel methods for efficiently estimating Biharmonic Distance (BD) on large graphs, a critical metric for understanding local and global structural properties in network science, machine learning, and graphics. The authors propose two new formulations for BD based on a "pivot node" and the inverse of the v-grounded Laplacian matrix. These formulations lead to three algorithms: BACKPUSH (deterministic, local propagation), FASTWALK (randomized, collision-counting absorbing random walks), and FASTTREE (sampling spanning trees and aggregating path statistics). Extensive experiments on real-world and synthetic graphs demonstrate that these algorithms consistently outperform state-of-the-art methods (like SWF and RP) in both speed (over 100 times faster) and accuracy, particularly on large, dense networks. The work highlights the importance of leveraging prior structural knowledge and adaptive strategies for efficient large-scale graph analysis.

Experiments
The paper develops two novel formulations for Biharmonic Distance (BD) based on a pivot node, derived through novel proof techniques. These formulations enhance theoretical understanding of BD and enable efficient approximation algorithms. They are based on the inverse of the v-grounded Laplacian matrix and lead to three novel combinatorial views of BD, inspiring the algorithm designs.
Three main algorithms are proposed: BACKPUSH, a deterministic method based on a local pushback operation; FASTWALK, a randomized approach using l-truncated absorbing random walks and collision counting; and FASTTREE, inspired by a novel connection between BD and spanning trees. Each algorithm leverages different structural knowledge for efficiency and versatility across various graph types.
Extensive empirical evaluations on benchmark networks, including those with hundreds of millions of edges, demonstrate that the proposed algorithms consistently outperform state-of-the-art methods. They achieve more accurate solutions over 100 times faster, validating their efficiency and strong accuracy across diverse graph regimes and sizes.

Pivot Node Impact: Degree Centrality
Selecting an optimal pivot node significantly reduces computational cost. Our analysis confirms that highest-degree nodes consistently yield the best or near-best accuracy and fastest runtime, outperforming PageRank and Closeness by a large margin on datasets like Facebook, Road-RA, and Youtube. This choice leverages high node accessibility for random walks and rapid residual absorption in pushback operations, leading to minimized approximation bias.
