| Metric Representations: Algorithms and Geometry | Algorithmic Advances for Statistical Inference with Combinatorial Structure | 2021-10-11 |
Shows that corrupted pairwise distances (e.g., 5% bad edges wrecking an Isomap embedding) are repairable by optimizing over the metric polytope; introduces… | ||
| Sparse Metric Repair: If It Ain't Broke, Don't Fix It | Societal Networks 2018 | 2018-03-26 |
Problem: a symmetric nonnegative distance matrix violates triangle inequalities; goal is to find a perturbation P so D+P is a metric while minimizing the L0… | ||
| Inferring Structural Properties: Graphs and Bridges | Workshop on Succinct Data Representations and Applications (Simons Institute Big Data 2013) | 2013-09-16 |
Wireless sensors sample bridge vibration and modal shapes are recovered by taking an SVD of the time-by-sensor matrix after aggressive sketching. Using… | ||
