UltraTWD: Optimizing Ultrametric Trees for Tree-Wasserstein Distance

ICML 2025poster

The Wasserstein distance is a widely used metric for measuring differences between distributions, but its super-cubic time complexity introduces substantial computational burdens. To mitigate this, the tree-Wasserstein distance (TWD) offers a linear-time approximation by leveraging a tree structure;…

Boosting Spectral Clustering on Incomplete Data via Kernel Correction and Affinity Learning

NeurIPS 2023poster

Spectral clustering has gained popularity for clustering non-convex data due to its simplicity and effectiveness. It is essential to construct a similarity graph using a high-quality affinity measure that models the local neighborhood relations among the data samples. However, incomplete data can le…

Online estimation of similarity matrices with incomplete data

UAI 2023poster

The similarity matrix measures pairwise similarities between a set of data points and is an essential concept in data processing, routinely used in practical applications. Obtaining a similarity matrix is typically straightforward when data points are completely observed. However, incomplete observa…
