Unsupervised Learning: Self-aggregation in Scaled Principal Component Space*
We demonstrate that data clustering amounts to a dynamic process of self-aggregation in which data objects move towards each other to form clusters, revealing the inherent pattern of similarity. Selfaggregation i...

Projection-Based Needle Segmentation in 3D Ultrasound Images
Our method is composed of three steps: The 3D image is projected along an initial direction, and the needle is segmented in the projected image. Using the projection direction and detected 2D needle direction,...

Nonnegative Lagrangian Relaxation of K-Means and Spectral Clustering
We show that K-means and spectral clustering objective functions can be written as a trace of quadratic forms. Instead of relaxation by eigenvectors, we propose a novel relaxation maintaining the nonnegativity...

Cluster Aggregate Inequality and Multi-level Hierarchical Clustering
We show that (1) in hierarchical clustering, many linkage functions satisfy a cluster aggregate inequality, which allows an exact O(N 2) multi-level (using mutual nearest neighbor) impleme...
