Spectral Clustering using PCKID - A Probabilistic Cluster Kernel for Incomplete Data
2017 · arXiv (Cornell University)
In this paper, we propose PCKID, a novel, robust, kernel function for spectral clustering, specifically designed to handle incomplete data. By combining posterior distributions of Gaussian Mixture Models for incomplete data on different scales, we …

The expressive power of pooling in Graph Neural Networks
2023 · arXiv (Cornell University)
In Graph Neural Networks (GNNs), hierarchical pooling operators generate local summaries of the data by coarsening the graph structure and the vertex features. While considerable attention has been devoted to analyzing the expressive power of …
