Monitoring Neural Training with Topology: A Footprint-Predictable Collapse Index

Alexander Kalinowski

Representational collapse, where embeddings become anisotropic and lose multi-scale structure, can erode downstream performance long before performance metrics react. We propose an…

Calibrated Persistent Homology Tests for High-dimensional Collapse Detection

Alexander Kalinowski

We study detection of collapse in high-dimensional point clouds, where mass concentrates near a lower-dimensional set relative to a non-collapsed geometry. We propose persistent ho…

Repurposing Knowledge Graph Embeddings for Triple Representation via Weak Supervision

Alexander Kalinowski, Yuan An

The majority of knowledge graph embedding techniques treat entities and predicates as separate embedding matrices, using aggregation functions to build a representation of the inpu…

Exploring Wasserstein Distance across Concept Embeddings for Ontology Matching

Yuan An, Alex Kalinowski, Jane Greenberg

Measuring the distance between ontological elements is fundamental for ontology matching. String-based distance metrics are notorious for shallow syntactic matching. In this explor…
