Holographic Memory Fails Zero-Shot Compositional Reasoning in Knowledge Graphs

Researchers have investigated the effectiveness of Holographic Reduced Representations (HRR) and Fourier HRR (FHRR) for zero-shot compositional reasoning in knowledge graphs. While these methods show promise and are competitive in predicting single-hop links, they fail to compose zero-shot queries. The study found that the primary bottleneck is not the binding or unbinding algebra or the cleanup mechanism, but rather the inherent difficulty in retrieving facts that are part of compositional chains due to capacity and interference effects within the superposed memory.

IMPACT Identifies a fundamental limitation in current knowledge graph embedding models for compositional reasoning, suggesting future research needs to focus on improving retrieval capacity under superposition.
