Semantic Uncertainty Quantification of Hallucinations in LLMs: A Quantum Tensor Network Based Method

ICLR 2026poster

Large language models (LLMs) exhibit strong generative capabilities but remain vulnerable to confabulations, fluent yet unreliable outputs that vary arbitrarily even under identical prompts. Leveraging a quantum tensor network–based pipeline, we propose a quantum physics-inspired uncertainty quantif…

Inferring latent states in a network influenced by neighbor activities: An undirected generative approach

ICASSP 2017accepted

The problem of inferring the hidden state of individual nodes in social/sensor networks in which node activities affect their neighbors is growing in importance. We present an undirected generative model, a type of probabilistic model that has so far not been used for modeling latent variables influ…
