A Semantic Cover Approach for Topic Modeling

2019

We introduce a novel topic modeling approach based on constructing a semantic set cover for clusters of similar documents. Specifically, our approach first clusters documents using their Tf-Idf representation, and then covers each cluster with …

Leveraging Blockchain for Immutable Logging and Querying Across Multiple\n Sites

Blockchain has emerged as a decentralized and distributed framework that\nenables tamper-resilience and, thus, practical immutability for stored data.\nThis immutability property is important in scenarios where auditability is\ndesired, such as in maintaining access logs for sensitive …

SCE: Scalable Consistency Ensembles Make Blackbox Large Language Model Generation More Reliable

2025 · arXiv (Cornell University)

Large language models (LLMs) have demonstrated remarkable performance, yet their diverse strengths and weaknesses prevent any single LLM from achieving dominance across all tasks. Ensembling multiple LLMs is a promising approach to generate reliable responses …
