Adaptive Second Order Coresets for Data-efficient Machine Learning
2022 · arXiv (Cornell University)
Training machine learning models on massive datasets incurs substantial computational costs. To alleviate such costs, there has been a sustained effort to develop data-efficient training methods that can carefully select subsets of the training examples …

Lazier Than Lazy Greedy
2015
Is it possible to maximize a monotone submodular function faster than the widely used lazy greedy algorithm (also known as accelerated greedy), both in theory and practice? In this paper, we develop the first linear-time …

Beyond Semantic Entropy: Boosting LLM Uncertainty Quantification with Pairwise Semantic Similarity
2025
Hallucination in large language models (LLMs) can be detected by assessing the uncertainty of model outputs, typically measured using entropy.Semantic entropy (SE) enhances traditional entropy estimation by quantifying uncertainty at the semantic cluster level.However, as …
