Fast Estimation of Wasserstein Distances via Regression on Sliced Wasserstein Distances

Khai Nguyen, Hai Nguyen, Nhat Ho

We address the problem of efficiently computing Wasserstein distances for multiple pairs of distributions drawn from a meta-distribution. To this end, we propose a fast estimation…

Enhancing Retrieval Augmented Generation with Hierarchical Text Segmentation Chunking

Hai Toan Nguyen, Tien Dat Nguyen, Viet Ha Nguyen

Retrieval-Augmented Generation (RAG) systems commonly use chunking strategies for retrieval, which enhance large language models (LLMs) by enabling them to access external knowledg…

Lightspeed Geometric Dataset Distance via Sliced Optimal Transport

Khai Nguyen, Hai Nguyen, Tuan Pham +1

We introduce sliced optimal transport dataset distance (s-OTDD), a model-agnostic, embedding-agnostic approach for dataset comparison that requires no training, is robust to variat…

Towards Marginal Fairness Sliced Wasserstein Barycenter

Khai Nguyen, Hai Nguyen, Nhat Ho

The sliced Wasserstein barycenter (SWB) is a widely acknowledged method for efficiently generalizing the averaging operation within probability measure spaces. However, achieving m…
