Local and Global Graph Modeling with Edge-weighted Graph Attention Network for Handwritten Mathematical Expression Recognition
Yejing Xie, Richard Zanibbi, Harold Mouchère
In this paper, we present a novel approach to Handwritten Mathematical Expression Recognition (HMER) by leveraging graph-based modeling techniques. We introduce an End-to-end model…
ColBERT's [MASK]-based Query Augmentation: Effects of Quadrupling the Query Input Length
Ben Giacalone, Richard Zanibbi
A unique aspect of ColBERT is its use of [MASK] tokens in queries to score documents (query augmentation). Prior work shows [MASK] tokens weighting non-[MASK] query terms, emphasiz…
A Study of PHOC Spatial Region Configurations for Math Formula Retrieval
Matt Langsenkamp, Bryan Amador, Richard Zanibbi
A Pyramidal Histogram Of Characters (PHOC) represents the spatial location of symbols as binary vectors. The vectors are composed of levels that split a formula into equal-sized re…
Mathematical Information Retrieval: Search and Question Answering
Richard Zanibbi, Behrooz Mansouri, Anurag Agarwal
Mathematical information is essential for technical work, but its creation, interpretation, and search are challenging. To help address these challenges, researchers have developed…
