ICDAR 2023 (San Jose, Aug.)
Dr. Zanibbi was a Program Co-Chair alongside Gernot Fink, Rajiv Jain, and Koichi Kise. Ayush Kumar Shah participated in the Doctoral Consortium and presented his work on recognizing math from images.
ICDAR 2024 (Athens, Greece)
Ayush Kumar Shah presenting his journal track (ICDAR/IJDAR) paper on the ChemScraper born-digital and visual parsers. This work was a collaboration between computer scientists at RIT and chemists at UIUC through the MMLI NSF AI Institute. Paper: Shah, A.K., Amador, B., Dey, A., Creekmore, M., Ocampo, B., Denmark, S. and Zanibbi, R. ChemScraper: leveraging PDF graphics instructions for molecular diagram parsing, IJDAR 27: 395-414.
Math IR Book
Richard Zanibbi, Behrooz Mansouri (dprl alumnus), and Anurag Agarwal have completed a draft manuscript for Foundations and Trends in Information Retrieval. The final book will appear early in 2025. (draft arxiv link)
(Aug 2024) We welcome Patrick Philippy as a new PhD student this fall. Patrick has been working on the ChemScraper project for the MMLI NSF AI Center while exploring dissertation topics.
(Aug 2024) Bryan Amador and Matt Langsenkamp have released a paper on arXiv regarding 2D pyramidal character histograms, and the use of rectangular regions and level-skipping that improve formula search effectiveness and space efficiency:https://arxiv.org/abs/2408.09283.
(May 2024) The dprl lab's paper on ChemScraper has been accepted to the ICDAR 2024 journal track. The paper describes (1) a fast and accurate technique for parsing born-digital (vector) PDF images, and (2) its use to create training data for a new approach to visual parsing of molecule diagrams in raster images (i.e., pixel-based such as from PNGs). Code is also available. The paper will appear in a special issue of IJDAR.
(May 2024) Internships: This summer PhD student Abhisek Dey is completing an internship with the drug design company Insitro in San Francisco (Daphne Koller is the CEO). Former RA Ming Creekmore will be working until January with Ying Diao's group in the MMLI NSF AI Center at Univ. Illinois Urbana-Champaign, applying AI to improve solar cell designs.
