GryphOne: Symbol-Aware Masked Diffusion for Structural Refinement in Offline Handwritten Mathematical Expression Recognition
Takaya Kawakatsu, Ryo Ishiyama
Handwritten mathematical expression recognition (HMER) requires reasoning over diverse symbols and structures, yet autoregressive models struggle with exposure bias and syntax inco…
Revisiting Structural Dependency in Autoregressive Multi-Task Table Recognition via Order-Independent Cell-Level Representations
Takaya Kawakatsu
Multi-task table recognition jointly addresses table structure prediction, cell localization, and cell content recognition within a unified framework. Existing approaches often rel…
Hierarchical Modeling Approach to Fast and Accurate Table Recognition
Takaya Kawakatsu
The extraction and use of diverse knowledge from numerous documents is a pressing challenge in intelligent information retrieval. Documents contain elements that require different…
Multi-Cell Decoder and Mutual Learning for Table Structure and Character Recognition
Takaya Kawakatsu
Extracting table contents from documents such as scientific papers and financial reports and converting them into a format that can be processed by large language models is an impo…
