mPLUG-DocOwl2: High-resolution Compressing for OCR-free Multi-page Document Understanding

ACL 2025long

Multimodel Large Language Models(MLLMs) have achieved promising OCR-free Document Understanding performance by increasing the supported resolution of document images. However, this comes at the cost of generating thousands of visual tokens for a single document image, leading to excessive GPU memory…

Accommodating Audio Modality in CLIP for Multimodal Processing

AAAI 2023technical

Multimodal processing has attracted much attention lately especially with the success of pre-training. However, the exploration has mainly focused on vision-language pre-training, as introducing more modalities can greatly complicate model design and optimization. In this paper, we extend the state-…

InfoMetIC: An Informative Metric for Reference-free Image Caption Evaluation

ACL 2023long

Automatic image captioning evaluation is critical for benchmarking and promoting advances in image captioning research. Existing metrics only provide a single score to measure caption qualities, which are less explainable and informative. Instead, we humans can easily identify the problems of captio…

Learning Descriptive Image Captioning via Semipermeable Maximum Likelihood Estimation

NeurIPS 2023poster

Image captioning aims to describe visual content in natural language. As 'a picture is worth a thousand words', there could be various correct descriptions for an image. However, with maximum likelihood estimation as the training objective, the captioning model is penalized whenever its prediction m…

MPMQA: Multimodal Question Answering on Product Manuals

AAAI 2023technical

Visual contents, such as illustrations and images, play a big role in product manual understanding. Existing Product Manual Question Answering (PMQA) datasets tend to ignore visual contents and only retain textual parts. In this work, to emphasize the importance of multimodal contents, we propose a…

Movie101: A New Movie Understanding Benchmark

ACL 2023long

To help the visually impaired enjoy movies, automatic movie narrating systems are expected to narrate accurate, coherent, and role-aware plots when there are no speaking lines of actors. Existing works benchmark this challenge as a normal video captioning task via some simplifications, such as remov…

MovieUN: A Dataset for Movie Understanding and Narrating

EMNLP 2022finding

Automatic movie narration generation and narration grounding are very important to provide a true movie experience for the blind and visually impaired. To tell the movie story well, it is necessary to mention plot-related details (such as character names) and keep the narrations in a plot coherent.…
