Evaluating Image Hallucination in Text-to-Image Generation with Question-Answering

AAAI 2025technical

Despite the impressive success of text-to-image (TTI) models, existing studies overlook the issue of whether these models accurately convey factual information. In this paper, we focus on the problem of image hallucination, where images created by TTI models fail to faithfully depict factual content…

Accurate Retraining-free Pruning for Pretrained Encoder-based Language Models

ICLR 2024poster

Given a pretrained encoder-based language model, how can we accurately compress it without retraining? Retraining-free structured pruning algorithms are crucial in pretrained language model compression due to their significantly reduced pruning cost and capability to prune large language models. How…
