Bridging the Visual Gap: Fine-Tuning Multimodal Models with Knowledge-Adapted Captions

NAACL 2025long

Recent research increasingly focuses on training vision-language models (VLMs) with long, detailed image captions. However, small-scale VLMs often struggle to balance the richness of these captions with the risk of hallucinating content during fine-tuning. In this paper, we explore how well VLMs ada…

DeciMamba: Exploring the Length Extrapolation Potential of Mamba

ICLR 2025poster

Long-range sequence processing poses a significant challenge for Transformers due to their quadratic complexity in input length. A promising alternative is Mamba, which demonstrates high performance and achieves Transformer-level capabilities while requiring substantially fewer computational resourc…

Mitigating Open-Vocabulary Caption Hallucinations

EMNLP 2024main

While recent years have seen rapid progress in image-conditioned text generation, image captioning still suffers from the fundamental issue of hallucinations, namely, the generation of spurious details that cannot be inferred from the given image. Existing methods largely use closed-vocabulary objec…
