Positional Bias in Multimodal Embedding Models: Do They Favor the Beginning, the Middle, or the End?

AAAI 2026technical

Positional bias—where models overemphasize certain positions regardless of content—has been shown to negatively impact model performance across various tasks. While recent research has extensively examined positional bias in text generation models, its presence and effects in representation models r

FineLIP: Extending CLIP's Reach via Fine-Grained Alignment with Longer Text Inputs

CVPR 2025poster

As a pioneering vision-language model, CLIP (Contrastive Language-Image Pre-training) has achieved significant success across various domains and a wide range of downstream vision-language tasks. However, the text encoders in popular CLIP models are limited to processing only 77 text tokens, which c…

Semantic Segmentation Based on Multiple Granularity Learning

IROS 2023poster

Accurate and robust coarse semantic segmentation plays a key role in the pursuit of autonomous driving. We present an algorithm that regularizes the representation space of Semantic Segmentation by Multiple Granularity Learning (SSMGL). This approach explores multiple levels of semantic knowledge in…
