2. cs.LGProcess then Retrieve: Investigating the Origins of the Modality Gap in Vision-Language ModelsArpita Shanbhag, Julia Tran, Dhruv Mandala, Ayda Sultan

   The study investigates why image and language features in vision-language models can be unevenly aligned. Its analysis suggests that text representations need more early processing than image representations, offering a possible explanation for this mismatch.
