Abstract
In recent years, large-scale pre-trained multimodal models (LMMs) generally
emerge to integrate the vision and language modalities, achieving considerable
success in multimodal tasks, such as text-image classification. The growing
size of LMMs, however, results in a significant computational cost for
fine-tuning these models for downstream tasks. Hence, prompt-based interaction
strategy is studied to align modalities more efficiently. In this context, we
propose a novel efficient prompt-based multimodal interaction strategy, namely
Efficient Prompt Interaction for text-image Classification (EPIC).
Specifically, we utilize temporal prompts on intermediate layers, and integrate
different modalities with similarity-based prompt interaction, to leverage
sufficient information exchange between modalities. Utilizing this approach,
our method achieves reduced computational resource consumption and fewer
trainable parameters (about 1\% of the foundation model) compared to other
fine-tuning strategies. Furthermore, it demonstrates superior performance on
the UPMC-Food101 and SNLI-VE datasets, while achieving comparable performance
on the MM-IMDB dataset.
