Overview

In this paper, we present a novel Cross-Modal Adapter for parameter-efficient fine-tuning. Although surprisingly simple, our approach has three notable benefits: (1) reduces 99.6% of fine-tuned parameters, and alleviates the problem of overfitting, (2) saves approximately 30% of training time, and (3) allows all the pre-trained parameters to be fixed, enabling the pre-trained model to be shared across datasets.

Results

1.Text2video and video2text retrieval resutls on MSR-VTT.

2. Text2video and video2text retrieval resutls on MSVD, VATEX, DiDeMo, and ActivityNet.

3. Training efficiency.

4. Visualizations.
