| Challenge: | Two-Tower Vision-Language models suffer from ineffective layer-by-layer utilization of uni-modal representations and cannot flexibly exploit different levels of unil-modal knowledge. |
| Approach: | They propose a model architecture that gathers and combines the insights of pre-trained uni-modal experts at different levels to facilitate more comprehensive cross-modal alignment and fusion. |
| Outcome: | The proposed model outperforms baselines with and without Vision-Language Pre-training (VLP) with 4M VLP data. |
