Cross-Modal Retrieval Augmentation for Multi-Modal Classification (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Recent advances in using retrieval components over external knowledge sources have shown impressive results for a variety of downstream tasks in natural language processing. |
| Approach: | They propose a retrieval-augmented multi-modal transformer architecture for embedding images and captions in the same space. |
| Outcome: | The proposed approach improves visual question answering over strong baselines and hot-swapping indices. |
When in Doubt: Improving Classification Performance with Alternating Normalization (2021.findings-emnlp)
Copied to clipboard
| Challenge: | a classifier that uses a nonparametric post-processing step for classification suffers when given examples that are close to its decision boundary. |
| Approach: | They propose a nonparametric post-processing step that re-adjusts predicted class probability distributions using high-confidence validation examples. |
| Outcome: | The proposed method improves classifier accuracy on difficult examples. |
