Towards Understanding the Relation between Gestures and Language (2022.coling-1)
Copied to clipboard
| Challenge: | a new study explores the relationship between gestures and language . we use contrastive learning to learn gesture embeddings . |
| Approach: | They adapt a semi-supervised multimodal model to learn gesture embeddings using Ted talks . they show gestures are predictive of the native language of the speaker . |
| Outcome: | The proposed model learns gesture embeddings from a multimodal dataset . it shows that gesture embeds are predictive of the native language of the speaker . |
Masked Diffusion Captioning for Visual Feature Learning (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Unlike autoregressive captioning, the strength of the visual learning signal in MDC does not depend on each token’s position in the sequence, reducing the need for auxiliary objectives. |
| Approach: | a decoder conditioned on visual features is trained to reconstruct the original text. |
| Outcome: | masked diffusion captioning (MDC) is a form of image-conditioned captioning that can be applied to visual tasks. |
