Agents generalize to novel levels of abstraction by using adaptive linguistic strategies (2025.findings-acl)
Copied to clipboard
| Challenge: | Abstract: Abstracts are fundamental to building well-generalizing models. |
| Approach: | They propose to use a concept-level reference game to generalize concepts . they find that agents can learn robust concepts based on which they can generalize . |
| Outcome: | The proposed model can generalize from generic to very specific concepts, while reusing many messages from training. |
Emergence of Hierarchical Reference Systems in Multi-agent Communication (2022.coling-1)
Copied to clipboard
| Challenge: | a hierarchical reference system allows the selection of the most appropriate level of specificity for a given context. |
| Approach: | They propose a hierarchical reference game to study the emergence of hierarchic reference systems in artificial agents. |
| Outcome: | The proposed game shows that agents can generalize to new concepts . the hierarchical reference game is based on a simplified world . |
