| Challenge: | Emojis are the evolution of characterbased emoticons and are used to express ideas about a myriad of topics. |
| Approach: | They propose a label-wise attention mechanism to better understand emoji prediction . they propose to model e-mails with eojis and then label them based on their meaning . |
| Outcome: | The proposed model improves over baselines and does particularly well when predicting infrequent emojis. |

Exploring Attention Attractors in Large Language Models (2026.acl-long)
Copied to clipboard
| Challenge: | Existing studies have suggested that attention attractors function as "summary tokens" while others speculate that tokens with weaker semantics attract high attention, they act as attention sinks that offload excessive attention. |
| Approach: | They examine attention attractors, tokens that draw significantly high attention, in large language models. |
| Outcome: | The proposed models are able to capture long-range dependencies within a given context. |
