Hidden State Variability of Pretrained Language Models Can Guide Computation Reduction for Transfer Learning (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Existing approaches to transfer a pretrained language model include fine-tuning all the parameters in the language model and adapting all its subsets. |
| Approach: | They propose to select layers based on the variability of their hidden states given a task-specific corpus. |
| Outcome: | The proposed model reduces the computational cost of transfer learning methods without sacrificing performance. |
Learn Like Humans: Use Meta-cognitive Reflection for Efficient Self-Improvement (2026.acl-long)
Copied to clipboard
| Challenge: | Existing self-improving frameworks rely on inefficient, multi-turn recursive loops that incur high computational costs. |
| Approach: | They propose a framework that achieves efficient self-evolution within a single recurrence cycle. |
| Outcome: | The proposed framework outperforms state-of-the-art self-evolving systems while significantly reducing computational overhead. |
Knowledge Graph Embedding with Hierarchical Relation Structure (D18-1)
Copied to clipboard
| Challenge: | Existing knowledge graph embedding models embed entities and relations into latent vectors without leveraging rich information from relation structure. |
| Approach: | They extend existing KGE models to learn knowledge representations by leveraging relation structure . authors say their approach is capable of extending other KGEs . |
| Outcome: | The proposed approach can extend existing KGE models, and validates against baselines. |
