| Challenge: | Existing approaches for multi-objective Reinforcement Learning (RL) are difficult due to plurality of preferences and applications. |
| Approach: | They propose a framework for finetuning language models on multiple objectives using conditional language policy. |
| Outcome: | The proposed framework outperforms and Pareto-dominates existing approaches for multi-objective Reinforcement Learning (RL) it does not require training or maintaining multiple models to achieve different trade-offs between the objectives. |
Seamlessly Integrating Factual Information and Social Content with Persuasive Dialogue (2022.aacl-main)
Copied to clipboard
| Challenge: | Persuasive dialogue systems are designed for chatbots to communicate with and influence users with specific goals. |
| Approach: | They propose a modular dialogue system framework that integrates factual information and social content into persuasive dialogues. |
| Outcome: | The proposed framework is generalizable to any dialogue tasks that have mixed social and task contents. |
What Do Language Models Learn in Context? The Structured Task Hypothesis. (2024.acl-long)
Copied to clipboard
| Challenge: | Pre-trained large language models have exhibited an impressive ability to learn in context across various domains, e.g., code generation, education, medicine and even medicine. |
| Approach: | They taxonomize existing candidate theories into three competing hypotheses that explain LLMs’ ability to learn in context. |
| Outcome: | The proposed model can learn a task from in-context examples presented in a demonstration and generalize it to the prompt. |
