| Challenge: | Recent advances in prompt engineering have created impediments for end users to adopt . however, prompt engineering remains an impedance due to rapid advances in models, tasks, and associated best practices. |
| Approach: | They propose to define APO as a 5-part unifying framework and categorize all relevant works based on their salient features. |
| Outcome: | The proposed framework aims to improve the performance of large language models on various tasks. |
LaRS: Latent Reasoning Skills for Chain-of-Thought Reasoning (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods require human experts or pre-trained LLMs to describe the skill to guide the selection. |
| Approach: | They propose a new approach that uses unsupervised learning to create a latent space representation of rationales with a variable called a reasoning skill. |
| Outcome: | Empirical results show that LaRS outperforms SOTA skill-based selection methods . it processes example banks four times faster and reduces LLM inferences by half . |
