| Challenge: | Chain-of-Thought prompting improves the math reasoning capability of large language models. |
| Approach: | They propose a method for attribution of component-level contributions in CoT reasoning using Shapley value and a stratified sampling algorithm that significantly reduces computational complexity. |
| Outcome: | The proposed method reduces computational complexity and provides robust correlations with model performance. |

| Challenge: | Large Language Models (LLMs) have demonstrated their effectiveness in human-guided dialogues, but tasks in the real world are more complex and require greater autonomy from LLMs. |
| Approach: | They propose to characterize LLM-guided conversation into three fundamental components: Goal Navigation, Context Management, Empathetic Engagement and implement an interviewing environment for the evaluation of LLMs. |
| Outcome: | The proposed LLM outperforms baseline LLMs in interviewing quality and autobiography generation quality. |
Bridge the Gap: High-level Semantic Planning for Image Captioning (2020.coling-main)
Copied to clipboard
| Challenge: | Recent image captioning models have improved the multi-modal interaction, such as attention mechanisms. |
| Approach: | They propose a high-level semantic planning mechanism that integrates a semantic reconstruction and an explicit order planning mechanism to bridge the gap between visual and language domains. |
| Outcome: | The proposed model outperforms previous methods and achieves the state-of-the-art performance on MS COCO. |
