| Challenge: | Large language models are increasingly useful for data-centric tasks, but how do we decide how much data to include in the prompt? |
| Approach: | They propose a cluster-then-select prompting technique that adds the most representative rows from the input data to the LLM prompt. |
| Outcome: | The proposed technique outperforms a baseline for tasks with syntactic variation in the input table. |

| Challenge: | Large Language Models (LLMs) can solve increasingly complex NLP tasks such as Excel specific tasks. |
| Approach: | They propose a large-scale benchmark to test whether Large Language Models can generate code that solves Excel specific tasks provided via natural language user instructions. |
| Outcome: | The proposed model outperforms existing models and provides a hard benchmark for state of the art models like GPT-4. |
CodeFusion: A Pre-trained Diffusion Model for Code Generation (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing models for code generation from natural language do not allow reconsidering earlier tokens . prior work has explored grouped beam search or nucleus sampling to generate diverse text. |
| Approach: | They propose a diffusion code generation model that iteratively denoises a program conditioned on the encoded natural language. |
| Outcome: | The proposed model outperforms state-of-the-art models in accuracy and diversity compared to existing models. |
