AppBench: Planning of Multiple APIs from Various APPs for Complex User Instruction (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing state-of-the-art Large Language Models (LLMs) still cannot perform well in this situation even with the help of in-context learning and finetuning. |
| Approach: | They propose a benchmark to evaluate LLMs’ ability to plan and execute multiple APIs from various sources in order to complete the user’s task. |
| Outcome: | The proposed benchmarks show that the existing state-of-the-art LLMs still cannot perform well in this situation even with in-context learning and finetuning. |
An End-to-End Submodular Framework for Data-Efficient In-Context Learning (2024.findings-naacl)
Copied to clipboard
| Challenge: | Recent advances in natural language tasks leverage the emergent In-Context Learning ability of pretrained Large Language Models (LLMs). |
| Approach: | They propose a framework for exemplar selection for in-context learning that uses a pool-based active learning approach to select Diverse and informative exemplars from the target tasks’ unlabeled pool. |
| Outcome: | The proposed framework outperforms existing methods for data annotation and similarity-based methods for test query-specific exemplar retrieval on 7 different NLP datasets and 5 LLMs of varying complexities. |

| Challenge: | Recent studies have attempted to enhance the performance of large language models (LLMs) in complex question-answering (QA) tasks by combining step-wise planning with external retrieval. |
| Approach: | They propose a framework for enhancing LLMs’ planning capabilities by using planning data derived from knowledge graphs (KGs). |
| Outcome: | The proposed framework improves LLMs’ planning capabilities by using knowledge graphs (KGs) the proposed framework is compared with existing frameworks on multiple datasets and shows that it is effective for large language models. |
Less is More: Making Smaller Language Models Competent Subgraph Retrievers for Multi-hop KGQA (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Recent studies suggest that Knowledge Graphs (KGs) contain valuable external knowledge for LLMs. |
| Approach: | They propose to model a conditional subgraph retrieval task handled by small language models and use a subgraph identifier as a special token to retrieve subgraphs. |
| Outcome: | The proposed model achieves competitive retrieval performance compared to state-of-the-art models relying on 7B parameters. |

| Challenge: | Large-scale generative language models such as GPT-3 are competitive few-shot learners. |
| Approach: | They train multilingual generative language models on a corpus covering a diverse set of languages and study their few- and zero-shot learning capabilities. |
| Outcome: | The proposed model outperforms GPT-3 on 171 out of 182 directions with 32 training examples and surpasses the official supervised baseline in 45 directions. |
Improving Sequential Model Editing with Fact Retrieval (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods to fix erroneous knowledge in Pre-trained Language models experience a performance decline when the number of edits increases. |
| Approach: | They propose a framework that leverages factual information to enhance editing generalization and guide the identification of edits by retrieving related facts from the fact-patch memory. |
| Outcome: | The proposed framework can improve model generalization and accuracy even with thousands of edits. |

| Challenge: | Existing evaluations of LLMs in finance are text-only, monolingual, and largely saturated by current models. |
| Approach: | They propose a multilingual and multimodal benchmark for evaluating LLMs in real financial contexts. |
| Outcome: | The first expert-annotated multilingual and multimodal benchmark is released . it evaluates 21 leading LLMs and shows they perform better in multilingual settings . |

| Challenge: | Existing approaches to generate text radiology reports are prone to errors and poor clinical accuracy. |
| Approach: | They propose a two-step pipeline that subdivides the problem into factual triple extraction followed by free-text report generation. |
| Outcome: | The proposed pipeline shows that the generated reports exhibit realistic style but lack clinical accuracy. |
Controllable Chest X-Ray Report Generation from Longitudinal Representations (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Radiology reports are detailed text descriptions of the content of medical scans. |
| Approach: | They propose a method to align, concatenate and fuse the current and prior visual information into a joint longitudinal representation which can be provided to a multimodal report generation model. |
| Outcome: | The proposed method achieves state-of-the-art results while enabling anatomy-wise controllable report generation. |
