Can We Edit Factual Knowledge by In-Context Learning? (2023.emnlp-main)
Copied to clipboard
| Challenge: | In-context knowledge editing (IKE) is a new paradigm for NLP research that can be applied to large language models with tens or hundreds of parameters. |
| Approach: | They propose to use in-context knowledge editing (IKE) without gradient updating to edit factual knowledge without a gradient update. |
| Outcome: | The proposed method achieves a competitive success rate compared to gradient-based methods on GPT-J but with fewer side effects. |

| Challenge: | Existing mathematical verifiers are trained with binary classification labels, which are not informative enough for the model to accurately assess the solutions. |
| Approach: | They propose a natural language feedback-enhanced verifier that can validate the correctness of response generated by policy models by constructing automatically generated training data and a two-stage training paradigm. |
| Outcome: | The proposed verifier significantly improves in verification and reinforcement learning and alleviates data-demanding problems of the reward model. |
Coarse-to-Fine Dual Encoders are Better Frame Identification Learners (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Recent efforts to model frame definitions lack sufficient representation learning of definitions or lack efficient frame modeling. |
| Approach: | They propose a frame-target-encoder architecture that uses coarse-to-fine learning to model alignment between frames and targets. |
| Outcome: | The proposed framework outperforms existing models by 0.93 overall scores and 1.53 R@1 without lf. |

| Challenge: | In-context learning (ICL) is a new paradigm for natural language processing . large language models (LLMs) demonstrate the ability to learn from a few examples . |
| Approach: | They propose to explore ICL to evaluate and extrapolate the ability of large language models. |
| Outcome: | The proposed methods can be used to evaluate and extrapolate the ability of large language models. |
Joint Multi-Decoder Framework with Hierarchical Pointer Network for Frame Semantic Parsing (2021.findings-acl)

| Challenge: | Current researches on frame semantic parsing ignore the interactions among subtasks. |
| Approach: | They propose a multi-decoder strategy to handle these subtasks together . they propose introducing a hierarchical pointer network for argument identification . |
| Outcome: | The proposed architecture improves on state-of-the-art models on FrameNet dataset. |
Can Language Models Understand Physical Concepts? (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing language models do not understand basic physical concepts in the human world. |
| Approach: | They propose a method to transfer embodied knowledge from visual models to LMs . they use visual concepts and embodies concepts learned from interaction with the world . |
| Outcome: | The proposed method achieves comparable performance with scaling up parameters of LMs 134. |
A Double-Graph Based Framework for Frame Semantic Parsing (2022.naacl-main)
Copied to clipboard
| Challenge: | Frame semantic parsing is a fundamental NLP task, which consists of three subtasks: frame identification, argument identification and role classification. |
| Approach: | They propose a frame semantic parser with a double-graph to derive knowledge-enhanced representations for frames and FEs. |
| Outcome: | The proposed method outperforms the state-of-the-art method by up to 1.7 F1-score on two FrameNet datasets. |
