Interpreting Sentiment Composition with Latent Semantic Tree (2023.findings-acl)
Copied to clipboard
| Challenge: | Current researches on sentiment classification are shifting from improving model performance to interpretability. |
| Approach: | They propose a new tree form capable of interpreting sentiment composition in a principled way. |
| Outcome: | The proposed tree can explain sentiment composition in a principled way. |
Shuttle Between Symbolic Instructions and Neural Parameters of Large Language Models (2026.acl-long)
Copied to clipboard
| Challenge: | Despite their distinct external representations, a deeper analysis reveals their intrinsic nature: instructions serve as a natural language compression devised by humans for data governing specific mapping patterns, whereas parameters act as 'neuro compression' of the same task data. |
| Approach: | They propose a neural network framework to model and learn the bi-directional mappings between instructions and parameters of large language models by evaluating it on the tasks of instruction deduction and induction. |
| Outcome: | The proposed framework can map one of the instructions/parameters to the other by evaluating it on the tasks of instruction deduction and induction. |
On the In-context Generation of Language Models (2024.emnlp-main)
Copied to clipboard
| Challenge: | Large language models (LLMs) have the ability of in-context generation (ICG) when given an in-text prompt, they can implicitly recognize the pattern of the examples and complete the prompt in the desired way. |
| Approach: | They propose a plausible latent variable model to model the distribution of pretrained corpora and formalize ICG as a problem of next topic prediction. |
| Outcome: | The proposed model can model the distribution of pretrained corpora and then formalize ICG as a problem of next topic prediction. |
Alignment Rationale for Natural Language Inference (2021.acl-long)
Copied to clipboard
| Challenge: | Existing explanation methods pick prominent features, but alignments between words or phrases are more enlightening clues to explain the model. |
| Approach: | They propose a method to generate alignment rationale explanations for co-attention based models in NLI by feature selection. |
| Outcome: | The proposed method is more faithful and human-readable compared with existing methods. |
MIE: A Medical Information Extractor towards Medical Dialogues (2020.acl-main)
Copied to clipboard
| Challenge: | EMRs are important but many doctors suffer from writing them, which is time-consuming and tedious. |
| Approach: | They propose an automatic conversion of medical dialogues to EMRs using a window-sliding style . they propose a medical information extractor (MIE) that extracts medical information from medical dialogue . |
| Outcome: | The proposed model extracts medical information from doctor-patient dialogues. |

| Challenge: | Experimental results demonstrate that our method significantly outperforms traditional contrastive learning approaches when using the same amount of data. |
| Approach: | They propose a new contrastive learning method built on embedding conditional probability distributions that integrates two tasks: information compression and conditional distribution alignment. |
| Outcome: | The proposed method outperforms traditional contrastive learning approaches and achieves comparable performance to state-of-the-art models when using the same amount of data. |
Generative Calibration for In-context Learning (2023.findings-emnlp)
Copied to clipboard
| Challenge: | In-context learning is one of the most exciting features of large language models . performance is sensitive to various configurations of the prompt, such as the choice or order of the training examples. |
| Approach: | They propose to calibrate the in-context predictive distribution by adjusting the label marginal . they find that the proposed method outperforms the ICL and state-of-the-art calibration methods . |
| Outcome: | The proposed method outperforms state-of-the-art methods by 27% absolute in macro-F1. |
Logic Traps in Evaluating Attribution Scores (2022.acl-long)
Copied to clipboard
| Challenge: | Modern deep learning models are notoriously opaque, which has motivated the development of methods for interpreting how deep models predict. |
| Approach: | They propose to review existing methods for evaluating attribution scores and summarize the logic traps in these methods. |
| Outcome: | The proposed methods show that they do not contain logic traps and that they are not reliable. |
