| Challenge: | Existing approaches to improve the reasoning performance of large language models rely on intuitive instance-level feedback, which limits the reasoning capabilities. |
| Approach: | They propose a framework that pushes LLMs toward System-2-like critic capability by using a step-wise CoT reasoning paradigm and automatic construction of weak-supervision data without human annotation. |
| Outcome: | The proposed model significantly improves task-solving performance by filtering out invalid solutions or iterative refinement. |

Copied to clipboard
| Challenge: | Existing document understanding models focus on key information and generate answers straightforwardly . existing models ignore evidence from source documents and lack interpretability . |
| Approach: | They propose a visual encoder that fuses text into visual encoded visual encodes . they use multimodal large language models as data generators and checkers to generate step-wise question-and-answer pairs for document images. |
| Outcome: | The proposed model can answer step-wise questions without compromising the performance of the original model. |
Type-Driven Multi-Turn Corrections for Grammatical Error Correction (2022.findings-acl)

Generating Major Types of Chinese Classical Poetry in a Uniformed Framework (2020.lrec-1)
Copied to clipboard
| Challenge: | Chinese classical poetry is one of the most valuable literary and cultural heritages of China . it has many particular characteristics in its language structure, ranging from form, sound to meaning . a proposed uniformed framework for generating major types of Chinese classical poems is proposed . |
| Approach: | They propose a uniformed framework for generating major types of Chinese classical poems . they use a form- stressed weighting method to strengthen the control to the form of the generated poems a proposed framework is incorporated into Jiuge, the most influential Chinese classical poetry generation system developed by Tsinghua University. |
| Outcome: | The proposed framework can generate Chinese classical poems of major types with high quality in form and content. |
End-to-end Adversarial Sample Generation for Data Augmentation (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods for generating adversarial samples have deceived many neural inference models, such as text classification and machine translation. |
| Approach: | They propose an adversarial sample generator that consists of a conditioned paraphrasing model and a condition generator and introduce a pretrained discriminator to help the adversarial sample generator adapt to the data characteristics. |
| Outcome: | The proposed approach improves the performance of the trained model on several tasks and is robust for various attacking techniques. |
Investigating and Mitigating Object Hallucinations in Pretrained Vision-Language (CLIP) Models (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing studies have revealed that Large Vision-Language Models suffer from hallucinations in practice, including object hallucines, spatial hallucinos, attribute hallucinications, etc. |
| Approach: | They propose to use CLIP model to mitigate object hallucinations by using a data augmentation method to create negative samples with a variety of hallucinian issues. |
| Outcome: | The proposed method mitigates object hallucinations and can be used as a visual encoder, effectively alleviating the object halluination issue in LVLMs. |
