Chain-of-Probe: Examining the Necessity and Accuracy of CoT Step-by-Step

NAACL 2025findings

Current research found the issue of Early Answering in large language models (LLMs), where the models already have an answer before generating the Chain-of-Thought (CoT). This phenomenon suggests a potential lack of necessary dependency between the predicted answer and the reasoning process. Consequ…

DPDLLM: A Black-box Framework for Detecting Pre-training Data from Large Language Models

ACL 2024findings

The success of large language models (LLM) benefits from large-scale model parameters and large amounts of pre-training data. However, the textual data for training LLM can not be confirmed to be legal because they are crawled from different web sites. For example, there are copyrighted articles, pe…

JoTR: A Joint Transformer and Reinforcement Learning Framework for Dialogue Policy Learning

COLING 2024main

Dialogue policy learning (DPL) aims to determine an abstract representation (also known as action) to guide what the response should be. Typically, DPL is cast as a sequential decision problem across a series of predefined action candidates. However, such static and narrow actions can limit response…

ReadPrompt: A Readable Prompting Method for Reliable Knowledge Probing

EMNLP 2023long findings

Knowledge probing is a task to assess the knowledge encoded within pre-trained language models (PLMs) by having the PLM complete prompts such as "Italy is located in \_\_,". The model's prediction precision serves as a lower bound for the amount of knowledge it contains. Subsequent works explore tra…
