Although achieving promising performance, recent analyses show that current generative large language models (LLMs) may still capture dataset biases and utilize them for generation, leading to poor generalizability and harmfulness of LLMs. However, due to the diversity of dataset biases and the over-optimization problem, previous prior-knowledge-based debiasing methods and fine-tuning-based debiasing methods may not be suitable for current LLMs. To address this issue, we explore combining active learning with the causal mechanisms and propose a casual-guided active learning (CAL) framework, which utilizes LLMs itself to automatically and autonomously identify informative biased samples and induce the bias patterns. Then a cost-effective and efficient in-context learning based method is employed to prevent LLMs from utilizing dataset biases during generation. Experimental results show that CAL can effectively recognize typical biased instances and induce various bias patterns for debiasing LLMs.

Police in Washington state announced two suspects were arrested in connection with the murder of a missing elderly man who was allegedly poisoned with fentanyl by a pair who gained his trust through a dating app. The Mercer Island Police released a statement saying Philip J. Brewer, 32, and Christina Hardy, 47, are facing charges for the murder of Curtis Engeland, 74, by using an elaborate scheme to defraud and murder him. Police said that Brewer and Hardy are believed to have become acquainted with Engeland several months ago and subsequently financially defrauded him. Police also believe the suspects later violently confronted Engeland at his Mercer Island home in the late evening hours of February 23, and used Engeland's vehicle to leave Mercer Island that night.
