研究针对关系型基础模型处理高基数数据时的窗口限制问题,通过引入合成金融数据集Animus并采用时间预聚合方法,显著提高了预测性能。
Online misinformation detection faces challenges in scalability and reliance on external knowledge. This work proposes a novel method that requires no fine-tuning, retrieval, or task-specific supervision, treating truthfulness as a geometric property within the representation space of pretrained language models. By contrasting activation patterns between true and false statements, the approach identifies a “falsehood direction” in the residual stream and classifies inputs via projection of their final-layer activations. Combining contrastive activation addition (CAA) with an MLP classifier, the method demonstrates strong performance across mainstream architectures—including Gemma, Llama, and Qwen—matching or surpassing zero- and few-shot prompting on benchmarks LIAR and FACTors, with particularly notable gains for smaller models. Its performance is limited on AVeriTeC, which relies on annotated evidence, underscoring the method’s paradigm of evidence-free detection.
