DiFA: Dual Evidence Fusion and Aggregation for Token-Level Text Anomaly Detection
arXiv:2609.22136v1 Announce Type: new Abstract: Text anomaly detection, the task of identifying text instances that deviate from normal language patterns, is crucial for language-driven applications. However, most existing methods can only perform document-level anomaly detection, making it hard to…
