• SIR is trained in a one-shot universal design by mixing exactly one normal sample from each of nine heterogeneous datasets.method 90%
  Evidencepartial

  The framework adopts a one-shot universal design: a single model is trained by mixing exactly one normal sample from each of nine heterogeneous datasets, enabling effective anomaly detection on all corresponding test sets without task-specific retraining.
