student-teacher feature pyramid matching for anomaly detection

Training

python Main.py -model {STPM} -loss_function {MKD} -Class {bottle}

Experiment setting

  • STPM

    • Teacher : Pretrained ResNet18
    • Student : ResNet18
    • Loss : MSE (normalized Feature)
  • MKD

    • Teacher : Pretrained Vgg16
    • Student : smaller Vgg16
    • Loss : MSE + Cosine Similarity
  • 모델과 Loss function을 제외하곤 모두 동일한 세팅에서 진행, AUROC 계산 방식, Optimizer ,Learning rate 모두 동일하게 사용

  • Metric으로는 AUROC 를 사용

실험 결과

모델에 따른 성능 비교

Loss function에 따른 성능 비교

  • STPM
    • MSE (normalized)
  • MKD
    • MSE + Cosine similarity
