Recipro-CAM: Fast gradient-free visual explanations for convolutional neural networks

1 code implementation28 Sep 2022 Seok-Yong Byun, Wonju Lee

To overcome this issue, Score-CAM and Ablation-CAM have been proposed as gradient-free methods, but they have longer execution times compared to CAM or Grad-CAM based methods, making them unsuitable for real-world solution though they resolved gradient related issues and enabled inference mode XAI.

Unsupervised Model Drift Estimation with Batch Normalization Statistics for Dataset Shift Detection and Model Selection

no code implementations1 Jul 2021 Wonju Lee, Seok-Yong Byun, Jooeun Kim, Minje Park, Kirill Chechil

While many real-world data streams imply that they change frequently in a nonstationary way, most of deep learning methods optimize neural networks on training data, and this leads to severe performance degradation when dataset shift happens.
