Solved unsupervised anomaly detection(UAD) by using density estimation
→ Previous methods are difficult to adapt to the change in the normal data's distribution
Proposed Ada-Flow
A unified model of a Normalizing Flow and Adaptive Batch Normalizations
Can be adapted to a new distribution by just conducting forward propagation once per sample
Can be used on devices that have limited computational sample
Confirmed effectiveness of this method through an anomaly detection in a sound task
Also confirmed that our model can be used for the cross-domain translation problem through experiments on image datasets.
