ADVENT - Adversarial Entropy Minimization for Domain Adaptation in Semantic Segmentation
Published:
This post describes the recent work on unsupervised domain adaptation for semantic segmentation presented at CVPR 2019. ADVENT is a flexible technique for bridging the gap between two different domains through entropy minimization. Our work builds upon a simple observation: models trained only on source domain tend to produce over-confident, i.e., low-entropy, predictions on source-like images and under-confident, i.e., high-entropy, predictions on target-like ones. Consequently by minimizing the entropy on the target domain, we make the feature distributions from the two domains more similar. We show that our approach achieves competitive performances on standard semantic segmentation benchmarks and that it can be successfully extended to other tasks such as object detection.
