주요 논문
CW-BASS: Confidence-Weighted Boundary Aware Learning for Semi-Supervised Semantic Segmentation
Ebenezer Tarubinga, Jenifer Kalafatovich, Seong-Whan Lee
Tackled boundary blur and confirmation bias using confidence-weighted and boundary-focused techniques. Achieved 65.9% mIoU on Cityscapes with only 100 labeled images.
FARCLUSS: Fuzzy Adaptive Rebalancing and Contrastive Uncertainty Learning for Semi-Supervised Semantic Segmentation
Ebenezer Tarubinga, Jenifer Kalafatovich, Seong-Whan Lee
Introduced fuzzy labels and lightweight contrastive learning to improve generalization in semi-supervised semantic segmentation.
