• Title: Compensation Learning in Semantic Segmentation
• Authors: Timo Kaiser, Christoph Reinders, Bodo Rosenhahn
• Abstract summary: We propose Compensation Learning in Semanticscapes, a framework to identify and compensate ambiguities as well as label noise. We introduce a novel uncertainty branch for neural networks to induce the compensation bias only to relevant regions. Our method is employed into state-of-the-art segmentation frameworks and several experiments demonstrate that our proposed compensation learns inter-class relations.

• Abstract: Label noise and ambiguities between similar classes are challenging problems in developing new models and annotating new data for semantic segmentation. In this paper, we propose Compensation Learning in Semantic Segmentation, a framework to identify and compensate ambiguities as well as label noise. More specifically, we add a ground truth depending and globally learned bias to the classification logits and introduce a novel uncertainty branch for neural networks to induce the compensation bias only to relevant regions. Our method is employed into state-of-the-art segmentation frameworks and several experiments demonstrate that our proposed compensation learns inter-class relations that allow global identification of challenging ambiguities as well as the exact localization of subsequent label noise. Additionally, it enlarges robustness against label noise during training and allows target-oriented manipulation during inference. We evaluate the proposed method on %the widely used datasets Cityscapes, KITTI-STEP, ADE20k, and COCO-stuff10k.

  Complementary-label learning is a weakly supervised learning problem. We propose a consistent approach that does not rely on the uniform distribution assumption. We find that complementary-label learning can be expressed as a set of negative-unlabeled binary classification problems.

• Semi-Supervised Semantic Segmentation With Region Relevance [28.92449538610617]
  Semi-supervised semantic segmentation aims to learn from a small amount of labeled data and plenty of unlabeled ones. The most common approach is to generate pseudo-labels for unlabeled images to augment the training data. This paper proposes a Region Relevance Network (RRN) to alleviate the problem mentioned above.

  Mask proposal models have significantly improved the performance of zero-shot semantic segmentation. The use of a background' embedding during training in these methods is problematic as the resulting model tends to over-learn and assign all unseen classes as the background class instead of their correct labels. This paper proposes novel class enhancement losses to bypass the use of the background embbedding during training, and simultaneously exploit the semantic relationship between text embeddings and mask proposals by ranking the similarity scores.

  We propose a novel multi-class robust learning method for Loss Decomposition and Centroid Estimation (LDCE) Specifically, we decompose the commonly adopted loss function into a label-dependent part and a label-independent part. By defining a new form of data centroid, we transform the recovery problem of a label-dependent part to a centroid estimation problem.

• Progressive Identification of True Labels for Partial-Label Learning [112.94467491335611]
  Partial-label learning (PLL) is a typical weakly supervised learning problem, where each training instance is equipped with a set of candidate labels among which only one is the true label. Most existing methods elaborately designed as constrained optimizations that must be solved in specific manners, making their computational complexity a bottleneck for scaling up to big data. This paper proposes a novel framework of classifier with flexibility on the model and optimization algorithm.
