TL;DR: In this paper, the effect of truthing when aggregating labels from multiple experts is investigated. But the authors find that specific choices can have severe impact on the data distribution where it may be possible to achieve superior performance on one sample distribution but not on another.

Learning from Partially Overlapping Labels: Image Segmentation under Annotation Shift
TL;DR: In this article, the authors investigate and propose several strategies for learning from partially overlapping labels in the context of abdominal organ segmentation, and find that combining a semi-supervised approach with an adaptive cross entropy loss can successfully exploit heterogeneously annotated data and substantially improve segmentation accuracy compared to baseline and alternative approaches.

High Fidelity Image Counterfactuals with Probabilistic Causal Models
TL;DR: In this paper , the authors present a general causal generative modeling framework for accurate estimation of high fidelity image counterfactuals with deep structural causal models, which leverage ideas from causal mediation analysis and advances in generative modelling to design new deep causal mechanisms for structured variables in causal models.
