AmnioML: Amniotic Fluid Segmentation and Volume Prediction with Uncertainty Quantification

AAAI 2023technical

Accurately predicting the volume of amniotic fluid is fundamental to assessing pregnancy risks, though the task usually requires many hours of laborious work by medical experts. In this paper, we present AmnioML, a machine learning solution that leverages deep learning and conformal prediction to o…

ExactBoost: Directly Boosting the Margin in Combinatorial and Non-decomposable Metrics

AISTATS 2022poster

Many classification algorithms require the use of surrogate losses when the intended loss function is combinatorial or non-decomposable. This paper introduces a fast and exact stagewise optimization algorithm, dubbed ExactBoost, that boosts stumps to the actual loss function. By developing a novel e…
