A Practical GPU-Accelerated Implementation of Orthogonal Matching Pursuit
Ariel Lubonja, Sebastian Kazmarek Praesius, Trac Duy Tran
Finding the sparsest solution to the underdetermined system , given a tolerance, is known to be NP-hard. Many approximate solutions to this problem exist, a…
Vectorized Adaptive Histograms for Sparse Oblique Forests
Ariel Lubonja, Jungsang Yoon, Haoyin Xu +6
Classification using sparse oblique random forests provides guarantees on uncertainty and confidence while controlling for specific error types. However, they use more data and mor…
Auditing Significance, Metric Choice, and Demographic Fairness in Medical AI Challenges
Ariel Lubonja, Pedro R. A. S. Bassi, Wenxuan Li +4
Open challenges have become the de facto standard for comparative ranking of medical AI methods. Despite their importance, medical AI leaderboards exhibit three persistent limitati…
Analysis of inertial-range intermittency in forward and inverse cascade regions in isotropic turbulence
H. Yao, M. Schnaubelt, A. Lubonja +10
In order to test the hypothesis that inverse cascade regions in turbulent flows might exhibit more Gaussian noise-like and less intermittent small-scale statistics compared to the…
