Empirical investigation of multi-source cross-validation in clinical machine learning

no code implementations22 Mar 2024 Tuija Leinonen, David Wong, Ali Wahab, Ramesh Nadarajah, Matti Kaisti, Antti Airola

However, such estimates tend to be highly overoptimistic when compared to accuracy obtained from deploying models to sources not represented in the dataset, such as a new hospital.

Machine Learning Prediction of COVID-19 Severity Levels From Salivaomics Data

no code implementations15 Jul 2022 Aaron Wang, Feng Li, Samantha Chiang, Jennifer Fulcher, Otto Yang, David Wong, Fang Wei

The clinical spectrum of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the strain of coronavirus that caused the COVID-19 pandemic, is broad, extending from asymptomatic infection to severe immunopulmonary reactions that, if not categorized properly, may be life-threatening.

Characterization of Multiple 3D LiDARs for Localization and Mapping using Normal Distributions Transform

no code implementations3 Apr 2020 Alexander Carballo, Abraham Monrroy, David Wong, Patiphon Narksri, Jacob Lambert, Yuki Kitsukawa, Eijiro Takeuchi, Shinpei Kato, Kazuya Takeda

In this work, we present a detailed comparison of ten different 3D LiDAR sensors, covering a range of manufacturers, models, and laser configurations, for the tasks of mapping and vehicle localization, using as common reference the Normal Distributions Transform (NDT) algorithm implemented in the self-driving open source platform Autoware.
