Rule extraction from biased random forest and fuzzy support vector machine for early diagnosis of diabetes

open access: yesScientific Reports, 2022
Due to concealed initial symptoms, many diabetic patients are not diagnosed in time, which delays treatment. Machine learning methods have been applied to increase the diagnosis rate, but most of them are black boxes lacking interpretability.

Performance Evaluation of Machine Learning Methods for Anomaly Detection in CubeSat Solar Panels

open access: yesApplied Sciences, 2022
CubeSat requirements in terms of size, weight, and power restrict the possibility of having redundant systems. Consequently, telemetry data are the primary way to verify the status of the satellites in operation.

Momentum-resolved electronic structure of LaTiO2N photocatalysts by resonant Soft-X-ray ARPES

open access: yesCommunications Materials, 2023
LaTiO2N is a promising photocatalyst for light-driven water splitting. Here, ARPES is used to study the momentum-resolved electronic structure of the sub-surface region of LaTiO2N and monitor its evolution during the oxygen evolution reaction.
