Automated Kernel Search for Gaussian Processes on Data Streams

2021 · 2021 IEEE International Conference on Big Data (Big Data)

Gaussian Processes offer non-parametric, probabilistic models that can be used in numerous fields of data analysis. One major drawback is their lack of adjustability in case of drifting and evolving streaming data, where inherent kernels …

Fault Detection in Transmission Production Lines Based on Imbalanced Multivariate Time Series

2024

Traditional Noise, Vibration, and Harshness (NVH) testing is costly and complex, requiring manual limit setting by skilled NVH engineers. Additionally, production line data is mostly imbalanced, leading to bias toward the majority class in classification …
