NeckSense: A Multi-Sensor Necklace for Detecting Eating Activities in Free-Living Conditions

no code implementations17 Nov 2019 Shibo Zhang, Yuqi Zhao, Dzung Tri Nguyen, Runsheng Xu, Sougata Sen, Josiah Hester, Nabil Alshurafa

Moreover, our system can achieve a F1-score of 77. 1% for episodes even in an all-day-around free-living setting.

Visualization of Multi-Objective Switched Reluctance Machine Optimization at Multiple Operating Conditions with t-SNE

no code implementations4 Nov 2019 Shen Zhang, Shibo Zhang, Sufei Li, Liang Du, Thomas G. Habetler

However, the number of objectives that would need to be optimized would significantly increase with the number of operating points considered in the optimization, thus posting a potential problem in regards to the visualization techniques currently in use, such as in the scatter plots of Pareto fronts, the parallel coordinates, and in the principal component analysis (PCA), inhibiting their ability to provide machine designers with intuitive and informative visualizations of all of the design candidates and their ability to pick a few for further fine-tuning with performance verification.

Machine Learning and Deep Learning Algorithms for Bearing Fault Diagnostics -- A Comprehensive Review

no code implementations24 Jan 2019 Shen Zhang, Shibo Zhang, Bingnan Wang, Thomas G. Habetler

In this paper, we first provide a brief review of conventional ML methods, before taking a deep dive into the state-of-the-art DL algorithms for bearing fault applications.
