Supervised Health Stage Prediction Using Convolutional Neural Networks for Bearing Wear

Sungho Suh, Joel Jang, Seungjae Won, Mayank Shekhar Jha, Yong Oh Lee
2020 Sensors  
In this paper, we propose a novel data-driven health division method based on convolutional neural networks using a graphical representation of time series data, called a nested scatter plot.  ...  Current methods of fault detection suffer from the lack of efficient feature extraction method, the need for designating a threshold producing minimal false alarm rates, and the need for expert domain  ...  Supervised Health Stage Prediction Image Transformation of Vibration Signals NSP is a data wrangling method that transforms correlated time series data into an image for multi-variate correlation analysis  ...

Generative Oversampling Method for Imbalanced Data on Bearing Fault Detection and Diagnosis

Sungho Suh, Haebom Lee, Jun Jo, Paul Lukowicz, Yong Lee
2019 Applied Sciences  
In this study, we developed a novel data-driven fault detection and diagnosis (FDD) method for bearing faults in induction motors where the fault condition data are imbalanced.  ...  First, we propose a bearing fault detector based on convolutional neural networks (CNN), in which the vibration signals from a test bench are used as inputs after an image transformation procedure.  ...  Acknowledgments: We thank Andrea Bubert and Stefan Quabeck in ISEA of RWTH Aachen University for discussion on data collection and synthetic fault data generation.  ...

Data-driven prototyping in information visualization

Michael Oppermann
2021
We provide a detailed characterization of non-contiguous time series slices and propose TimeElide, a domain-agnostic visual analysis tool and design space.  ...  The findings from the Ocupado study highlight the need for analyzing data concerning time periods of interest that are known in advance rather than determined on the fly.  ...  For example, while looking at a report, a CBR system might also recommend the related report for comparison and it is not relevant whether the workbook contains a scatter plot or a bar chart.  ...
