The JNU dataset focuses on roller bearing faults, emphasizing classification challenges due to various speed conditions and the presence of multiple fault types, necessitating advanced computational techniques.
Each sample in the JNU dataset was recorded at a 50KHz sampling rate for 20 seconds, facilitating detailed analysis of bearing performance under artificial defects created in a controlled setting.
The classification task is structured into ten classes, including three fault types at three different rotation speeds, plus a healthy class, making it a complex dataset for testing algorithms.
With limited data volume, the JNU dataset required an overlapping strategy for signal segments, showcasing the necessity of meticulous data preparation in machine learning and classification tasks.
