Paderborn Dataset Processed for Domain Adaptation Scenarios

The dataset contains sensor readings of bearing machines under 4 different operating conditions, with each having 3 different classes, i.e., healthy, inner-bearing damage, and outer-bearing damage. Each operating condition refers to different operating parameters, including rotational speed, load torque, and radial force [. In our experiments, each operating condition is considered as one domain. Eventually, we can perform 12 cross-condition scenarios for domain adaptation. To construct the data samples for each domain, we adopted a sliding window to segment the data into small segments. We set the window size of 5120 and shifting size of 4096
