Unsupervised Fault Detection
Unsupervised fault detection aims to identify anomalies in complex systems without relying on labeled data, a crucial task for predictive maintenance and efficient operations. Current research focuses on developing robust algorithms, including those based on generative pre-training, contrastive learning, and graph convolutional networks, often incorporating techniques like moving window approaches and data augmentation to improve accuracy and handle diverse data distributions. These advancements are significantly impacting various fields, enabling more efficient monitoring of industrial processes (e.g., semiconductor manufacturing, chemical processes) and improving the reliability of critical infrastructure by facilitating early fault detection and prevention.
