Jun 08, 2017 · From top to bottom: original time series, seasonal, trend and residue parts retrieved using STL decomposition. As the name states, it is suitable for seasonal time series, which is the most popular case. If you analyze deviation of residue and introduce some threshold for it, you’ll get an anomaly detection algorithm.

Automated Optical Inspection (AOI), which is an automated visual inspection of a Printed Circuit Board (PCB), provides 100% visible component and solder-joint inspection. This testing method has been in use in PCB manufacturing for almost two decades. It plays a critical role in ensuring that there are no random faults in the assembly. Defending Machine Learning models involves certifying and verifying model robustness and model hardening with approaches such as pre-processing inputs, augmenting training data with adversarial samples, and leveraging runtime detection methods to flag any inputs that might have been modified by an adversary.

Fault detection techniques. For any PLC controlled plant, by far the greater percentage of the faults are likelly to be with sensors, actuators, and wiring rather than with PLC itself. The faults within the PLC most are likely to be in the input/output channells or power supply than in the CPU.
With an image classification model, you generate image features (through traditional or deep learning methods) of the full image. These features are aggregates of the image. With object detection, you do this on a more fine-grained, granular, regional level of the image.
