Predictive analytics refer to algorithms that can predict when a system will fail or require intervention before this happens. These can run on the cloud or on edge processors. These can be very sophisticated depending on the complexity of the system being monitored and the type of condition that one wished to predict. There are many classes of algorithms used included those based on statistical processing and machine learning. Very often, algorithms must be trained using known data sets of normal operation as well as potential fault situations.
