Systems fail, they cascade onto the next and a next. Chaos! The sheer magnitude of combinations that could go wrong and impact each other screams for the use of AI in predicting failure. Chaos prevented.
Teaching an AI system to recognise faults no easy task. Domain experts are needed to show what is right and what is wrong. Data needs to be collected and interpreted. Faults will be made but eventually AI can recognise faults. At first it will tell you a failure is there after it occurred. You could have done that as well. A few lessons more and AI is taught to tell you a failure is occurring right now. Still too late but better. Eventually the AI will tell you something will go wrong in the near future.
AI needs to people to teach, data to work with and time to get better. A failure occurred because I told you so!
