Manual
Expensive
Today’s analytics process requires a lot of manual efforts
Outdated
Models require frequent retraining andold data is useless
High CAPEX and non-scalable tool-based approach
14. Predictive Maintenance Industrial Assets
Physical inputs: vibration, temperature and pressure...
Used supervised off-line trained models
What is normal for a machine is environment-dependent
Machines are continuously evolving
15. Can we provide an continuous
behavior learning system?
Can we monitor the real-time
behavior against the repository?
Can we use behavior monitoring
as an input for maintenance
procedures?

20. The production goal of this system is to
maintain the gas concentrations.
The capacity is determined by the main
compressor and the water pump flow.
Fault aboutMay. Maintenance
intervention.
Continued to operate the machine for
months until production loss was too high.
30. Concluding remarks
1. IoT is about everything becoming a web business.
Flexible and fast business model innovation.
2. Analytics complexity will not stop growing. Adaptive
learning is needed for IoT.
3. IoT data capture and quality will an issue and we need
resilient ML approach.
