Stages of the proposed methodology.
| Step | Process | Purpose | Output |
| 1 | Sensor measurement collection (sampled or batch) | ā | Collate data for analysis | 2 | VBGMM | Preprocess data to remove transient measurements | Measurements only of steady state operation | 3 | Statistical analysis | Extraction of important features within the data | Features for identifying emerging faults | 4 | GMMOC | Novelty detection of emerging faults | Early warning of emerging or imminent fault conditions |
