On a Method to Measure Supervised Multiclass Model’s Interpretability: Application to Degradation Diagnosis (Short Paper)

🤖 Plain-English Summary

In an industrial maintenance context, degradation diagnosis is the problem of determining the current level of degradation of operating machines based on measurements. The proposed method requires that the decision maker sets up some high level parameters in order to measure the interpretability of the models and then can decide whether the obtained models are satisfactory or not.

🔑 Key Findings

• With the emergence of Machine Learning techniques, such a problem can now be solved by training a degradation model offline and by using it online.
• While such models are more and more accurate and performant, they are often black-box and their decisions are therefore not interpretable for human maintenance operators.
• On the contrary, interpretable ML models are able to provide explanations for the model’s decisions and consequently improves the confidence of the human operator about the maintenance decision based on these models.
