Predicting rare machine failures with extreme class imbalance
A 100K-sample dataset with only 56 failure cases presents a classic imbalance problem for predictive maintenance models. We examine the technical approaches that work when positive examples are 0.056% of your data.

A practitioner working on predictive maintenance for industrial equipment faces a common problem: a dataset of 100,000 timestamped observations where only 56 samples represent actual machine failures. The class imbalance ratio is approximately 1,785 to 1 (56 failures versus 99,944 normal operating s...
