This is a smarter way to teach AI to predict when critical machines will wear out, even when most of the data shows them running normally and only a few cases show them actually failing. It ‘rebiases’ the learning so the model pays proper attention to the rare but important late-stage degradation, not just the easy, early-stage data.
Traditional predictive maintenance models struggle when degradation data is imbalanced: there is a lot of data when machines are healthy and very little data near failure. This leads to poor prediction of remaining useful life and late-stage degradation, which is exactly where accurate prediction matters most for safety and cost. The proposed time-balanced MSE loss addresses this by reweighting errors across the degradation timeline, improving prediction quality for rare but critical late-life conditions.
If adopted in production, the moat comes from proprietary historical degradation datasets (sensor histories, test-stand runs, flight logs) and from integration of the loss function into a broader predictive maintenance pipeline tuned for specific platforms or fleets.

Needing high-quality, long-horizon degradation trajectories with labeled failure/end-of-life points to train and validate the time-balanced loss at scale.
Early Adopters
The core differentiation is a custom time-balanced mean squared error loss that explicitly compensates for temporal imbalance in degradation data, improving late-stage prediction performance compared with standard losses that are dominated by abundant early-life samples.
