The Adaptive Model Hid Its Own Drift
Fast internal updates erased the error signal before cumulative drift detectors could cross threshold.
Summary
Fast internal updates erased the error signal before cumulative drift detectors could cross threshold.
In an instrumented Adaptive Random Forest, surviving trees absorbed 98.6% of the post-drift error transient through leaf updates. A first background-tree swap represented little erased error itself but reduced external detection rates by 31 percentage points. Monitoring only the model's error stream can therefore miss the shift the model is already adapting to.
Why it matters
Fast internal updates erased the error signal before cumulative drift detectors could cross threshold.
