Using Ensemble Learning Techniques To Solve The Blind Drift Calibration Problem, Devin Scott Drake
Using Ensemble Learning Techniques To Solve The Blind Drift Calibration Problem, Devin Scott Drake
Computer Science Theses & Dissertations
Large sets of sensors deployed in nearly every practical environment are prone to drifting out of calibration. This drift can be sensor-based, with one or several sensors falling out of calibration, or system-wide, with changes to the physical system causing sensor-reading issues. Recalibrating sensors in either case can be both time and cost prohibitive. Ideally, some technique could be employed between the sensors and the final reading that recovers the drift-free sensor readings. This paper covers the employment of two ensemble learning techniques — stacking and bootstrap aggregation (or bagging) — to recover drift-free sensor readings from a suite of …
