Research area
Environmental data quality
The effect of missingness, observational uncertainty, aggregation and measurement inconsistencies on learned models and the decisions built on them.
Rationale
The research problem.
Sensor and reference data are part of the model-selection system, not neutral inputs. This line examines how missingness, substitution, spatial mismatch and measurement degradation propagate into evaluation results and deployment recommendations.
Research questions
Questions that guide this area.
- 01
Which data-quality failures are credible for a particular deployment?
- 02
How sensitive are reported conclusions to aggregation and reference choice?
- 03
Can provenance and perturbation assumptions be made auditable?
