Evaluating the Alignment Between GeoAI Explanations and Domain Knowledge in Satellite-Based Flood Mapping
Summary
This study introduces the ADAGE (Alignment between Domain Knowledge And GeoAI Explanation Evaluation) framework, designed to systematically evaluate the alignment between deep learning model explanations and established remote sensing domain knowledge in satellite-based flood mapping. The framework addresses the opacity of deep learning models by employing a Channel-Group SHAP (SHapley Additive exPlanations) method. This method estimates the contributions of grouped input channels to pixel-level predictions, aligning the explanatory level with domain knowledge. Experiments on two satellite-based flood mapping tasks, including multimodal post-flood water extent mapping and SAR-based open/urban area flood mapping, demonstrate ADAGE's ability to quantitatively assess alignment scores. It also helps domain experts identify misaligned explanations, which could indicate novel pattern discovery or spurious correlations, thereby enhancing the trustworthiness and applicability of GeoAI models in operational workflows.
Key takeaway
For Computer Vision Engineers deploying deep learning models for satellite-based flood mapping, you should integrate the ADAGE framework into your model selection process. This allows you to evaluate not only predictive accuracy (IoU) but also the alignment of model explanations with established remote sensing domain knowledge. Prioritize models demonstrating both high performance and strong alignment to ensure trustworthiness and avoid deploying models that might rely on spurious correlations, requiring further investigation if misalignment is detected.
Key insights
The ADAGE framework quantifies alignment between GeoAI model explanations and remote sensing domain knowledge for flood mapping.
Principles
- Model explanations should align with established domain knowledge.
- Channel grouping enables comparable explanation levels.
- High alignment scores indicate trustworthy model reasoning.
Method
The ADAGE framework uses Channel-Group SHAP to estimate grouped input channel contributions to pixel-level predictions. It then calculates an mAP@k alignment score against domain knowledge-derived reference explanations.
In practice
- Use ADAGE to evaluate GeoAI model trustworthiness.
- Identify misaligned explanations for further investigation.
- Select models with high IoU and high alignment scores.
