Where and Why TerraMind's Optical-to-SAR Generation Fails

Explainable Machine Learning 2025/2026, University of Warsaw

Findings

• TM-003Optical-to-SAR generation errors cluster spatially, but only five regions survive FDR control
• TM-004Surface composition, not the acquisition time gap, correlates with optical-to-SAR reconstruction error
• TM-005Flooded vegetation gives the lowest reconstruction error of any land-cover class, not the highest
