Trust-SSL adds per-sample confidence weights to contrastive loss, improving aerial image representation learning under haze, blur, and occlusion.

  • Standard SSL enforces alignment between clean and degraded views, risking spurious latent structure.
  • Trust-SSL assigns per-sample, per-corruption-factor weights to the alignment objective.
  • Additive-residual formulation with stop-gradient outperforms multiplicative gating on backbone quality.
  • Achieves 90.20% linear-probe accuracy on EuroSAT, AID, NWPU-RESISC45 benchmarks.
  • Gains +19.9 points on severe haze corruption versus SimCLR baseline.
  • Evidential variant using Dempster-Shafer fusion provides interpretable conflict and ignorance signals.
  • Cross-domain stress test shows +1 to +3 point improvements in Mahalanobis AUROC.

Frequently asked

  • Multiplicative gating can suppress gradient flow through the backbone when trust weights are low, degrading feature learning. Additive-residual formulation preserves the base contrastive signal while adding a confidence-scaled correction term, allowing the backbone to learn from both clean and degraded samples without bottlenecking gradients. Experiments show this design yields higher linear-probe accuracy and robustness.
