Evaluating 12 ImageNet-pretrained architectures across IN-Val, IN-V2, IN-R, IN-A, and IN-C using:
- ECE
- AURC
- selective prediction
- corruption robustness
- universal failure analysis
Benchmarked 10 dehazing architectures and identified a 15–20 dB PSNR gap between synthetic benchmarks and real dense-fog highway conditions.
Improved F1 from 0.784 → 0.866 on a 700K-post dataset using:
- XLM-R transfer learning
- BiGRU attention fusion
- multilingual representation learning
