#Point-Cloud-Native L-Band Augmentation of SWOT KaRIn: Recovering Canopy-Shadowed Dark Water with NISAR [DOI]

W. Shoaib, B. Ismail, M. Salik

IEEE Geoscience and Remote Sensing Letters, 2026

First combined use of NISAR L-band SAR and SWOT pixel clouds on real co-observed scenes. +11.3 pp dark-water recall on Congo, +17.9 pp on Amazon (disjoint 95% bootstrap CIs).

#Semantic-Conditioned Spectral Fusion for Label-Efficient Multispectral Adaptation of Frozen Remote-Sensing VLMs [DOI]

B. Ismail, W. Shoaib

IEEE Geoscience and Remote Sensing Letters, 2026. (Under Review)

~0.1M parameter module adapting frozen RGB VLMs to multispectral imagery via FiLM-conditioned spectral fusion. +4.6% accuracy on EuroSAT-MS.

#Why Production AI Fails on Day 90 — and What Evaluator-First Architecture Fixes [PDF]

W. Shoaib

Whitepaper, 2026

Proposes an evaluator-first architecture where evaluation agents are built before generation agents, enabling production AI systems that self-correct and improve post-deployment.

Open Source Contributions

Ragas Framework (PR #3008)

Fixed three metric integrity bugs that could silently corrupt evaluation scores in production. 24 deterministic regression tests.

  • NaN masking — np.nanmean hiding 90% failure rates as perfect scores
  • Prompt injection — unsanitized context reaching judge prompts
  • JSON extraction — preliminary verdicts overriding final ones
