Muhammad Dyen Asif

Undergraduate researcher in trustworthy machine learning, computer vision and edge AI. BS Computer Science, FAST-NUCES Islamabad.

I work on the problem of models that are confidently wrong, and on the systems that have to survive that: uncertainty quantification, calibration, out-of-distribution behaviour, and human-in-the-loop escalation when a prediction should not be trusted.

Risk-Aware Active Learning for Skin Lesion Classification · manuscript under peer review, 2026 L. Noor, M. D. Asif, H. Ramzan, A. Atiq, M. A. Saeed, A. Jamil, A. Din

A dual-metric human-in-the-loop escalation policy for dermoscopy: a case is routed to a clinician when either model uncertainty or a dedicated clinical-risk head crosses a per-round calibrated threshold. This targets the failure standard active learning cannot see, where a model is confidently wrong about a melanoma and auto-accepts it. We prove the escalation set is a superset of the uncertainty-only set, so unsafe auto-acceptance cannot increase.

Across 24 experiments on HAM10000: 43% fewer unsafe auto-accepts in 12 of 12 matched configurations, at 9.1% more oracle labels (Holm-corrected p = 0.003), with no significant change in F1-macro (p = 0.305). Validated out-of-distribution on 14,885 ISIC-2019 images with HAM10000 duplicates removed: 83.3% accuracy win rate, 75.0% melanoma-safety win rate. → RiskAware-ActiveLearning

Hallucination-Free Retrieval-Augmented Generation · undergraduate research assistant, FAST-NUCES

An agentic RAG question-answering system for Classical Arabic: GATE Arabic embeddings fine-tuned with Matryoshka loss, an HNSW index over 12,472 provenance-tagged passages, and a bounded retrieve → sufficiency-check → rewrite loop with per-step citation validation. I build the evaluation framework, including a knowledge-graph guardrail that extracts subject-relation-object triples from source and answer to reject unsupported claims.
