Width should grow 2.8× faster than depth in transformers, validated across 30 architectures up to 7B parameters. Past a critical depth, adding layers actively hurts, even though parameter count increases.

Statistics taught me to ask the right questions. Machine learning gave me sharper tools. My work connects both: building AI systems efficient enough for edge hardware, rigorous enough for public health decisions, and honest enough about their own failure modes.
Based in Bangladesh, I'm currently working in the Data Science Research Lab of our Statistics Department at the University of Rajshahi, under the supervision of Prof. Dr. M. Rezaul Karim. Now, I'm seeking a PhD position in artificial intelligence, machine learning, or related fields.

The revised preprint maps all 17 SDGs across 114 countries and finds 84 supported directed linkages after false-discovery control. No single goal behaves as a stable universal accelerator, so portfolio policy should track time-lagged, evidence-backed linkages instead of rankings alone.

239× fewer parameters than GraphCast at near-identical accuracy. Principled multi-objective NAS can find truly deployable models, and transfer learning adds ~5% accuracy gains when historical data is scarce.

Multi-objective NAS for efficiency under real deployment constraints
A research project on multi-objective neural architecture search (NAS) that explicitly targets efficiency (parameters/energy) while keeping forecasting accuracy competitive.
Evidence that width should grow faster than depth for transformers
A research project studying architecture-conditioned scaling laws and identifying a critical-depth regime where adding layers can hurt performance.
