Research Experience

Research Assistant

Machine Intelligence Lab, North South University
January 2026 – Present  ·  Dhaka, Bangladesh
  • Lead author on CLIPByte, a tokenizer-free vision–language model for multilingual open-vocabulary image captioning across six typologically diverse languages (English, Thai, Japanese, Italian, German, Vietnamese).
  • Designed cross-modal alignment between a CLIP ViT-B/32 visual encoder and a ByT5-small byte-level decoder, removing tokenizer-induced OOV bottlenecks for low-resource scripts.
  • Built the multilingual evaluation pipeline (CIDEr, METEOR, ROUGE-L, BLEU) including a Unicode-safe fix to pycocoevalcap's PTBTokenizer for non-ASCII captions, with NaN-safe averaging and persistent JSON logging.
  • Investigating tokenizer-free pretraining objectives, byte-level sequence-length efficiency, and contrastive temperature behavior at character granularity.

Undergraduate Research Assistant

Supervisor: Dr. Mohammad Abu Yousuf · North South University
January 2024 – 2025  ·  Dhaka, Bangladesh
  • Led work on multi-teacher knowledge distillation for brain-tumor classification (published, Knowledge-Based Systems, Q1, IF 7.6), targeting resource-constrained deployment with explainable-AI overlays.
  • Co-led the Bangladesh 2024 Mass Uprising sentiment study (ICCIT 2025), curating a large-scale multi-platform corpus and benchmarking classical and transformer-based NLP models on context-shifted political discourse.
  • Contributed to early-stage exploration of image reconstruction from human brain activity via cross-modal generative models (NeuroCinema-style hierarchical encoders coupled with conditional diffusion).

Selected Research Projects

NSU Chat Assistant — Retrieval-Augmented Question Answering

RAG · LLaMA-3-8B · Nomic Embed Text
2024

Built a domain-grounded RAG chatbot for university administrative queries; LLaMA-3-8B generator with Nomic-Embed-Text retrieval over a curated NSU document index.

Transformer-Based E-Commerce Sentiment Analysis

BERT fine-tuning
2024

Fine-tuned BERT for three-way sentiment classification on e-commerce reviews; analyzed error modes against classical baselines (SVM, Random Forest, AdaBoost, Gradient Boosting, KNN, Decision Tree).

ML-Based Hybrid Power Production Forecasting

Predictive modeling for renewable-energy systems
2024

Developed a predictive model for hybrid solar/wind/conventional power generation; benchmarked tree- and ensemble-based regressors for short-horizon forecasting.
