Hi, I'm Mahrufa Binta Ali ✨

AI/ML Research & Applied Software Development


πŸ‘©β€πŸ’» About Me

Coding

I work on AI/ML research and applied software projects, with a focus on building, testing, and evaluating intelligent systems.

My current work explores how machine learning models learn useful representations, align different types of data, and perform in retrieval-based tasks. I am especially interested in:

  • 🧠 Multimodal learning
  • πŸ” Retrieval systems
  • πŸ“Š Model evaluation
  • 🧬 Representation learning
  • πŸ₯ Medical AI
  • πŸ› οΈ Applied AI systems

I like building projects that do not stop at:

β€œThe model trained successfully.”

I care about what the model actually learned, how it behaves, where it fails, and whether the evaluation proves meaningful progress.
