The Brief

What you'll do, and what you'll demonstrate.

Build a VQA prototype on pediatric chest X-rays that hits per-category sensitivity ≥0.80 at specificity ≥0.85 with calibrated probabilities and per-question attention maps.

This is not a research exercise. It is the work a researcher does to produce findings that withstand scrutiny. That distinction matters to every hiring manager who has seen candidates summarize papers and none who have produced original findings under expert review.

When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."

Earning criteria — what you'll demonstrate

  • Adapt an open vision-language model to a clinical-style visual reasoning task with LoRA
  • Measure calibration of a yes/no medical classifier with reliability diagrams and Expected Calibration Error
  • Generate and qualitatively assess attention/saliency maps as explanation surfaces
  • Communicate model limitations and dataset bias honestly to a non-ML clinical audience

Careers

Career paths this challenge builds toward

Completing this challenge demonstrates skills that transfer directly to these roles:

ML Researcher

Fine-tuning an open vision-language model on a domain task and writing a careful, calibrated evaluation is the foundational deliverable expected of a junior ML researcher in healthtech or any domain-specific AI team.

This challenge sharpens

  • vision-language-models
  • lora-finetuning
  • calibration

Research Scientist

Reporting per-category sensitivity/specificity with reliability diagrams and explicit limitations mirrors the rigor expected in a research-scientist's first publication-ready evaluation.

This challenge sharpens

  • evaluation
  • calibration
  • visual-question-answering

Applied AI Scientist

Translating a research-grade VQA evaluation into a board-ready advisory deck with honest limitations is daily work for applied AI scientists in regulated industries.

This challenge sharpens

  • evaluation
  • visual-question-answering
  • pytorch
