Visual Question Answering for a Pediatric Radiology Workflow
Overview
What this challenge is about.
Visual Question Answering for a Pediatric Radiology Workflow. Advanced challenge in research. Conducting rigorous research on real questions, earn a blockcha...
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.
