Practice Problems
Evidence Region Validator
Validate a model-proposed page-region citation against trusted document metadata: the revision, a zero-based page index, and a normalized rectangle of finite numbers, then return a new minimal record or the exact error of the first failed check.
AI Engineering
Handle an uncertain screenshot
Route a blurry code screenshot and a mixed PDF to suitable extraction methods, and explain the result with evidence the user can check and honest uncertainty.
Validate page-region citations
Implement a validator for page-region citations and predict its result on fixed cases. Then design extraction for a mixed PDF with a rotated scan and a table split across two pages.
Design a verifiable document and media pipeline
Design a pipeline that turns a partly scanned course pack and a lesson recording into cited study material, tracking coverage, transforms, and cross-modal conflicts, and decide what it may answer while processing is still partial.
