docs: fill in dataset card sections (bias, limitations, curation rationale)

#6
Commit history is no longer available for this pull request.

Fills in the dataset card sections that were previously marked as [More Information Needed].

Changes:

  • Curation Rationale: describes why the 101 categories were chosen and the benchmark's design goals
  • Source Data: documents that images came from Foodspotting.com and describes the data collection process
  • Annotations: clarifies the difference between cleaned test labels and noisy training labels
  • Personal and Sensitive Information: notes restaurant-setting photography context
  • Social Impact: describes deployment contexts (dietary apps, nutrition tracking, recommendation systems) and global coverage limitations
  • Discussion of Biases: documents category selection bias (Western restaurant cuisine skew), dietary category imbalance (~12-15% plant-based classes), label noise in training split, and photography style bias
  • Other Known Limitations: covers noisy training labels, test set statistical power, missing nutritional metadata, and points to extended benchmarks with broader international coverage
  • Dataset Curators: identifies ETH Zurich authors (Bossard, Guillaumin, Van Gool, ECCV 2014)

All information is sourced from the original paper and the dataset homepage.
