CelebCaption

CelebCaption is a benchmark dataset for identity-sensitive unlearning in image captioning.
It contains 15 000 photographs of 150 public figures (100 images each).
Every image is paired with four aligned captions that vary along two axes:

Axis	Variant A	Variant B
Specificity	Detailed	Summary
Identity	Named	Anonymous

These matched caption sets let researchers isolate:

• Specificity Reduction – do captions lose fine-grained details for forgotten images?
• Identity Removal – are all name cues eliminated without hallucination?
• Performance Preservation – are captions for retained images still fluent and accurate?

Caption file format (captions/<person>.jsonl)

We provide the captions in .jsonl files.

The full, unsplit captions are provided in Captions_full directory, and train(retain+forget) and test split we used in our experiments are provided in Captions_split directory.

Each line is a single JSON object that links one image to its four caption variants:

{
  "image_file": "1.jpg",
  "detailed_with_name": "Abel Tesfaye is pictured wearing a white shirt ...",
  "detailed_no_name":   "A man is pictured wearing a white shirt ...",
  "summary_with_name":  "Abel Tesfaye with dreadlocks and beard ...",
  "summary_no_name":    "A man with dreadlocks and beard ..."
}

• Caption corpus: 60,000 sentences, 13 708 unique tokens
• Average image resolution: ~1.22 MP (median 1.07 MP)
