Checklist ROAI 2026 Selection Camp – GPU Practical Round · Task 3
Fake it until you make it
Detect Stable Diffusion v1.5 images among arbitrary real photographs when the training set contains only real images of dogs.
The task
The training set consists exclusively of real photographs of dogs; no generated images are provided. The hidden test set contains random real images from the internet and images generated with Stable Diffusion v1.5, not necessarily of dogs.
The starter kit shows how to generate images with Stable Diffusion v1.5 and includes offline diffusers documentation and examples. The contestant predicts 0 (real) or 1 (AI-generated) for each test image.
Abridged by SOTA from the official materials. The official statement has the exact rules, and it wins wherever this summary differs.
At a glance
- You get
- Training images of real dogs; unlabelled test images; starter kit with a Stable Diffusion v1.5 generation example and offline diffusers documentation.
- You submit
- CSV with subtaskID (always 1), datapointID (test image id) and answer (0 or 1).
- Scoring
- Weighted F1: below 0.54 gives 5 points, 0.54–0.94 is scaled linearly from 5 to 100, 0.94 or above gives 100.
