# Dayal, Garg and Sen introduce image attribution across Stable Diffusion fine-tunes

[Canonical reading](https://escapemeridian.com/readings/dayal-garg-and-sen-introduce-image-attribution-across-stable-0bed55a0)

Ashutosh Dayal, Mallika Garg and Debashis Sen introduce IntrAA-SD, a task for attributing an image to a fine-tuned model when candidate models share the same architectural backbone. They describe it as addressing a gap in image source attribution: existing datasets and systems mostly target architectural signatures, while fine-tunes such as Juggernaut XL and RealVis XL differ through fine-tuning of SDXL. The authors provide a benchmark dataset of 140K generated images, with in-domain and out-of-distribution prompts, and a baseline method. That method uses a style-conditioned Mixture-of-Experts network, a frozen CLIP backbone, and a high-resolution LoRA-adapted DINOv2 network. The paper says it evaluates attribution accuracy on its dataset and reports ablation studies. The work treats attribution among models with a shared architecture as a distinct research task, rather than assuming an image’s source can be identified from architectural differences. Its practical significance depends on how well the baseline performs beyond the dataset and settings described; the abstract gives no accuracy results. The authors say code and the dataset are available.

### passed — 2026-11-10T02:48:16.560Z — anthropic/claude-opus-5.5

Publication: 813776ea-09a3-4747-85e1-2fd3e65fa30f

attribution — pass: The reading correctly credits Ashutosh Dayal, Mallika Garg and Debashis Sen. The task, dataset and baseline are framed as the authors' claims rather than as established facts.

> Authors:Ashutosh Dayal, Mallika Garg, Debashis Sen

summary — pass: The title, summary and question faithfully state what the paper introduces: IntrAA-SD, a 140K-image SDXL fine-tune dataset, and a baseline. It explains the gap the authors claim, which is that prior work targets architectural signatures. It also notes that the abstract reports no accuracy figures. Technical terms are kept exactly and can be explained through tooltips. The question follows directly from the missing results.

> Most existing datasets and systems related to image source attribution are targeted towards the detection of architectural signatures of the source models.

date — pass: The originalPublished date of 2026-11-04 matches the arXiv v1 submission date. It is not the later feed date of 2026-11-05.

> \[Submitted on 4 Nov 2026\]

support — pass: Each claim is directly supported by the abstract. The interpretive sentence about treating shared-architecture attribution as a distinct task restates the authors' framing. The stated limitations, including that no accuracy results are given, are accurate and do not overstate performance. The reading invents no benefits, costs or forecasts.

> Our baseline intra-architecture source attribution method is evaluated in terms of attribution accuracy on our dataset, and ablation studies are also performed.

media — pass: The selected media is the verified direct arXiv abstract page for this paper. That is the most direct way to reach the source.
