Abstract

While large text-to-image models are able to synthesize "novel" images, these images are necessarily a reflection of the training data. The problem of data attribution in such models -- which of the images in the training set are most responsible for the appearance of a given generated image -- is a difficult yet important one. As an initial step toward this problem, we evaluate attribution through "customization" methods, which tune an existing large-scale model toward a given exemplar object or style. Our key insight is that this allow us to efficiently create synthetic images that are computationally influenced by the exemplar by construction. With our new dataset of such exemplar-influenced images, we are able to evaluate various data attribution algorithms and different possible feature spaces. Furthermore, by training on our dataset, we can tune standard models, such as DINO, CLIP, and ViT, toward the attribution problem. Even though the procedure is tuned towards small exemplar sets, we show generalization to larger sets. Finally, by taking into account the inherent uncertainty of the problem, we can assign soft attribution scores over a set of training images.

Setup

Set up conda environment

conda env create -f environment.yaml
conda activate gen-attr

Download model weights and data

# Download precomputed features of 1M LAION images
bash feats/download_laion_feats.sh

# Download jpeg-ed 1M LAION images for visualization
bash dataset/download_dataset.sh laion_jpeg

# Download pretrained models
bash weights/download_weights.sh

Quick Start (Interactive Demo)

We estimate training data influence by learned feature similarity. This demo takes in a Stable-Diffusion-generated image as query, and output influence scores from the 1M subset of LAION images. To launch the demo, run:

streamlit run streamlit_demo.py

Dataset

We release our testset for evaluation. To download the dataset:

# Download the exemplar real images
bash dataset/download_dataset.sh exemplar

# Download the testset portion of images synthesized from Custom Diffusion
bash dataset/download_dataset.sh testset

# (Optional, can download precomputed features instead!)
# Download the uncompressed 1M LAION subset in pngs
bash dataset/download_dataset.sh laion

The dataset is structured as follows:

dataset
├── exemplar
│   ├── artchive
│   ├── bamfg
│   └── imagenet
├── synth
│   ├── artchive
│   ├── bamfg
│   └── imagenet
├── laion_subset
└── json
    ├──test_artchive.json
    ├──test_bamfg.json
    ├──...

All exemplar images are stored in dataset/exemplar, all synthesized images are stored in dataset/synth, and 1M laion images in pngs are stored in dataset/laion_subset. The JSON files in dataset/json specify the train/val/test splits, including different test cases, and serve as ground truth labels. Each entry inside a JSON file is a unique fine-tuned model. An entry also records the exemplar image(s) used for finetuning and the synthesized images generated by the model. We have four test cases: test_artchive.json, test_bamfg.json, test_observed_imagenet.json, and test_unobserved_imagenet.json.

(We will release the train and validation set in the near future!)

Evaluation

After the testset, precomputed LAION features, and pretrained weights are downloaded, we can precompute the features from the testset by running extract_feat.py, and then evaluate the performance by running eval.py. Below are the bash scripts that runs the evaluation in batches:

# precompute all features from the testset
bash scripts/preprocess_feats.sh

# run evaluation in batches
bash scripts/run_eval.sh

The metrics are stored in .pkl files in results. Currently, the script runs each command sequentially. Please feel free to modify it to run the commands in parallel. The following command will parse the .pkl files into tables stored as .csv files:

python results_to_csv.py

12/18/2023 Update To download models only trained on object-centric or style-centric models, run bash weights/download_style_object_ablation.sh
