Introduction

This is model fit and inference code for CLIP aesthetic regressions trained on Simulacra Aesthetic Captions. These remarkably simple models emulate human aesthetic judgment. They can be used in tasks such as dataset filtering to remove obviously poor quality images from the corpus before training. The following grids, one sorted by John David Pressman and one sorted by the machine give some idea of the models capabilities:

Installation

Git clone this repository:

git clone https://github.com/crowsonkb/simulacra-aesthetic-models.git

Install pytorch if you don't already have it:

pip3 install torch==1.10.1+cu113 torchvision==0.11.2+cu113 torchaudio==0.10.1+cu113 -f https://download.pytorch.org/whl/cu113/torch_stable.html

Then pip install our other dependencies:

pip3 install tqdm pillow torchvision sklearn numpy

If you don't already have it installed, you'll need to install CLIP:

git clone https://github.com/openai/CLIP.git
cd CLIP
pip3 install .
cd ..

Usage

The models are largely meant to be used as a library, i.e. you'll need to write specific code for your use case. But to get you started we've provided a sample script rank_images.py which finds all the .jpg or .png images in a directory tree and ranks the top N (default 50) with the aesthetic model:
