MONET (Medical cONcept rETriever)

MONET is an image-text foundation model trained on 105,550 dermatological images paired with natural language descriptions from a large collection of medical literature. MONET can accurately annotate concepts across dermatology images as verified by board-certified dermatologists, competitively with supervised models built on previously concept-annotated dermatology datasets of clinical images. MONET enables AI transparency across the entire AI system development pipeline from building inherently interpretable models to dataset and model auditing.

Getting started

Install

To install the required packages, run the following bash commands:

# clone project
git clone https://github.com/suinleelab/MONET
cd MONET

# [OPTIONAL] create conda environment
conda create -n MONET python=3.9.15
conda activate MONET

# install PyTorch according to instructions at https://pytorch.org/get-started/ v.1.13.0 was used during development.
# example: conda install pytorch==1.13.0 torchvision==0.14.0 pytorch-cuda=11.7 -c pytorch -c nvidia

# install other required python packages
pip install -r requirements.txt
pip install git+https://github.com/openai/CLIP.git

Initialize model

Using original openai CLIP implementation

import clip

def get_transform(n_px):
    def convert_image_to_rgb(image):
        return image.convert("RGB")
    return T.Compose(
        [
            T.Resize(n_px, interpolation=T.InterpolationMode.BICUBIC),
            T.CenterCrop(n_px),
            convert_image_to_rgb,
            T.ToTensor(),
            T.Normalize((0.485, 0.456, 0.406), (0.229, 0.224, 0.225)),        
        ]
    )

model, preprocess = clip.load("ViT-L/14", device="cuda:0", jit=False), get_transform(n_px=224)
model.load_state_dict(torch.hub.load_state_dict_from_url("https://aimslab.cs.washington.edu/MONET/weight_clip.pt"))
model.eval()

Using huggingface CLIP implementation

from transformers import AutoProcessor, AutoModelForZeroShotImageClassification

processor_hf = AutoProcessor.from_pretrained("chanwkim/monet")
model_hf = AutoModelForZeroShotImageClassification.from_pretrained("chanwkim/monet")
model_hf.to("cuda:0")
model_hf.eval()

Usage

We provide jupyter notebooks to demonstrate how to use MONET for automatic concept annotation and various transparency tasks such as data auditing, model auditing, and inherently interpretable model building.

• Automatic concept annotation: tutorial/automatic_concept_annotation.ipynb
• Data auditing: tutorial/data_auditing.ipynb
• Model auditing: tutorial/model_auditing.ipynb
• Inherently interpretable model building: tutorial/inherently_interpretable_model_building.ipynb

MONET Training data

For code to download and preprocess the training data, please refer to the following scripts:
