This work presents SuperClass, a super simple classification method that performs vision-language pre-training. Our method does not require a text encoder to be pre-trained on image-text data. Instead, it utilizes tokenized raw text as supervised classification labels, without the need for additional text filtering or selection.

News

• 2024-11-06: Paper & code are all released.
• 2024-10-02: SuperClass is accepted by NeurIPS 2024.

Usage

Prepraration

git clone https://github.com/x-cls/superclass
cd superclass
pip install -r requirements.txt

Download the datasets Datacomp-1B and ImageNet-1K. You can also use other image-text pair datasets for training.

Modify the DATA_PATH and VAL_DATA_PATH in training script train.sh and train_combo.sh to your local paths to Datacomp-1B and ImageNet-1K.

CLIP Training & Superclass Training

To start CLIP training and superclass training, use the following command:

bash train.sh <config_path> opencls

This script will navigate to the opencls directory and execute the training.

If you want to include the LiT training phase, use the following command:

bash train_combo.sh <cls_config_path> <lit_config_path> opencls

CLS training config are here opencls/configs/cls_schedule

For example:

bash train.sh configs/cls_schedule/cls_vit_b16_s1.28B_bs16k.yaml opencls
