Model Card for CLIP ViT-B/32 xlm roberta base - LAION-5B

Table of Contents

Model Details

Model Description

A CLIP ViT-B/32 xlm roberta base model trained with the LAION-5B ( https://laion.ai/blog/laion-5b/ ) using OpenCLIP ( https://github.com/mlfoundations/open_clip ).

Model training done by Romain Beaumont on the stability.ai cluster.

Uses

Direct Use

Zero-shot image classification, image and text retrieval, among others.

Downstream Use

Image classification and other image task fine-tuning, linear probe image classification, image generation guiding and conditioning, among others.

Training Details

Training Data

This model was trained with the full LAION-5B ( https://laion.ai/blog/laion-5b/ ).

Training Procedure

Training with batch size 90k for 13B sample of laion5B, see https://wandb.ai/rom1504/open-clip/reports/xlm-roberta-base-B-32--VmlldzoyOTQ5OTE2

Model is B/32 on visual side, xlm roberta base initialized with pretrained weights on text side.

Evaluation

Evaluation done with code in the LAION CLIP Benchmark suite .

Testing Data, Factors & Metrics

Testing Data

The testing is performed with VTAB+ (A combination of VTAB ( https://arxiv.org/abs/1910.04867 ) w/ additional robustness datasets) for classification and COCO and Flickr for retrieval.

Results

The model achieves

• imagenet 1k 62.33% (vs 62.9% for baseline)
• mscoco 63.4% (vs 60.8% for baseline)
• flickr30k 86.2% (vs 85.4% for baseline)

A preliminary multilingual evaluation was run: 43% on imagenet1k italian (vs 21% for english B/32), 37% for imagenet1k japanese (vs 1% for english B/32 and 50% for B/16 clip japanese). It shows the multilingual property is indeed there as expected. Larger models will get even better performance.
