Model Card for CLIP ViT-H/14 frozen xlm roberta large - LAION-5B

Table of Contents

Model Details

Model Description

A CLIP ViT-H/14 frozen xlm roberta large 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-large-unfrozen-vit-h-14-frozen--VmlldzoyOTc3ODY3

Model is H/14 on visual side, xlm roberta large initialized with pretrained weights on text side.

The H/14 was initialized from https://huggingface.co/laion/CLIP-ViT-H-14-laion2B-s32B-b79K and kept frozen during training.

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 77.0% (vs 78% for the english H/14)

On zero shot classification on imagenet with translated prompts this model reaches:

• 56% in italian (vs 21% for https://github.com/clip-italian/clip-italian )
• 53% in japanese (vs 54.6% for https://github.com/rinnakk/japanese-clip )
• 55.7% in chinese (to be compared with https://github.com/OFA-Sys/Chinese-CLIP )

This model reaches strong results in both english and other languages.
