Overview

Developed by: HAKUHODO Technologies Inc.
Model type: Contrastive Language-Image Pre-trained Model
Language(s): Japanese
LICENSE: CC BY-NC-SA 4.0

Presented here is a Japanese CLIP (Contrastive Language-Image Pre-training) model, mapping Japanese texts and images to a unified embedding space. Capable of multimodal tasks including zero-shot image classification, text-to-image retrieval, and image-to-text retrieval, this model extends its utility when integrated with other components, contributing to generative models like image-to-text and text-to-image generation.

Usage

Dependencies

python3 -m pip install pillow sentencepiece torch torchvision transformers

Inference

The usage is similar to CLIPModel and VisionTextDualEncoderModel.

import requests
import torch
from PIL import Image
from transformers import AutoModel, AutoProcessor, BatchEncoding

# Download
model_name = "hakuhodo-tech/japanese-clip-vit-h-14-bert-base"
device = "cuda" if torch.cuda.is_available() else "cpu"
model = AutoModel.from_pretrained(model_name, trust_remote_code=True).to(device)
processor = AutoProcessor.from_pretrained(model_name, trust_remote_code=True)

# Prepare raw inputs
url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)

# Process inputs
inputs = processor(
    text=["犬", "猫", "象"],
    images=image,
    return_tensors="pt",
    padding=True,
)

# Infer and output
outputs = model(**BatchEncoding(inputs).to(device))
probs = outputs.logits_per_image.softmax(dim=1)
print([f"{x:.2f}" for x in probs.flatten().tolist()])  # ['0.00', '1.00', '0.00']

Model Details

Components

The model consists of a frozen ViT-H image encoder from laion/CLIP-ViT-H-14-laion2B-s32B-b79K and a 12-layer 12-head BERT text encoder initialized from rinna/japanese-clip-vit-b-16.

Training

Model training is done by Zhi Wang with 8 A100 (80 GB) GPUs. Locked-image Tuning (LiT) is adopted. See more details in the paper.

Dataset

The Japanese subset of the laion2B-multi dataset containing ~120M image-text pairs.

Evaluation

Testing Data

The 5K evaluation set (val2017) of MS-COCO with STAIR Captions.

Metrics

Zero-shot image-to-text and text-to-image recall@1, 5, 10.

Results


	Text Retrieval			Image Retrieval

Japanese CLIP ViT-H/14 (Deeper)	48.7	74.0	82.4	36.5	61.5	71.8
Japanese CLIP ViT-H/14 (Wider)	47.9	74.2	83.2	37.3	62.8	72.7

* Japanese Stable CLIP ViT-L/16 is excluded for zero-shot retrieval evaluation as the model was partially pre-trained with MS-COCO.

Limitations and Biases

Despite our data filtering, it is crucial to acknowledge the possibility of the training dataset containing offensive or inappropriate content. Users should be mindful of the potential societal impact and ethical considerations associated with the outputs generated by the model when deploying in production systems. It is recommended not to employ the model for applications that have the potential to cause harm or distress to individuals or groups.
