Model Card: ViT Fine-tuned on Food-101

Model Overview

This model is a fine-tuned version of google/vit-base-patch16-224-in21k on the Food-101 dataset. The Vision Transformer (ViT) architecture is leveraged for image classification tasks, particularly for recognizing and categorizing food items.

Model Details

Model Type: Vision Transformer (ViT)
Base Model: google/vit-base-patch16-224-in21k
Fine-tuning Dataset: Food-101
Number of Labels: 101 (corresponding to different food categories)

Performance

The model achieves the following results on the evaluation set:

Loss: 1.6262
Accuracy: 89.6%

Intended Uses & Limitations

Intended Use Cases

Image Classification: This model is designed for classifying images into one of 101 food categories, making it suitable for applications like food recognition in diet tracking, restaurant menu analysis, or food-related search engines.

Limitations

Dataset Bias: The model's performance may degrade when applied to food images that are significantly different from those in the Food-101 dataset, such as non-Western cuisines or images captured in non-standard conditions.
Generalization: While the model performs well on the Food-101 dataset, its ability to generalize to other food-related tasks or datasets is not guaranteed.
Input Size: The model expects input images of size 224x224 pixels. Images of different sizes should be resized accordingly.

Training and Evaluation Data

The model was fine-tuned on the Food-101 dataset, which consists of 101,000 images across 101 different food categories. Each category contains 1,000 images, with 750 used for training and 250 for testing. The dataset includes diverse food items but may be skewed towards certain cuisines or food types.

PyTorch: 2.4.0+cu121
Datasets: 2.21.0
Tokenizers: 0.19.1

Inference Example

To run inference using this model, you can load an image from the Food-101 dataset and classify it as follows:

python

from datasets import load_dataset
from transformers import pipeline
from PIL import Image
import requests
from io import BytesIO

# Load a sample image from the internet
image_url = "https://example.com/path-to-your-image.jpg"  # Replace with your image URL
response = requests.get(image_url)
image = Image.open(BytesIO(response.content))

# Load the fine-tuned model for image classification
classifier = pipeline(
    "image-classification",
    model="ashaduzzaman/vit-finetuned-food101"
)

# Run inference
result = classifier(image)
print(result)

Ethical Considerations

Bias: The Food-101 dataset primarily consists of popular Western dishes, which may introduce bias in the model’s predictions for non-Western food items.
Privacy: When using this model in applications, ensure that the images are sourced ethically and that privacy considerations are respected.
