Vision Transformer (ViT) Fine-tuned on Food101 Subset

Model Description

This model is a fine-tuned version of google/vit-base-patch16-224 for food image classification across 10 categories.

Classes

• pizza
• sushi
• hamburger
• ice_cream
• steak
• baklava
• cheesecake
• pancakes
• tacos
• ramen

Evaluation Results

Training Logs

Training Summary:

• Total steps: 1,175
• Final training loss: 0.2446
• Training runtime: 2,705 seconds (~45 minutes)
• Throughput: 13.86 samples/second

Reproduce Evaluation

from datasets import load_dataset
from transformers import pipeline
from tqdm import tqdm

# Load model
classifier = pipeline("image-classification", model="Nav772/vit-food-classifier", device=0)

# Load same test split
dataset = load_dataset("food101", split="validation")

# Filter to same 10 classes
selected_classes = ["pizza", "sushi", "hamburger", "ice_cream", "steak", 
                    "baklava", "cheesecake", "pancakes", "tacos", "ramen"]
class_names = dataset.features['label'].names
selected_indices = [class_names.index(c) for c in selected_classes]

filtered = dataset.filter(lambda x: x['label'] in selected_indices)

# Evaluate
correct = 0
total = 0

for example in tqdm(filtered):
    pred = classifier(example['image'])[0]['label']
    true_label = class_names[example['label']]
    if pred == true_label:
        correct += 1
    total += 1

print(f"Accuracy: {correct/total:.4f} ({correct}/{total})")

Training Data

• Dataset: Food101 (subset)
• Train samples: ~7,500 images
• Validation samples: ~2,500 images
• Classes: 10 food categories

Training Procedure

• Base model: google/vit-base-patch16-224
• Epochs: 5
• Batch size: 32
• Learning rate: 3e-5
• Image size: 224x224
• Mixed precision: FP16
• Warmup ratio: 0.1
• Weight decay: 0.01

Usage

from transformers import pipeline

classifier = pipeline("image-classification", model="Nav772/vit-food-classifier")
result = classifier("path/to/food/image.jpg")
print(result)

Limitations

• Only classifies 10 specific food categories
• May not generalize to food items outside these categories
• Performance may degrade on low-quality or obscured images
