shvit_s2 Fine-tuned on CIFAR-100

This model is a fine-tuned version of SHViT (Single-Head Vision Transformer) on the CIFAR-100 dataset.

SHViT is from the CVPR 2024 paper: SHViT: Single-Head Vision Transformer with Memory Efficient Macro Design by Seokju Yun and Youngmin Ro.

• Framework: PyTorch / timm

Performance

• Test Accuracy (100% data): 72.64%
• Data Efficiency Score: 0.411
• Data for 90% Performance: 77.5%

Dataset

CIFAR-100: 100-class image classification dataset

• Classes: 100
• Image Size: 32x32 → 224x224 (resized)

Training Details

This model was trained as part of a comprehensive analysis comparing SHViT with baseline models (DeiT-Tiny, MobileNetV2) across multiple dimensions:

• Robustness to corruptions (noise, blur, weather effects)
• Data efficiency across different training data fractions
• Geometric invariance (rotation, crop, color changes)
• Domain adaptation capabilities
• Representation similarity analysis

Training configuration:

• Optimizer: AdamW
• Learning rate schedule: Cosine decay
• Augmentation: RandAugment, Random Erasing
• Input size: 224×224

Usage

import torch
from timm import create_model

# Load model
model = create_model('shvit_s2', num_classes=100, pretrained=False)

# Load checkpoint
checkpoint = torch.hub.load_state_dict_from_url(
    'hf://YOUR_USERNAME/shvit_s2-cifar/checkpoint_99.pth'
)
model.load_state_dict(checkpoint['model'])
model.eval()

# Use for inference
# (your image preprocessing code here)

Or use with Hugging Face Hub:

from huggingface_hub import hf_hub_download
import torch

# Download checkpoint
checkpoint_path = hf_hub_download(
    repo_id="YOUR_USERNAME/shvit_s2-cifar",
    filename="checkpoint_99.pth"
)

# Load model (requires timm and the SHViT model definition)
checkpoint = torch.load(checkpoint_path)
# ... load into your model
