🚀 Quick Start

Installation

pip install torch torchvision huggingface_hub pillow requests

Load and Use the Model

import torch
import torch.nn as nn
from torchvision import models, transforms
from huggingface_hub import hf_hub_download
from PIL import Image

# Configuration
REPO_ID = "Phoenix21/resnet18-cifar10-baseline"
FILENAME = "resnet18_cifar10_baseline.pth"

# 1. Initialize model architecture
model = models.resnet18(pretrained=False)
model.fc = nn.Linear(model.fc.in_features, 10)  # CIFAR-10 has 10 classes

# 2. Download and load weights
model_path = hf_hub_download(repo_id=REPO_ID, filename=FILENAME)
model.load_state_dict(torch.load(model_path, map_location=torch.device('cpu')))

# 3. Set to evaluation mode
model.eval()

# 4. Prepare image transformation
transform = transforms.Compose([
    transforms.Resize((32, 32)),
    transforms.ToTensor(),
    transforms.Normalize(mean=[0.4914, 0.4822, 0.4465], 
                         std=[0.2023, 0.1994, 0.2010])  # CIFAR-10 stats
])

# 5. Load and preprocess image
image = Image.open("your_image.jpg").convert("RGB")
input_tensor = transform(image).unsqueeze(0)

# 6. Make prediction
with torch.no_grad():
    output = model(input_tensor)
    probabilities = torch.nn.functional.softmax(output[0], dim=0)

# 7. Get results
classes = ['airplane', 'automobile', 'bird', 'cat', 'deer', 
           'dog', 'frog', 'horse', 'ship', 'truck']
confidence, prediction = torch.max(probabilities, 0)
print(f"Prediction: {classes[prediction]} ({confidence.item()*100:.2f}%)")

Intended Use

This model is specifically designed for research and benchmarking purposes. It serves as:

1. Baseline Model: For comparing against more robust architectures
2. Control Model: In the VisionDev-Copilot project's robustness evaluation
3. Test Subject: For studying failure modes under image distortions

🔬 Research Application

Robustness Benchmarking

This model is meant to be "stressed" with various image distortions to evaluate failure modes:

# Example: Applying Gaussian blur to test robustness
from torchvision.transforms import GaussianBlur

distortion_transform = transforms.Compose([
    transforms.Resize((32, 32)),
    GaussianBlur(kernel_size=5, sigma=2.0),  # Add distortion
    transforms.ToTensor(),
    transforms.Normalize(mean=[0.4914, 0.4822, 0.4465], 
                         std=[0.2023, 0.1994, 0.2010])
])

# Test model with distorted images
distorted_tensor = distortion_transform(image).unsqueeze(0)
with torch.no_grad():
    distorted_output = model(distorted_tensor)

Common Distortions to Test:

• Gaussian Blur (σ = 0.5-2.0)
• Shot/Impulse Noise (var = 0.01-0.1)
• JPEG Compression (quality = 10-90)
• Brightness/Contrast adjustments
• Pixelation effects

⚠️ Limitations

1. Low Resolution: Trained on 32×32 images, not suitable for high-resolution inputs
2. Limited Classes: Only recognizes the 10 CIFAR-10 categories
3. Sensitivity: Vulnerable to adversarial attacks and common image distortions
4. Domain Specific: Optimized for CIFAR-10, may not generalize well to other datasets
