Visual Common Sense Reasoning

A production-ready implementation of advanced visual common sense reasoning using state-of-the-art Vision-Language models. This project demonstrates how AI systems can understand visual scenes and make common sense inferences about object interactions, spatial relationships, and implicit knowledge.

Features

• Multiple VL Models: CLIP, BLIP, and ensemble approaches for robust reasoning
• Comprehensive Evaluation: Accuracy, precision, recall, F1, confidence calibration, and more
• Interactive Demo: Streamlit-based web application for real-time visual reasoning
• Modern Architecture: Clean, typed code with proper error handling and logging
• Device Flexibility: Automatic CUDA → MPS → CPU fallback
• Reproducible: Deterministic seeding and comprehensive configuration management
• Production Ready: Proper project structure, testing, and documentation

Quick Start

Installation

# Clone the repository
git clone https://github.com/kryptologyst/Visual-Common-Sense-Reasoning.git
cd Visual-Common-Sense-Reasoning

# Install dependencies
pip install -r requirements.txt

# Or install with optional dependencies
pip install -e ".[dev,tracking,serving]"

Basic Usage

from src.models.visual_reasoning import VisualReasoningPipeline
from src.utils.core import get_device

# Initialize pipeline
device = get_device()
pipeline = VisualReasoningPipeline(model_type="clip", device=device)

# Perform reasoning
result = pipeline.reason_about_image(
    image_path="path/to/image.jpg",
    prompts=[
        "a person is sitting on a chair",
        "a dog is running in the park",
        "a cat is sleeping on the couch"
    ]
)

print(f"Predicted: {result['predicted_prompt']}")
print(f"Confidence: {result['confidence']:.2%}")

Interactive Demo

# Launch Streamlit demo
streamlit run demo/app.py

The demo provides an intuitive interface to:

• Upload images for analysis
• Test different reasoning prompts
• Compare model predictions and confidence scores
• Visualize probability distributions
• Explore ensemble model results

Models

CLIP (Contrastive Language-Image Pre-training)

• Use Case: Zero-shot visual reasoning and image-text matching
• Strengths: Strong semantic understanding, fast inference
• Best For: Common sense reasoning, object interaction understanding

BLIP (Bootstrapping Language-Image Pre-training)

• Use Case: Visual question answering and image captioning
• Strengths: Generative capabilities, detailed scene understanding
• Best For: Complex reasoning tasks, detailed descriptions

Ensemble

• Use Case: Robust predictions combining multiple models
• Strengths: Improved accuracy, reduced uncertainty
• Best For: Production systems requiring high reliability

Evaluation Metrics

The project includes comprehensive evaluation metrics:

• Accuracy: Exact match accuracy for predictions
• Precision/Recall/F1: Weighted averages across classes
• Confidence Metrics: Mean, std, min, max confidence scores
• Calibration: Expected Calibration Error (ECE) and Maximum Calibration Error (MCE)
• Efficiency: Inference time, memory usage, model size

Configuration

The project uses Hydra for configuration management. Key configuration files:
