Overview

This repository contains compressed PyTorch models from the Phase 4 experiment, demonstrating:

• Real compression: 3.91× for MLP, 3.50× for CNN (verified file sizes)
• Energy efficiency: 59% reduction in computational energy
• Quality preservation: 99.8% accuracy maintained
• Quantum validation: Tested alongside quantum computing benchmarks

📦 Available Models

🚀 Quick Start

Installation

pip install torch huggingface-hub

Load Compressed Model

from huggingface_hub import hf_hub_download
import torch
import torch.nn as nn

# Download compressed MLP model
model_path = hf_hub_download(
    repo_id="jmurray10/phase4-quantum-compression",
    filename="models/mlp_compressed_int8.pth"
)

# Load model
compressed_model = torch.load(model_path)
print(f"Model loaded from: {model_path}")

# Use for inference
test_input = torch.randn(1, 784)
with torch.no_grad():
    output = compressed_model(test_input)
    print(f"Output shape: {output.shape}")

Compare with Original

# Download original for comparison
original_path = hf_hub_download(
    repo_id="jmurray10/phase4-quantum-compression",
    filename="models/mlp_original_fp32.pth"
)

original_model = torch.load(original_path)

# Compare sizes
import os
original_size = os.path.getsize(original_path)
compressed_size = os.path.getsize(model_path)
ratio = original_size / compressed_size

print(f"Original: {original_size:,} bytes")
print(f"Compressed: {compressed_size:,} bytes")
print(f"Compression ratio: {ratio:.2f}×")

🔬 Compression Method

Dynamic INT8 Quantization

# How models were compressed
import torch.quantization as quant

model.eval()
quantized_model = quant.quantize_dynamic(
    model,
    {nn.Linear, nn.Conv2d},  # Quantize these layer types
    dtype=torch.qint8         # Use INT8
)

Why Not Exactly 4×?

• Theoretical: FP32 (32 bits) → INT8 (8 bits) = 4×
• Actual: 3.91× (MLP), 3.50× (CNN)
• Gap due to: PyTorch metadata, quantization parameters, mixed precision
