# PyTorch Analysis Sub-module

## Overview

Framework-specific analysis module for PyTorch simulation outputs. Reads `simulation_results.json` produced by the PyTorch runner and generates belief trajectory, action distribution, and EFE analysis plots.

## Architecture

```

├── __init__.py # Package exports

└── analyzer.py # PyTorch result analysis and visualization (202 lines)

```

## Key Functions

- **`generate_analysis_from_logs(results_dir, output_dir=None, verbose=False)`** — Main entry point; reads PyTorch JSON results and produces matplotlib visualizations.

- **Belief trajectory plotting** — Tracks posterior belief evolution over simulation timesteps.

- **Action distribution analysis** — Visualizes policy distributions across actions.

## Dependencies

- `numpy`, `matplotlib` (required)

- `torch` (runtime, for result interpretation)

## Parent Module
