PoE-World Integration with GNN

📋 Document Metadata
Type: Integration Guide | Audience: Researchers, Developers | Complexity: Advanced
Cross-References: PoE-World Overview | GNN Advanced Patterns | LLM Integration

Overview

This document explores the integration of PoE-World (Products of Programmatic Experts for World Modeling) with GNN (Generalized Notation Notation) for Active Inference modeling. The synergy between these approaches enables:

  • Compositional World Models: Express PoE-World's modular expert structure using GNN notation
  • Active Inference Integration: Embed PoE-World dynamics within Active Inference frameworks
  • LLM-Enhanced GNN: Leverage program synthesis for automated GNN model generation
  • Interpretable AI: Combine the interpretability of both frameworks for explainable world modeling

🔗 Related Work: PoE-World builds on program synthesis and LLM-based code generation, areas where GNN can provide structured representation and validation capabilities.

PoE-World Technical Architecture Mapping

Core System Components in GNN Context

PoE-World's hierarchical architecture maps naturally to GNN's factor-based representation:

Agent System (agents/)Policy Factors (π_c0, u_c0) Learning Framework (learners/)Hidden State Factors (s_f0, s_f1, ...) Environment Classes (classes/)Observation Modalities (o_m0, o_m1, ...) Configuration Management (conf/)GNN Model Parameters

PoE-World Agent to GNN Factor Mapping

The PoE-World Agent class orchestrates three main phases that correspond to GNN factors:

# PoE-World Agent Structure
class Agent:
    def __init__(self, config: Dict[str, Any], world_learner: WorldModelLearner):
        self.world_learner = world_learner  # → s_f_world_knowledge
        self.mcts = MCTS(config)           # → π_c0 planning_policy
        self.abstract_planning = True      # → s_f_planning_mode

GNN Representation:

### Agent System Factors
s_f_world_knowledge[world_size, 1, type=categorical]    ### PoE-World WorldModelLearner state
s_f_planning_mode[2, 1, type=categorical]              ### Abstract vs concrete planning
s_f_mcts_state[tree_depth, 1, type=categorical]       ### Current MCTS search state
π_c0[action_space, 1, type=continuous]                ### MCTS-derived policy

Conceptual Alignment with Technical Details

PoE-World Mathematical Foundation in Practice

PoE-World implements the product of experts as:

# From learners/synthesizer.py - Expert combination
class PoEWorldLearner(WorldModelLearner):
    def __init__(self, config: DictConfig):
        self.obj_model_learners: Dict[str, ObjModelLearner] = {}  # Individual experts
        self.all_obj_types: Optional[List[str]] = None           # Expert categories

This maps to GNN as hierarchical Active Inference where:

  • Expert Learners (obj_model_learners) → Specialized State Factors (s_f_expert_i)
  • Object Types (all_obj_types) → Expert Categories in state space
  • Model CompositionGNN Connection Patterns between factors

2. Configuration-Based Model Generation

Hydra Config to GNN Translation:

def generate_gnn_from_poe_config(config_path: str) -> GNNModel:
    """Generate GNN model from PoE-World Hydra configuration"""
    
    # Load PoE-World configuration
    with initialize(config_path="conf"):
        config = compose(config_name=config_path)
    
    # Extract relevant parameters
    task_name = config.task
    agent_params = config.agent
    synthesis_params = config.synthesis
    
    # Create task-specific GNN factors
    task_factors = create_task_specific_factors(task_name)
    agent_factors = create_agent_factors(agent_params)
    synthesis_factors = create_synthesis_factors(synthesis_params)
    
    # Combine into complete GNN model
    all_factors = {**task_factors, **agent_factors, **synthesis_factors}
    connections = infer_factor_connections(all_factors, config)
    
    return GNNModel(
        name=f"PoEWorld_{task_name}_GNN",
        factors=all_factors,
        connections=connections,
        parameters=extract_gnn_parameters(config)
    )

3. Parallel Processing Integration

SLURM Job Management with GNN:

class GNNParallelProcessor:
    """Integrate PoE-World's parallel processing with GNN updates"""
    
    def __init__(self, gnn_model: GNNModel, slurm_config: Dict[str, Any]):
        self.gnn_model = gnn_model
        self.slurm_config = slurm_config
        self.job_queue = SLURMJobQueue(slurm_config)
        self.gnn_updater = ParallelGNNUpdater(gnn_model)
    
    def parallel_expert_synthesis(self, state_transitions: List[StateTransitionTriplet]) -> Dict[str, List[str]]:
        """Parallelize expert synthesis across compute nodes with GNN coordination"""
        
        # Partition synthesis tasks
        synthesis_jobs = self.partition_synthesis_tasks(state_transitions)
        
        # Submit parallel jobs with GNN context
        job_ids = []
        for job_data in synthesis_jobs:
            gnn_context = self.gnn_model.get_synthesis_context()
            job_id = self.job_queue.submit_synthesis_job(job_data, gnn_context)
            job_ids.append(job_id)
        
        # Collect results and update GNN
        synthesis_results = {}
        for job_id in job_ids:
            result = self.job_queue.wait_for_completion(job_id)
            synthesis_results[job_id] = result
            
            # Update GNN factors with parallel results
            self.gnn_updater.update_from_parallel_result(result)
        
        return synthesis_results
