GNN-based trust propagation for AI systems

rotalabs-graph

GNN-based trust propagation for AI systems.

Features

• Trust Graph Data Structure: Model trust relationships between AI components

• Anomaly Detection: Detect circular trust, trust islands, and suspicious patterns
• Path Analysis: Find trust paths and bottlenecks between nodes
• Cluster Analysis: Identify trust communities using Louvain, label propagation, etc.
• Temporal Trust: Trust decay over time with history tracking
• Graph Metrics: Comprehensive metrics for trust health analysis

Installation

pip install rotalabs-graph

With GNN support (requires PyTorch):

pip install rotalabs-graph[gnn]

With visualization:

pip install rotalabs-graph[viz]

Quick Start

Create a Trust Graph

from datetime import datetime
from rotalabs_graph import TrustGraph, TrustNode, TrustEdge, NodeType, EdgeType

# Create graph
graph = TrustGraph()

# Add nodes
now = datetime.now()
graph.add_node(TrustNode(
    id="user-1",
    name="User",
    node_type=NodeType.USER,
    base_trust=1.0,
    created_at=now,
    updated_at=now,
))

graph.add_node(TrustNode(
    id="model-gpt4",
    name="GPT-4",
    node_type=NodeType.MODEL,
    base_trust=0.95,
    created_at=now,
    updated_at=now,
))

# Add trust edge
graph.add_edge(TrustEdge(
    source_id="user-1",
    target_id="model-gpt4",
    edge_type=EdgeType.TRUSTS,
    weight=0.9,
    created_at=now,
))

print(f"Graph: {graph.num_nodes} nodes, {graph.num_edges} edges")

Detect Anomalies

from rotalabs_graph import AnomalyDetector

detector = AnomalyDetector()
anomalies = detector.detect_all(graph)

for anomaly in anomalies:
    print(f"{anomaly.anomaly_type}: {anomaly.description}")

Find Trust Paths

from rotalabs_graph import PathAnalyzer

analyzer = PathAnalyzer()
paths = analyzer.find_all_paths(graph, "user-1", "model-gpt4")

for path in paths:
    print(f"Path: {' -> '.join(path.node_ids)}, trust: {path.path_trust:.3f}")

Temporal Trust with Decay

from rotalabs_graph import TemporalTrustGraph, DecayFunction

# Create temporal graph with exponential decay
graph = TemporalTrustGraph(
    decay_function=DecayFunction.EXPONENTIAL,
    half_life_days=30.0,
    track_history=True,
)

# Add node
graph.add_node("agent-1", initial_trust=0.9)

# Get current trust (with decay applied)
current = graph.get_current_trust("agent-1")
