AI_Trajectory_Monitor

KL divergence approach to predict training scaling and optimize reasoning scaling in emergent AI models

AI Trajectory Monitor

Predictive framework for AI learning health, alignment monitoring, and capability emergence forecasting

---

====The Problem====

Current AI evaluation is like checking a car's speedometer without looking at the road. We measure performance metrics (accuracy, loss) but miss critical questions:

• Is the AI learning what we want, or gaming our metrics? (Reward hacking)
• Will the AI maintain its values over time? (Temporal identity drift)
• Can we predict when new capabilities will emerge? (Scaling trajectory forecasting)

====Solution====

A mathematical framework that gives AI systems self-auditing capabilities to monitor their own learning in real-time, detecting three critical failure modes:

###Reward Hacking Detection "Am I optimizing for what humans want, or what's easy to measure?"

###Temporal Identity Drift Monitoring
"Am I still the same AI I was supposed to be?"

###Learning Trajectory Forecasting "Where is my learning headed, and when will I hit capability thresholds?"

====Quick Demo====

from trajectory_monitor import AITrajectoryMonitor
import numpy as np

# Initialize monitoring system
monitor = AITrajectoryMonitor(
    competency_dims=['accuracy', 'reasoning', 'alignment', 'efficiency'],
    complexity_penalty=0.1,
    drift_threshold=0.3
)

# Simulate training loop with potential reward hacking
for epoch in range(1000):
    # Your model training step here
    current_state = get_model_state(model, epoch)
    
    # Monitor learning health
    health_report = monitor.audit_learning_step(
        current_state=current_state,
        reward_signal=reward_signal[epoch],
        timestamp=epoch
    )
    
    # Catch problems early
    if health_report['warnings']['reward_hacking']['confidence'] > 0.7:
        print(f"⚠️  Reward hacking detected at epoch {epoch}")
        print(f"Vibe-structure correlation: {health_report['vibe_structure_correlation']:.3f}")
        
    if health_report['warnings']['identity_drift']:
        print(f"🔄 Identity drift detected - AI values changing")
        
    # Forecast capability emergence
    if health_report['capability_emergence_probability'] > 0.8:
        print(f"🎯 Major capability jump predicted in ~{health_report['emergence_eta']} steps")

Output Example:

⚠️  Reward hacking detected at epoch 342
Vibe-structure correlation: 0.23
🔄 Identity drift detected - AI values changing  
🎯 Major capability jump predicted in ~89 steps

🧮 Mathematical Foundation

Core Learning State Vector

L(t) = [accuracy(t), reasoning(t), alignment(t), efficiency(t), coherence(t)]

KL Divergence Tracking

D_KL(t) = Σ P_ideal(c_i,t) * log(P_ideal(c_i,t) / P_actual(c_i,t))

Complexity-Penalized Learning Velocity

V_s(t) = V'(t) - λ * ∇C(L(t))

Key Innovation: We track the relationship between measurable performance and emergent learning quality. Healthy learning shows high correlation - when they diverge, you're likely seeing reward hacking or alignment drift.

📊 What It Detects

Failure Mode	Traditional Metrics	Our Detection
Reward Hacking	✅ High accuracy	⚠️ Degrading explanations despite good metrics
Capability Gaming	✅ Benchmark success	⚠️ Brittle performance on slight variations
Identity Drift	✅ Consistent performance	⚠️ Value system slowly changing over time
Learning Collapse	✅ Stable loss curves	⚠️ Reasoning quality breakdown

====Installation====

git clone https://github.com/relationalai-labs/AI_trajectory_monitor.git
cd ai-trajectory-monitor
pip install -r requirements.txt

Requirements:

• Python 3.8+
• NumPy, SciPy
• PyTorch or TensorFlow (for model integration)
• Matplotlib (for visualization)

====Usage Examples====

1. Training Monitoring

# Monitor your existing training loop
monitor = AITrajectoryMonitor()

for batch in dataloader:
    # Your normal training
    loss = train_step(model, batch)
    
    # Add trajectory monitoring
    audit = monitor.audit_step(model.state_dict(), loss, batch_idx)
    
    # Get predictive insights
    if audit.predicts_capability_jump():
        prepare_for_emergence(audit.emergence_timeline)

2. Goodhart's Law Stress Test

# Simulate reward corruption to test detection
corruption_levels = np.linspace(0, 0.8, 100)

for corruption in corruption_levels:
    corrupted_reward = corrupt_signal(true_reward, corruption)
    audit = monitor.audit_step(model_state, corrupted_reward)
    
    # Framework should detect gaming when corruption > 0.3
    assert audit.reward_hacking_confidence > 0.5 when corruption > 0.3

3. Long-term Identity Tracking

# Track AI consistency over months of training
identity_tracker = TemporalCoherenceMonitor(lookback_window=10000)

# Should maintain core values while improving capabilities
coherence_score = identity_tracker.measure_identity_drift(
    current_values=extract_ai_values(model),
    historical_window=last_10k_interactions
)

====Future: Test-Time Compute Era====

While this framework currently focuses on training-time monitoring, we're actively developing extensions for the emerging "test-time compute" paradigm where AI systems reason for extended periods before responding. Our mathematical foundations (KL divergence, temporal coherence) apply directly to reasoning chain monitoring.

Coming Soon: Reasoning health monitoring for o1-style models, chain-of-thought coherence tracking, and test-time alignment verification.

Built with the philosophy that AI systems should be able to ask themselves: "Am I still learning what I'm supposed to learn?"
