# AgentDB Learning Plugins

## What This Skill Does

Provides access to 9 reinforcement learning algorithms via AgentDB's plugin system. Create, train, and deploy learning plugins for autonomous agents that improve through experience. Includes offline RL (Decision Transformer), value-based learning (Q-Learning), policy gradients (Actor-Critic), and advanced techniques.

**Performance**: Train models 10-100x faster with WASM-accelerated neural inference.

## Prerequisites

- Node.js 18+
- AgentDB v1.0.7+ (via agentic-flow)
- Basic understanding of reinforcement learning (recommended)

## Training Workflow

### 1. Collect Experiences

```typescript
// Store experiences during agent execution
for (let i = 0; i < numEpisodes; i++) {
  const episode = runEpisode();

  for (const step of episode.steps) {
    await adapter.insertPattern({
      id: '',
      type: 'experience',
      domain: 'task-domain',
      pattern_data: JSON.stringify({
        embedding: await computeEmbedding(JSON.stringify(step)),
        pattern: {
          state: step.state,
          action: step.action,
          reward: step.reward,
          next_state: step.next_state,
          done: step.done,
        },
      }),
      confidence: step.reward > 0 ? 0.9 : 0.5,
      usage_count: 1,
      success_count: step.reward > 0 ? 1 : 0,
      created_at: Date.now(),
      last_used: Date.now(),
    });
  }
}
```

### 2. Train Model

```typescript
// Train on collected experiences
const trainingMetrics = await adapter.train({
  epochs: 100,
  batchSize: 64,
  learningRate: 0.001,
  validationSplit: 0.2,
});

console.log('Training Metrics:', trainingMetrics);
// {
//   loss: 0.023,
//   valLoss: 0.028,
//   duration: 1523,
//   epochs: 100
// }
```

### 3. Evaluate Performance

```typescript
// Retrieve similar successful experiences
const testQuery = await computeEmbedding(JSON.stringify(testState));
const result = await adapter.retrieveWithReasoning(testQuery, {
  domain: 'task-domain',
  k: 10,
  synthesizeContext: true,
});

// Evaluate action quality
const suggestedAction = result.memories[0].pattern.action;
const confidence = result.memories[0].similarity;

console.log('Suggested Action:', suggestedAction);
console.log('Confidence:', confidence);
```

---

## Advanced Training Techniques

### Experience Replay

```typescript
// Store experiences in buffer
const replayBuffer = [];

// Sample random batch for training
const batch = sampleRandomBatch(replayBuffer, batchSize: 32);

// Train on batch
await adapter.train({
  data: batch,
  epochs: 1,
  batchSize: 32,
});
```

### Prioritized Experience Replay

```typescript
// Store experiences with priority (TD error)
await adapter.insertPattern({
  // ... standard fields
  confidence: tdError, // Use TD error as confidence/priority
  // ...
});

// Retrieve high-priority experiences
const highPriority = await adapter.retrieveWithReasoning(queryEmbedding, {
  domain: 'task-domain',
  k: 32,
  minConfidence: 0.7, // Only high TD-error experiences
});
```

### Multi-Agent Training

```typescript
// Collect experiences from multiple agents
for (const agent of agents) {
  const experience = await agent.step();

  await adapter.insertPattern({
    // ... store experience with agent ID
    domain: `multi-agent/${agent.id}`,
  });
}

// Train shared model
await adapter.train({
  epochs: 50,
  batchSize: 64,
});
```

---

## Performance Optimization

### Batch Training

```typescript
// Collect batch of experiences
const experiences = collectBatch(size: 1000);

// Batch insert (500x faster)
for (const exp of experiences) {
  await adapter.insertPattern({ /* ... */ });
}

// Train on batch
await adapter.train({
  epochs: 10,
  batchSize: 128,  // Larger batch for efficiency
});
```

### Incremental Learning

```typescript
// Train incrementally as new data arrives
setInterval(async () => {
  const newExperiences = getNewExperiences();

  if (newExperiences.length > 100) {
    await adapter.train({
      epochs: 5,
      batchSize: 32,
    });
  }
}, 60000); // Every minute
```

---

## Integration with Reasoning Agents

Combine learning with reasoning for better performance:

```typescript
// Train learning model
await adapter.train({ epochs: 50, batchSize: 32 });

// Use reasoning agents for inference
const result = await adapter.retrieveWithReasoning(queryEmbedding, {
  domain: 'decision-making',
  k: 10,
  useMMR: true, // Diverse experiences
  synthesizeContext: true, // Rich context
  optimizeMemory: true, // Consolidate patterns
});

// Make decision based on learned experiences + reasoning
const decision = result.context.suggestedAction;
const confidence = result.memories[0].similarity;
```

# Create plugin
npx agentdb@latest create-plugin -t decision-transformer -n my-plugin

# List plugins
npx agentdb@latest list-plugins

# Get plugin info
npx agentdb@latest plugin-info my-plugin

## Troubleshooting

### Issue: Training not converging

```typescript
// Reduce learning rate
await adapter.train({
  epochs: 100,
  batchSize: 32,
  learningRate: 0.0001, // Lower learning rate
});
```

### Issue: Overfitting

```typescript
// Use validation split
await adapter.train({
  epochs: 50,
  batchSize: 64,
  validationSplit: 0.2, // 20% validation
});

// Enable memory optimization
await adapter.retrieveWithReasoning(queryEmbedding, {
  optimizeMemory: true, // Consolidate, reduce overfitting
});
```

### Issue: Slow training

```bash
# Enable quantization for faster inference
# Use binary quantization (32x faster)
```
