## Usage

### Basic Example

```typescript
import { DSPyAgenticSynthTrainer } from './training/dspy-real-integration.js';

// Define your data schema
const schema = {
  type: 'object',
  properties: {
    userId: { type: 'string' },
    name: { type: 'string' },
    email: { type: 'string', format: 'email' },
    age: { type: 'number' }
  }
};

// Provide initial training examples
const examples = [
  {
    input: JSON.stringify(schema),
    output: JSON.stringify({
      userId: '123',
      name: 'Alice',
      email: 'alice@example.com',
      age: 28
    }),
    quality: 0.9
  }
];

// Configure trainer
const trainer = new DSPyAgenticSynthTrainer({
  models: ['gpt-3.5-turbo'],
  optimizationRounds: 5,
  minQualityScore: 0.8,
  batchSize: 10
});

// Initialize and train
await trainer.initialize();
const result = await trainer.trainWithOptimization(schema, examples);

// Generate optimized data
const data = await trainer.generateOptimizedData(100, schema);
```

### Advanced Configuration

```typescript
const trainer = new DSPyAgenticSynthTrainer({
  // Models to use for training
  models: [
    'gpt-3.5-turbo',
    'gpt-4',
    'claude-3-sonnet-20240229'
  ],

  // Training parameters
  optimizationRounds: 10,
  minQualityScore: 0.85,
  maxExamples: 100,
  batchSize: 20,

  // Evaluation metrics
  evaluationMetrics: ['accuracy', 'coherence', 'relevance', 'diversity'],

  // Performance options
  enableCaching: true,

  // Event hooks
  hooks: {
    onIterationComplete: (iteration, metrics) => {
      console.log(`Iteration ${iteration}: ${metrics.overallScore}`);
    },
    onOptimizationComplete: (result) => {
      console.log(`Improvement: ${result.improvements.improvement}%`);
    },
    onError: (error) => {
      console.error('Training error:', error);
    }
  }
});
```

### Event Monitoring

```typescript
// Listen to training events
trainer.on('status', (message) => {
  console.log('Status:', message);
});

trainer.on('progress', ({ current, total }) => {
  console.log(`Progress: ${current}/${total}`);
});

trainer.on('complete', (result) => {
  console.log('Training complete:', result);
});

trainer.on('error', (error) => {
  console.error('Error:', error);
});
```

## Integration with Agentic-Synth

### Extending BaseGenerator

```typescript
import { BaseGenerator } from '../src/generators/base.js';
import { DSPyAgenticSynthTrainer } from './dspy-real-integration.js';

class OptimizedGenerator extends BaseGenerator {
  private trainer: DSPyAgenticSynthTrainer;

  constructor(config: SynthConfig) {
    super(config);
    this.trainer = new DSPyAgenticSynthTrainer({
      models: ['gpt-3.5-turbo'],
      minQualityScore: 0.8
    });
  }

  async generateWithOptimization(options: GeneratorOptions) {
    await this.trainer.initialize();

    // Use existing generation as training examples
    const initial = await this.generate(options);
    const examples = initial.data.map(item => ({
      input: JSON.stringify(options.schema),
      output: JSON.stringify(item),
      quality: 0.7
    }));

    // Train and optimize
    await this.trainer.trainWithOptimization(
      options.schema || {},
      examples
    );

    // Generate optimized data
    return this.trainer.generateOptimizedData(
      options.count || 10,
      options.schema
    );
  }
}
```

## How It Works

### Phase 1: Initialization
1. Initialize OpenAI/Anthropic language models via dspy.ts
2. Configure ChainOfThought module for reasoning
3. Set up BootstrapFewShot optimizer

### Phase 2: Baseline Generation
1. Generate initial data with each configured model
2. Evaluate quality using dspy.ts metrics
3. Collect successful examples (above threshold)

### Phase 3: Optimization Rounds
1. Train BootstrapFewShot with successful examples
2. Compile optimized program with learned prompts
3. Generate new data with optimized program
4. Evaluate and update training set
5. Repeat until convergence or max rounds

### Phase 4: Production Generation
1. Use optimized program for data generation
2. Batch processing for efficiency
3. Real-time quality monitoring
4. Return high-quality synthetic data

## DSPy.ts Features Used

### Modules
- `ChainOfThought` - Multi-step reasoning for quality assessment
- `BootstrapFewShot` - Automatic few-shot learning optimizer

### Language Models
- `OpenAILM` - GPT-3.5, GPT-4 support
- `AnthropicLM` - Claude models support
- `configureLM()` - Switch between models

### Evaluation
- `evaluate()` - Batch evaluation of examples
- `exactMatch()` - Exact string matching metric
- `f1Score()` - F1 score calculation

### Optimization
- Automatic prompt optimization
- Few-shot example selection
- Quality-driven learning

## Performance

### Benchmarks

- **Initial Quality**: ~0.70-0.75
- **Optimized Quality**: ~0.85-0.90
- **Improvement**: 15-25%
- **Convergence**: 3-5 rounds typically
- **Speed**: ~2-5s per iteration (GPT-3.5)

### Optimization

- Caching enabled by default
- Batch processing for efficiency
- Parallel model evaluation
- Convergence detection to avoid unnecessary rounds

## Best Practices

### 1. Provide Quality Examples

```typescript
const examples = [
  {
    input: JSON.stringify(schema),
    output: JSON.stringify(highQualityData),
    quality: 0.9  // High quality score
  }
];
```

### 2. Start with Baseline Models

```typescript
// Start simple, then add advanced models
models: [
  'gpt-3.5-turbo',    // Fast baseline
  'gpt-4'             // High quality
]
```

### 3. Monitor Progress

```typescript
hooks: {
  onIterationComplete: (iteration, metrics) => {
    // Track progress
    if (metrics.overallScore > 0.9) {
      console.log('Excellent quality achieved!');
    }
  }
}
```

### 4. Set Realistic Thresholds

```typescript
{
  minQualityScore: 0.8,  // Achievable target
  optimizationRounds: 5   // Balance quality vs. cost
}
```

## Troubleshooting

### API Key Issues

```
Error: OPENAI_API_KEY not set
```

**Solution:** Set environment variable:
```bash
export OPENAI_API_KEY="sk-..."
```

### Low Quality Scores

**Solution:**
- Provide better training examples
- Increase optimization rounds
- Lower quality threshold initially
- Try different models

### Slow Performance

**Solution:**
- Reduce batch size
- Enable caching
- Use faster models (gpt-3.5-turbo)
- Lower optimization rounds

### Module Import Errors

**Solution:**
```bash
# Ensure dependencies are installed
npm install

# Check dspy.ts version
npm list dspy.ts
```
