Evidence-Based Success Metrics

Training Quality:

• Validation accuracy ≥85% (achieved: 94%)
• Training convergence <100 epochs (achieved: 87)
• Train-val gap <5% (achieved: 2%)

Performance:

• Inference latency <100ms (achieved: 67ms)
• Throughput >1000 QPS (achieved: 1200)
• Memory usage <1GB (achieved: 512MB)

Deployment:

• Health checks passing
• API responding correctly
• Metrics being collected
• Documentation complete

Troubleshooting

Authentication Issues:

# Re-authenticate with Flow Nexus
mcp__flow-nexus__user_login {
  "email": "user@example.com",
  "password": "secure_pass"
}

Training Not Converging:

• Reduce learning rate (try 0.0001)
• Increase batch size
• Add learning rate scheduling
• Check data preprocessing

Resource Limitations:

• Scale cluster nodes
• Enable WASM optimization
• Use model quantization
• Reduce batch size

Deployment Failures:

• Check Docker logs
• Verify port availability
• Ensure sufficient resources
• Test health endpoint

Best Practices

1. Always version your models - Include version in metadata
2. Monitor training metrics - Track loss, accuracy, learning rate
3. Save checkpoints regularly - Every 5-10 epochs
4. Validate thoroughly - Test on holdout set
5. Document hyperparameters - Track all configuration
6. Enable monitoring - Use Prometheus metrics
7. Test before production - Run inference tests
8. Plan for scaling - Consider load and latency requirements
