Execution Checklist

• Design neural architecture for task requirements
• Select appropriate training tier based on model size
• Configure training hyperparameters
• Initialize training (single or distributed)
• Monitor training progress and metrics
• Validate model performance
• Run benchmarks for production readiness
• Deploy for inference or publish as template
• Cleanup cluster resources when complete

Best Practices

1. Start Small: Begin with nano or mini tier for testing, scale up for production
2. Proper Validation: Always run validation workflow before production deployment
3. Hyperparameter Tuning: Use grid search or Bayesian optimization for best results
4. Distributed Training: Use for large models; single-node for smaller experiments
5. Checkpoint Frequently: Enable checkpointing for long training runs
6. Monitor Drift: Implement drift detection for production models

Error Handling

Metrics & Success Criteria

• Training Convergence: Loss decreasing over epochs
• Validation Accuracy: Target >90% for classification
• Inference Latency: <100ms for production
• Memory Efficiency: <80% resource utilization
• Model Size: Appropriate for deployment target
