AI Development Essentials
Key strategies for successful artificial intelligence projects
Data Preparation
-
Clean Your Data First
80% of AI work is data preparation. Handle missing values, remove duplicates, and normalize formats.
-
Labeling Matters
Invest in high-quality labeled data. Poor labels lead to poor model performance regardless of algorithm.
-
Understand Your Data Distribution
Visualize and analyze feature distributions before model selection.
Model Development
-
Start Simple
Begin with baseline models (linear regression, decision trees) before complex neural networks.
-
Balance Bias-Variance
Regularize models to prevent overfitting while maintaining predictive power.
-
Track Experiments
Use tools like MLflow or Weights & Biases to log parameters and results.
Production Deployment
-
Monitor Model Drift
Implement systems to detect when real-world data diverges from training data.
-
Optimize for Inference
Use quantization, pruning, and distillation to reduce model size and latency.
-
Secure Your Models
Protect against adversarial attacks and ensure data privacy compliance.
Ethical Considerations
-
Audit for Bias
Test models across demographic groups to identify unfair disparities.
-
Explainability
Use SHAP, LIME, or other techniques to make model decisions interpretable.
-
Compliance
Ensure your AI systems follow relevant regulations (GDPR, AI Act, etc.).
