AI / ML Development

The development of artificial intelligence (AI) involves systems that make predictions, classifications, and automate processes based on data provided. Designing, building, training, deploying and maintaining are all essential steps within the Artificial Intelligence and Machine Learning development processes, Learn from data systems and processes. To assist, here’s a structured breakdown on the development of AI/ML that you either are starting from scratch or working on an advanced systems.

AI / ML Development Lifecycle

Problem Definition

Define the objective: classification, regression, clustering, NLP, vision, etc.
Identify performance metrics (accuracy, F1-score, MSE, etc.)

Data Collection & Preparation

Gather structured or unstructured data
Clean and preprocess: handle missing values, normalize, encode
Perform feature engineering
Split data into train/validation/test sets

Model Selection

Classification/Regression: Logistic Regression, Random Forest, XGBoost
NLP: Transformers (BERT, GPT), RNNs
Computer Vision: CNNs, ResNet, YOLO
Unsupervised: k-Means, DBSCAN, PCA
Reinforcement Learning: DQN, PPO

Model Training & Tuning

Train using frameworks like:
- scikit-learn (traditional ML)
- TensorFlow / Keras (deep learning)
- PyTorch (flexible deep learning)

Tune hyperparameters (e.g., grid search, Optuna, Bayesian optimization)
Evaluate with validation data

Model Evaluation

Use cross-validation for robustness
Check for bias/variance, overfitting/underfitting
Use confusion matrix, ROC curve, or regression plots

Deployment

Save model (e.g., joblib, pickle, ONNX, SavedModel)
Serve model via:
Flask or FastAPI (REST API)
Docker (containerization)
Cloud platforms (AWS SageMaker, GCP AI Platform, Azure ML)
Set up A/B testing and canary deployment (if needed)

Monitoring & Maintenance

Track performance in production
Monitor data drift, model degradation
Implement retraining pipelines
Use MLflow or DVC for experiment tracking
