Getting Started with H2O.ai

To begin using H2O.ai, visit the official site: www.h2o.ai and choose the product that fits your needs — either the open-source H2O-3 platform or Driverless AI for enterprise users.

To use H2O-3:

Install via pip (pip install h2o) or download from the site
Launch the H2O server in your local or cloud environment
Access the web UI at localhost:54321 or use it through Python or R notebooks
Upload your dataset and start building models

If you’re using Driverless AI, you’ll have a guided GUI that handles everything from feature engineering to deployment with minimal manual coding.

Using H2O AutoML

AutoML in H2O allows users to train and tune multiple models automatically. After loading a dataset:

Split data into training and test sets
Run the H2OAutoML() function with simple parameters
Review the leaderboard to see which models performed best
Export the best model for production use

AutoML is suitable for classification, regression, and time-series forecasting tasks.

The system also produces feature importance plots and performance metrics for quick evaluation.

Using Driverless AI

Driverless AI is a paid, enterprise solution that adds powerful automation features:

Automatic feature transformation
Model interpretability with SHAP values
GPU acceleration for fast training
Deployment-ready pipelines for production use

You can run it on-premises, on VMs, or in the cloud. It comes with visual workflows, making it ideal for business users and non-programmers looking to get results quickly.

Model Deployment

After training, H2O.ai models can be:

Exported as MOJO (Model Object, Optimized) files
Deployed in Java-based applications
Served via REST APIs
Integrated into Spark or Hadoop environments

H2O provides flexible deployment options to match modern architecture needs.
