h2o-3 is a distributed machine learning platform and automated machine learning framework designed for training and deploying predictive models using distributed in-memory computing. It functions as a deep learning framework and a distributed model scoring engine, capable of operating as a Kubernetes ML cluster to process large datasets in parallel.
The platform distinguishes itself through automated machine learning capabilities that automatically select the best algorithms and hyperparameters to optimize model performance. It provides specialized deep learning toolkits for tasks including image classification, anomaly detection, and image reconstruction and clustering.
The system covers a broad range of capabilities including large-scale data processing via map-reduce and distributed key-value stores, and model explainability analysis to interpret predictions. Its model management suite supports the serialization of trained models into standalone artifacts for high-performance production scoring, alongside a registry for model logging and lifecycle orchestration.
Deployment and orchestration are supported via Kubernetes stateful sets, Hadoop integration, and a web-based management interface.
