Gradient Boosting Machine (for Regression and Classification) is a forward learning ensemble method. The guiding heuristic is that good predictive results can be obtained through increasingly refined approximations. H2O’s GBM sequentially builds regression trees on all the features of the dataset in a fully distributed way - each tree is built in parallel.
Highlights
H2O’s Gradient Boosting Algorithms follow the algorithm specified by Hastie et al (2001)

AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
This algorithm is offered free, so you pay only for the AWS compute hours it runs on. Pricing is organized by three activities: training your model, batch inference, and real-time inference. Within each activity, you choose an instance type from the c4, c5, m4, and m5 families. Larger instance sizes offer more compute and carry higher hourly rates. You are billed per host hour for the instance you select. Match the activity and instance size to your workload to control cost.
Top-of-mind questions for buyers
What does one host hour mean for billing on this algorithm?
One host hour is one running hour of the AWS instance you select. Since the algorithm itself is free, you pay only the AWS compute charge for that instance while it runs. Billing accrues per hour that the instance is active for training or inference.
How do the batch inference and real-time inference charges differ?
Both meter per host hour on the instance you choose. Batch mode runs inference on a dataset in scheduled jobs, so you pay only while the job runs. Real-time mode keeps an endpoint hosted, so charges accrue for the whole time the endpoint stays active.
Am I charged when an instance is stopped or the job finishes?
Charges apply per host hour only while the instance runs. When a batch job completes or you stop a real-time endpoint, software metering ends. A stopped instance may still incur underlying AWS storage fees, but the host-hour charge meters running time only.

An Amazon SageMaker algorithm is a machine learning model that requires your training data to make predictions. Use the included training algorithm to generate your unique model artifact. Then deploy the model on Amazon SageMaker for real-time inference or batch processing. Amazon SageMaker is a fully managed platform for building, training, and deploying machine learning models at scale.
Deploy the model on Amazon SageMaker AI using the following options:
Algorithm training
Before deploying the model, train it with your data using the algorithm training process. You're billed for software and SageMaker infrastructure costs only during training. Duration depends on the algorithm, instance type, and training data size. When training completes, the model artifacts save to your Amazon S3 bucket. These artifacts load into the model when you deploy for real-time inference or batch processing. For more information, see Use an Algorithm to Run a Training Job .
Real-time inference
Deploy the model as an API endpoint for your applications. When you send data to the endpoint, SageMaker processes it and returns results by API response. The endpoint runs continuously until you delete it. You're billed for software and SageMaker infrastructure costs while the endpoint runs. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Deploy models for real-time inference .
Batch transform
Deploy the model to process batches of data stored in Amazon Simple Storage Service (Amazon S3). SageMaker runs the job, processes your data, and returns results to Amazon S3. When complete, SageMaker stops the model. You're billed for software and SageMaker infrastructure costs only during the batch job. Duration depends on your model, instance type, and dataset size. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Batch transform for inference with Amazon SageMaker AI .
