H2O’s Deep Learning is based on a multi-layer feedforward artificial neural network that is trained with stochastic gradient descent using back-propagation. The network can contain a large number of hidden layers consisting of neurons with tanh, rectifier, and maxout activation functions. Advanced features such as adaptive learning rate, rate annealing, momentum training, dropout, L1 or L2 regularization, checkpointing, and grid search enable high predictive accuracy.
Highlights
A feedforward artificial neural network (ANN) model, also known as deep neural network (DNN) or multi-layer perceptron (MLP), is the most common type of Deep Neural Network and the only type that is supported natively in H2O-3.

This algorithm software carries no license fee, so you pay only the hourly infrastructure charge for the compute instance you run. Pricing splits into three activity types: training, batch inference, and real-time inference. Within each type, you choose from the c5, c4, m5, and m4 instance families in sizes ranging from xlarge up to 24xlarge. Larger instances offer more compute and bill at a higher hourly rate. You are charged per host hour (HostHrs) for the instance you select, matching the workload and instance size to your needs.
Top-of-mind questions for buyers
What does one HostHrs unit cover, and how is it counted?
One HostHrs unit is one hour that a single compute instance runs your workload. You are billed for each instance you launch, per hour it stays active. A stopped instance stops accruing software host-hour charges. Underlying AWS infrastructure fees may still apply based on standard AWS terms.
What is the difference between batch inference and real-time inference billing?
Both meter per host hour on the instance you select. Batch inference runs predictions on stored datasets in scheduled jobs, so you pay only while the batch job runs. Real-time inference keeps an endpoint running to serve live requests, so charges accrue for the whole time the endpoint stays active.
Does running a larger instance change how I am billed?
Billing stays per host hour regardless of instance size. Larger instances in the c5, c4, m5, and m4 families bill at a higher hourly rate but on the same unit. You choose one instance per job, so your cost equals its hourly rate times the hours it runs.

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 .
