Random Forest classification on dense data set like LibSVM without translating the data set into other formats like recordIO. The algorithm scales efficiently across multi-cores on a single AWS EC2 Instance out of the box.
Highlights
Users don't have to translate their csv, tsv dataset into other formats
Leaf-wise tree growth algorithm to achieve lower loss
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.
You pay by the hour for the compute instance you run, with no upfront commitment. Pricing splits into three activities: training a model, running batch inference, and running real-time inference. Each activity is offered across nine AWS instance sizes in the c4 and c5 families. Costs scale with the instance you pick — larger instances carry higher hourly rates. You choose the size based on your data and performance needs. Batch inference processes data in groups, while real-time inference serves predictions on demand. Total cost depends on the instance type, the activity, and the hours used.
Top-of-mind questions for buyers
Am I charged when a training or inference instance is stopped or idle?
You pay per host-hour only while the instance runs. A stopped instance accrues no software charges. The meter counts active running time for the activity and instance type you selected. Underlying AWS storage or related resources may still bill separately through your AWS account.
What does one HostHrs unit represent for billing?
One HostHrs unit is one hour that a single compute instance runs your chosen activity. The activity is training, batch inference, or real-time inference. Each instance type in the c4 and c5 families has its own hourly rate. The clock runs while the instance is active.
How does batch inference billing differ from real-time inference billing?
Both bill per host-hour on the same c4 and c5 instance types. Batch inference runs only while processing a group of data, so you pay for that run window. Real-time inference keeps an endpoint running to serve predictions on demand, so you pay for all hours the endpoint stays up.

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 .
