Prosper Insights & Analytics' propensity model predicts the probability that a U.S. adult consumer has a specific health condition. Based on a set of basic demographics, the model identifies individuals who are likely to have the health condition. The model was trained with data from Prosper's large Media Behaviors & Influence (MBI) study (N=16,619).
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 host hour, based on the machine learning instance you run for model inference. Pricing splits along two lines. First, choose an inference mode: batch, which scores data in bulk jobs, or real-time, which scores requests as they arrive. Second, choose an instance size, from ml.m4.xlarge up through ml.m5.24xlarge. Larger instances carry more compute and bill at a higher hourly rate. Each mode is offered across the same instance sizes, so you match the compute to your workload. You are charged only for the hours you use.
Top-of-mind questions for buyers
What does one host hour actually count for billing on this product?
One host hour is one hour that a single machine learning instance runs your inference job. Billing meters running time, not the number of records scored. If you run one instance for three hours, you pay three host hours. Two instances running one hour also equals two host hours.
How does batch inference billing differ from real-time inference billing?
Batch mode runs bulk scoring jobs, so you pay host hours only while the job runs, then the instance shuts down. Real-time mode keeps an instance running to answer requests as they arrive, so host hours accrue for the whole time the endpoint stays active, even when idle.
Am I charged when a real-time inference endpoint sits idle between requests?
Yes. Real-time mode bills per host hour while the endpoint stays running, whether or not requests arrive. To stop charges, you shut the endpoint down. Batch jobs avoid idle time because the instance runs only for the duration of the scoring job.

An Amazon SageMaker model package is a pre-trained machine learning model ready to use without additional training. Use the model package to create a 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:
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 .

Inputs
Summary
The model provides propensity estimates based on gender, age range, income range, and zip code. See the sample notebook for details concerning input variables and mappings.
Five digit zip code as integer.
The model requires that the zip code be replaced by a set of 25 binary variables that represent special information regarding the zip. Prosper provides a file that maps every zip code into two integer values (division and cluster). These values are then converted into a set of binary values in a manner similar to one-hot encoding. The mapping file as well as the conversion routines are provided with the sample notebook.
