Prosper Insights & Analytics' propensity model predicts the probability that a U.S. adult consumer plans to buy Flowers for Valentine’s Day. Based on a set of basic demographics, the model identifies individuals who are likely to be Flower Buyers. The model was trained with data from Prosper's large database of U.S. adult consumer intentions and actions (N=7,267)
Highlights
Enhances digital and offline targeting by identifying individuals likely to buy Flowers for Valentine's Day
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 for running this propensity model on your chosen instance. Pricing is usage-based, so you are billed only for the compute time you use. The dimensions fall into two groups: batch inference, which scores large data sets in scheduled runs, and real-time inference, which returns scores on demand. Within each group, you select an instance type from the ml.m4, ml.m5, ml.c4, ml.c5, ml.p2, and ml.p3 families. Larger instances add compute and memory capacity, so hourly cost scales with the size and power of the instance you pick.
Top-of-mind questions for buyers
What does one HostHrs unit cover for billing?
One HostHrs unit is one hour that a single instance runs your inference job. Billing counts each active host by the hour. If you run several instances at once, each one meters its own hours. Partial hours follow standard AWS metering for the instance type you select.
What is the difference between batch and real-time inference charges?
Batch inference scores large data sets in scheduled runs, so charges accrue only while a run processes. Real-time inference keeps an endpoint running to score requests on demand, so charges accrue for every hour the endpoint stays active, whether or not requests arrive.
Am I charged when a real-time endpoint sits idle with no requests?
Yes. Real-time inference bills per host hour while the endpoint stays running, even during idle periods with no scoring requests. To stop charges, you shut the endpoint down. Batch jobs only accrue hours during active processing, so idle time does not apply the same way.

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 .

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.
