Update to REDP-5661-00 - Optimized Inferencing and Integration with AI Platforms on IBM Z

An IBM Redbooks residency (ZS-CM09-R01)


The goal of this residency is to update REDP-5661-00, Optimized Inferencing and Integration with AI on IBM Z: Introduction, Methodology, and Use Cases. The update will include: Updates to the credit risk scoring on IBM Z use case to discuss the full product of WMLz V2.4 in further detail, highlighting the batching capability it provides and the value add it brings when compared to WMLz OSCE when AIU is present, highlight the CICS Cobol Scoring service from COBOL language programs, and describe and demonstrate the steps to modify the implementation to leverage AIU. It will also imclude the addition of a new chapter that discusses and demonstrates the implementation and integration of an end-to-end solution leveraging Deep Learning models to enforce a Payments Fraud Detection use case, based on an internal demo, and discuss the benefits derived from the solution, focusing on the value derrived from leveraging AIU and IBM Z.

    Benefits to Resident

    IBM Redbooks want technical practitioners to be recognized for their newly gained knowledge, experience, and accomplishments. Therefore, upon successful delivery of the publication produced by this IBM Redbooks residency, you will become eligible to earn an IBM Redbooks Digital Badge issued through Credly.


    Update credit risk scoring use case:

    • Document the benefits received from leveraging the full WMLz product versus WMLz OSCE when the z16 on-chip AI accelerator is present, highlighting the batching capability and CICS COBOL Scoring service from COBOL language programs.

    • Describe the steps to modify the implementation to leverage AIU.

    Add a new chapter discussing a Payments use case on IBM Z that targets bank account to bank account transfer payments fraud (based on an internal banking showcase demo):

    • Discuss the business value of the solution with a focus on the unique benefits provided by Z.

    • Provide examples of industry scenarios that can leverage the solution.
    • Describe the use case.
    • Illustrate and describe reference architecture for the solution and how the pieces of the solution fit together and how the software components take benefit of the on-chip AI acceleration.
    • Describe the data science process of understanding and preparing the data for the model.
    • Describe the process of (Long Short-Term) model development and training.
    • Describe the process of (Long Short-Term) Model deployment and evaluation on IBM Z.
    • Describe and illustrate the process of using a JavaScript user interface to simulate a payment request with or without volume, invoking the model for inferencing, and using a dashboard to view insights derrived from the inference process on scored payments and engine performances.

    *Residents will be responsible for verifying the system environment setup and applying any updates, reconfigurations, or configuring new software to enable the implementation.
