AI governance tutorial: Build and deploy a model

AI governance tutorial: Build and deploy a model

This tutorial is the first in a series of two tutorials. Take this tutorial to build, deploy, and track a model with the AI governance use case. Your goal is to train a model to predict which applicants qualify for mortgages and then deploy the model for evaluation. You must also set up tracking for the model to document the model history and generate an explanation for its performance.

Quick start: If you did not already create the sample project for this tutorial, access the AI governance sample project in the Resource hub.

The story for the tutorial is that Golden Bank wants to expand its business by offering low-rate mortgage renewals for online applications. Online applications expand the bank’s customer reach and reduce the bank’s application processing costs. As a data scientist at Golden Bank, you must create a mortgage approval model that avoids unanticipated risk and treats all applicants fairly. You will run a Jupyter Notebook to build a model and automatically capture metadata that tracks the model in an AI Factsheet.

The following animated image provides a quick preview of what you’ll accomplish by the end of the second tutorial where you will use Watson OpenScale to configure and evaluate monitors for the deployed model to ensure that the model is accurate and treating all applicants fairly.
