They must also automate the model retraining to optimize model performance.


To implement Data Science and MLOps for your enterprise, your organization can follow this process:

  1. Prepare and share the data
  2. Build and train models
  3. Deploy models
  4. Monitor deployed models
  5. Automate the AI lifecycle

The Watson Studio, Watson Machine Learning, Watson OpenScale, and IBM Knowledge Catalog services in Cloud Pak for Data as a Service provide the tools and processes that your organization needs to implement a Data Science and MLOps solution.

1. Prepare and share the data

Data scientists can prepare their own data sets and share them in a catalog. The catalog serves as a feature store where your data scientist teams can find high-quality data assets with the features that they need. They can add data assets from a catalog into a project, where they collaborate to prepare, analyze, and model the data.

What you can use What you can do Best to use when
Data Refinery Access and refine data from diverse data source connections.

Materialize the resulting data sets as snapshots in time that might combine, join, or filter data for other data scientists to analyze and explore.

Make the resulting data sets available in catalogs.
You need to visualize the data when you want to shape or cleanse it.

You want to simplify the process of preparing large amounts of raw data for analysis.
Catalogs Use catalogs in IBM Knowledge Catalog as a feature store to organize your assets to share among the collaborators in your organization.

Take advantage of AI-powered semantic search and recommendations to help users find what they need.
Your users need to easily understand, collaborate, enrich, and access the high-quality data.

You want to increase visibility of data and collaboration between business users.

You need users to view, access, manipulate, and analyze data without understanding its physical format or location, and without having to move or copy it.

You want users to enhance assets by rating and reviewing them.

Example: Golden Bank's catalog

The governance team leader creates a catalog, "Mortgage Approval Catalog" and adds the data stewards and data scientists as catalog collaborators. The data stewards publish the data assets that they created into the catalog. The data scientists find the data assets, curated by the data stewards, in the catalog and copy those assets to a project. In their project, the data scientists can refine the data to prepare it for training a model.

2. Build and train models

To get predictive insights based on your data, data scientists, business analysts, and machine learning engineers can build and train models. Data scientists use Cloud Pak for Data as a Service services to build the AI models, ensuring that the right algorithms and optimizations are used to make predictions that help to solve business problems.

What you can use What you can do Best to use when
AutoAI Use AutoAI in Watson Studio to automatically select algorithms, engineer features, generate pipeline candidates, and train model pipeline candidates.

Then, evaluate the ranked pipelines and save the best as models.

Deploy the trained models to a space, or export the model training pipeline that you like from AutoAI into a notebook to refine it.
You want an advanced and automated way to build a good set of training pipelines and models quickly.

You want to be able to export the generated pipelines to refine them.
Notebooks and scripts Use notebooks and scripts in Watson Studio to write your own feature engineering model training and evaluation code in Python or R. Use training data sets that are available in the project, or connections to data sources such as databases, data lakes, or object storage.

Code with your favorite open source frameworks and libraries.
You want to use Python or R coding skills to have full control over the code that is used to create, train, and evaluate the models.
SPSS Modeler flows Use SPSS Modeler flows in Watson Studio to create your own model training, evaluation, and scoring flows. Use training data sets that are available in the project, or connections to data sources such as databases, data lakes, or object storage. You want a simple way to explore data and define model training, evaluation, and scoring flows.
RStudio Analyze data and build and test models by working with R in RStudio. You want to use a development environment to work in R.
Decision Optimization Prepare data, import models, solve problems and compare scenarios, visualize data, find solutions, produce reports, and save models to deploy with Watson Machine Learning. You need to evaluate millions of possibilities to find the best solution to a prescriptive analytics problem.
Federated learning Train a common model that uses distributed data. You need to train a model without moving, combining, or sharing data that is distributed across multiple locations.

Example: Golden Bank's model building and training

Data scientists at Golden Bank create a model, "Mortgage Approval Model" that avoids unanticipated risk and treats all applicants fairly. They want to track the history and performance of the model from the beginning, so they add a model use case to the "Mortgage Approval Catalog". They run a notebook to build the model and predict which applicants qualify for mortgages. The details of the model training are automatically captured as metadata in the model use case.

3. Deploy models

When operations team members deploy your AI models, the models become available for applications to use for scoring and predictions to help drive actions.

What you can use What you can do Best to use when
Spaces user interface Use the Spaces UI to deploy models and other assets from projects to spaces. You want to deploy models and view deployment information in a collaborative workspace.

Example: Golden Bank's model deployment

The operations team members at Golden Bank promote the "Mortgage Approval Model" from the project to a deployment space and then creates an online model deployment.

4. Monitor deployed models

After models are deployed, it is important to monitor them to make sure that they are performing well. Data scientists must watch for model performance and data consistency issues.

What you can use What you can do Best to use when
Watson OpenScale Monitor model fairness issues across multiple features.

Monitor model performance and data consistency over time.

Explain how the model arrived at certain predictions with weighted factors.

Maintain and report on model governance and lifecycle across your organization.
You have features that are protected or that might contribute to prediction fairness.

You want to trace model performance and data consistencies over time.

You want to know why the model gives certain predictions.

Example: Golden Bank's model monitoring

Data scientists at Golden Bank use Watson OpenScale to monitor the deployed "Mortgage Approval Model" to ensure that it is accurate and treating all Golden Bank mortgage applicants fairly. They run a notebook to set up monitors for the model and then tweak the configuration by using the Watson OpenScale user interface. Using metrics from the Watson OpenScale quality monitor and fairness monitor, the data scientists determine how well the model predicts outcomes and if it produces any biased outcomes. They also get insights for how the model comes to decisions so that the decisions can be explained to the mortgage applicants.

5. Automate the AI lifecycle

Your team can automate and simplify the MLOps and AI lifecycle with Orchestration Pipelines.

What you can use What you can do Best to use when
Orchestration Pipelines Use pipelines to create repeatable and scheduled flows that automate notebook, Data Refinery, and machine learning pipelines, from data ingestion to model training, testing, and deployment. You want to automate some or all of the steps in an MLOps flow.

Example: Golden Bank's automated ML lifecycle

The data scientists at Golden Bank can use pipelines to automate their complete Data Science and MLOps lifecycle and processes to simplify the model retraining process.
