Hide about this portal


This portal is to open public enhancement requests against products and services offered by the IBM Data & AI organization. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:


Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,


Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

Feature Store Functionality for computed feature definition

See this idea on ideas.ibm.com

We are looking for a solution that will automate feature management and ensure data consistency between training and inference processing.

We expect Feature Store to enable faster and more reliable deployment of ML models in production environments by:

  1. Eliminating redundant feature creation - computed feature definitions should be shared across models.

  2. Ensuring consistency of computed features across exploration, training and inference - the ability to use the same computed feature definition across these stages.

  3. Optimizing resource utilization - avoiding multiple computations of the same features compared to the current solution, where variables are calculated on the fly at each model processing stage.

  4. Facilitating the management and monitoring of computed variables - a central repository that improves monitoring (e.g. feature stability analysis) and versioning.

As a reference - similar functionalities provided by AWS SageMaker Feature Store and Databricks Feature Store

As an example - we could use avg of SUM_DEPOSITS_EUR_OVERALL in 3 months - that definition is commonly use across different models and different stages of lifecycle of modelling - exploration, training and inference:

Transformation.avg_col(df, DEPOSIT_AVG_BAL_3M, SUM_DEPOSITS_EUR_OVERALL, windows_dict['w3'])
