Counterfactual outcome

As explained in Delivering Machine Learning Projects: From design to deployment

A counterfactual scenario is a hypothetical situation describing how outcomes might change under an altered condition or input.

A counterfactual outcome describes how a prediction might change when users alter model inputs or parameters. It turns a model into a decision-support tool rather than a single fixed forecast. section 8.5

A useful implementation should:

  • Accept user-defined parameters for testing alternative conditions. section 8.5
  • Return a range of possible outcomes, including confidence intervals. section 8.5
  • Offer prebuilt scenarios to support business analysis and decision-making. section 8.5

A user can test a demand prediction under changed geographic, product-type, locale, or platform conditions, then compare the resulting outcome range with prebuilt scenarios. section 8.5

How Delivering Machine Learning Projects: From design to deployment covers it

How deep it goes
Defines parameterized what-if use but stops short of specifying counterfactual inference algorithms or implementation internals.
Examples
Uses altered geographic, product-type, locale, and platform conditions alongside prebuilt scenarios for demand prediction.
What it assumes
Assumes access to a predictive model whose inputs or parameters can be varied by authorized users.
What you can do after
Apply it via parameterized models to compare alternative predictions and inform business decisions.
How it connects
Connects model parameterization with confidence intervals, demand prediction, performance monitoring, and decision-making.
