Use cases for counterfactual thinking include recommender systems, historical analysis and explainable AI. The key challenge is the counterfactual nature: in the case of Web search, any change to a component of the search engine may result in a different search result page for the same query, but we normally cannot infer reliably from search log how users would react to the new result page.

The counterfactual analysis uses the individual-level parameter estimates and creates an agent-based simulation of the Airbnb market. Given two black-box models, if the counterfactuals across classes are farther away from the input instances on average for one network as compared to the other network, that network would be harder to fool. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. However, when the counterfactuals posed are too far from the data .
