Abstract: An online system, such as an online content distribution system, receives information describing presentations of a content item. The online system identifies online system users included among individuals presented with the content item, retrieves information describing a household of each user, and de-biases this information to adjust for differences between the population of online system users and the individuals to whom the content item was presented. The online system then trains a set of machine-learning models to infer a reach of the content item for each of multiple households using the de-biased information. Using the machine-learning models, the online system infers a reach of the content item for each of the households.

Abstract: A method for providing content items to one or more client devices associated with at least one unresolved identifier. An unresolved identifier defines a context in which a client device accesses one or more online systems, the context not determined to be associated with a specific user. The method comprises identifying a set of unresolved identifiers, and identifying information describing one or more access events associated with each unresolved identifier. For each pair of unresolved identifiers, a similarity score for the pair is determined based on the identified information. Responsive to the similarity score exceeding a threshold similarity score, the pair of unresolved identifiers is clustered, the clustering indicating a prediction that the pair of unresolved identifiers are associated with a common user. Based on this clustering, a content item is displayed on or more user devices associated with at least one unresolved identifier of the set of unresolved identifiers.
