Abstract: An online system logs information describing presentation of content items, such as actions performed with presented content items or descriptions of presentation of content items, and uses the logged information to recommend other content items. Because of a large amount of information describing content item presentation, the online system samples the information and stores the resulting samples. To improve accuracy of the sampling, the online system adapts the sampling rate for different types of information describing presentation of content items based on amounts of the different types of information received during a specific time interval.
