Abstract
Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for discovering unique entities over multiple devices. A virtual pool of entities is created and divided into subpools, each including fewer than all entities. Subpools are subdivided into delta pools. Cookies are recorded for each delta pool when the particular portion of content is presented to or accessed by entities in the delta pool. Recorded cookies are divided into cookie types based on cookie characteristics. Machine learning and statistical analysis algorithms are used to automatically determine sizes of delta pools and probabilities of each cookie type being classified as belonging to particular delta pools. Virtual entities are assigned from the virtual pool to each of the recorded cookies that were recorded when the particular portion of content was presented. A number of unique entities that accessed the particular portion of content is determined.
