Patent Document ID: 6134532
Application ID: 08971091

Base Claim:
1. A computerized system for associating an observed behavior with items, comprising: a converter capable of converting the observed behavior to a behavior vector; a profile adapter capable of modifying a profile vector with the behavior vector; and a comparater capable of comparing the modified profile vector to a plurality of entity vectors, the entity vectors indicative of the items, so as to identify at least one entity vector closely associated with the observed behavior.

Claim 7:
7. The computerized system as defined in claim 1, wherein the profile adapter modifies the profile vector based upon at least one parameter selected from the group consisting of: a threshold by which a behavior vector will be used instead of the entity vector, a learning rate for a profile update, a leaning rate for an entity update, an update rate for a query universe estimate of a mean, an update for a profile universe update of a mean, a forgetting factor for a set of profile vectors, a forgetting factor for a set of entity vectors, a mean of a set of entity vectors, a mean of a set profile vectors, and a mean of a set of behavior vectors.
