1. A system for enhancing performance of a data pattern recognizer for an entity, the system comprising: one or more processors; a memory; a base parameter component that obtains a base set of parameters of the recognizer; a personalization component that updates the recognizer based at least in part upon at least one sample customized to the entity, the personalization component utilizes regularization favoring the base set of parameters of the recognizer during update of the recognizer; a regularization component that utilizes regularization to determine a new set of parameters for the recognizer; and a parameter update component that updates the base set of parameters of the recognizer to the new set of parameters, wherein one or more of the components comprise a set of processor-executable instructions stored in the memory and that, when executed by the one or more processors, perform its described operation.
