Abstract: A toy system includes a drivable surface that includes location encoding markings. A toy vehicle or mobile agent is provided that includes a drive motor, an imaging system for taking images of the markings, a vehicle wireless transceiver, and a microcontroller operatively coupled to the motor, the imaging system, and the vehicle wireless transceiver. A basestation is provided that includes a controller operatively coupled to a basestation wireless transceiver. Via wireless communication between the wireless transceivers of the toy vehicle and the basestation, an action to be implemented by the toy vehicle can be determined by the basestation and communicated to the toy vehicle, whereupon the microcontroller of the toy vehicle controls detailed movement of the toy vehicle on the drivable surface based on images taken of the markings of the drivable surface by the imaging system to cause the toy vehicle to implement the action on the drivable surface.

Abstract: Intrusion features of a landing page associated with sponsored content are identified. A feature score for the landing page based on the identified intrusion features is generated, and if the feature score for the landing page exceeds a feature threshold, the landing page is classified as a candidate landing page. A sponsor account associated with the candidate landing page can be suspended, or sponsored content associated with the candidate landing page can be suspended.

Abstract: Landing pages associated with advertisements are partitioned into training landing pages and testing landing pages. Iterative training and testing of a classification mode on intrusion features of the partitioned landing pages is conducted until the occurrence of a cessation event. Feature weights are derived from the iterative training and testing, and are associated with the intrusion features. The associated feature weights and intrusion features can be used to classify other landing pages.
