Patent number: 7337155Abstract: To deal with user network communication activity which cannot easily and clearly be determined as problematic behavior, a behavior analysis apparatus 14 monitors communication between each user PC 16 in a domain 10 and Internet 20 via a gateway apparatus 12. For example, when there is a monitored item related to information leakage of the user in the detected communication, a weight value corresponding to the monitored item is added to a score concerning a possibility of the user leaking information. Subsequently, the scores are totaled and recorded for each unit of time. The behavior analysis apparatus 14 inputs data of time-series transition of the total value to a neural network which has performed learning for prediction processing, and predicts the possibility of the user's information leak at a time in the near future. When an increasing risk of leakage is predicted, the behavior analysis apparatus 14 communicates an alarm to a security manager.Type: GrantFiled: March 6, 2003Date of Patent: February 26, 2008Assignee: Fuji Xerox Co., Ltd.Inventor: Takeo Yoshida

Patent number: 7310623Abstract: A quantum approach to the economically significant n-player public goods or similar n-player game requires only two-particle entanglement and is thus much easier to implement than games requiring n-particle entanglements. Two-particle entanglements are sufficient to give near optimal expected payoff when players use a simple mixed strategy for which no player can benefit by making different choices. This mechanism can also address some heterogeneous preferences among the players. Quantum games in accordance with the invention can be simulated on classical computers without requiring impractical amounts of processing power for large numbers of players.Type: GrantFiled: December 12, 2003Date of Patent: December 18, 2007Assignee: Hewlett-Packard Development Company, L.P.Inventors: Raymond G.

Patent number: 7280988Abstract: A monitoring system including a baseline model that automatically captures and models normal system behavior, a correlation model that employs multivariate autoregression analysis to detect abnormal system behavior, and an alarm service that weights and scores a variety of alerts to determine an alarm status and implement appropriate response actions. The baseline model decomposes the input variables into a number of components representing relatively predictable behaviors so that the erratic component e(t) may be isolated for further processing. These components include a global trend component, a cyclical component, and a seasonal component. Modeling and continually updating these components separately permits a more accurate identification of the erratic component of the input variable, which typically reflects abnormal patterns when they occur.Type: GrantFiled: December 19, 2002Date of Patent: October 9, 2007Assignee: Netuitive, Inc.Inventors: David Helsper, Jean-Francois Huard, David Homoki, Amanda Rasmussen, Robert Jannarone

Patent number: 7280987Abstract: A system and method for generating a neural network ensemble. Conventional algorithms are used to train a number of neural networks having error diversity, for example by having a different number of hidden nodes in each network.
