Technical report TR04-07. Typical association rules consider only items enumerated in transactions. Such rules are referred to as positive association rules. Negative association rules also consider the same items, but in addition consider negated items (i.e. absent from transactions). Negative...

Modeling and Querying Multimedia Data
1998
Technical report TR98-05. Amidst the dramatic developments of computer technology in the last decades, we have seen a growing interest in supporting multimedia data. Compared with traditional data, the most noticeable features of multimedia data are their spatiality (the spatial layout of...

Technical report TR09-01. Finding the top-k values is an important type of aggregation query in wireless sensor networks. Previous proposals relied on a given underlying logical tree topology for data aggregation/forwarding, but did not pay due attention to the role of such topology. In this...

Technical report TR09-15. Sequential decision-making with multiple agents and imperfect information is commonly modeled as an extensive game. One efficient method for computing Nash equilibria in large, zero-sum, imperfect information games is counterfactual regret minimization (CFR). In the...

On the Trade-Off Between User-Location Privacy and Queried-Location Privacy in Wireless Sensor Networks
Download2009
Harms, Janelle, Vogt, Ryan, Nascimento, Mario
Technical report TR09-07. By eavesdropping on a user's query in a sensor network, an adversary can deduce both the user's location and his/her area of interest. In many domains it is desirable to guarantee privacy of both places. Relying on the principle of k-anonymity, we propose an effective...

Technical report TR09-05. It is a well known fact that minimizing energy consumption in Wireless Sensor Networks (WSNs) is crucial for its usability; and minimizing the flow of data is one way to achieve that. Most WSN models assume the existence of a base station where query results could in...

Technical report TR90-33. Object-oriented database systems have been proposed as an effective solution for providing the data management facilities of complex applications. Proving the veracity of this claim and the investigation of related issues such as query processing have been hampered by...

Technical report TR07-14. Extensive games are a powerful model of multiagent decision-making scenarios with incomplete information. Finding a Nash equilibrium for very large instances of these games has received a great deal of recent attention. In this paper, we describe a new technique for...

Technical report TR04-05. Recently, some researchers have argued that generative design patterns (GDPs) can leverage the obvious design re-use that characterizes traditional design patterns into code re-use. This paper provides additional evidence that GDPs are both useful and productive. ...

Technical report TR93-13. Chess endgame databases, while of important theoretical interest, have yet to make a significant impact in tournament chess. In the game of checkers, however, endgame databases have played a pivotal role in the success of our World Championship challenger program...
