A Sense of Self for Unix Processes

by Stephanie Forrest, Steven A. Hofmeyr, Anil Somayaji, Thomas A. Longstaff - In Proceedings of the 1996 IEEE Symposium on Security and Privacy , 1996
"... A method for anomaly detection is introduced in which "normal" is defined by short-range correlations in a process ' system calls. Initial experiments suggest that the definition is stable during normal behavior for standard UNIX programs. Further, it is able to detect several common ..."

. An important prerequisite of such a system is an appropriate definition of self, which is the subject of this paper. W...

Entity Authentication and Key Distribution

by Mihir Bellare, Phillip Rogaway , 1993
"... Entity authentication and key distribution are central cryptographic problems in distributed computing -- but up until now, they have lacked even a meaningful definition. One consequence is that incorrect and inefficient protocols have proliferated. This paper provides the first treatment of these p ..."

Cost-Aware WWW Proxy Caching Algorithms

by Pei Cao, Sandy Irani - IN PROCEEDINGS OF THE 1997 USENIX SYMPOSIUM ON INTERNET TECHNOLOGY AND SYSTEMS , 1997
"... Web caches can not only reduce network traffic and downloading latency, but can also affect the distribution of web traffic over the network through costaware caching. This paper introduces GreedyDualSize, which incorporates locality with cost and size concerns in a simple and non-parameterized fash ..."

-parameterized fashion for high performance. Trace-driven simulations show that with the appropriate cost definition, GreedyDual-Size outperforms existing web cache replacement algorithms in many aspects, including hit ratios, latency reduction and network cost reduction. In addition, GreedyDual-Size can potentially

Understanding and Using Context

by Anind K. Dey - Personal and Ubiquitous Computing , 2001
"... Context is a poorly used source of information in our computing environments. As a result, we have an impoverished understanding of what context is and how it can be used. In this paper, we provide an operational definition of context and discuss the different ways that context can be used by contex ..."

Ptolemy: A Framework for Simulating and Prototyping Heterogeneous Systems

by Joseph Buck, Soonhoi Ha, Edward A. Lee, David G. Messerschmitt , 1992
"... Ptolemy is an environment for simulation and prototyping of heterogeneous systems. It uses modern object-oriented software technology (C++) to model each subsystem in a natural and efficient manner, and to integrate these subsystems into a whole. Ptolemy encompasses practically all aspects of design ..."
Abstract - Cited by 571 (89 self) - Add to MetaCart
. The core of Ptolemy is a set of object-oriented class definitions that makes few assumptions about the system to be modeled; rather, standard interfaces are provided for generic objects and more specialized, application-specific objects are derived from these. A basic abstraction in Ptolemy is the Domain

Understanding Code Mobility

by Alfonso Fuggetta, Gian Pietro Picco, Giovanni Vigna - IEEE COMPUTER SCIENCE PRESS , 1998
"... The technologies, architectures, and methodologies traditionally used to develop distributed applications exhibit a variety of limitations and drawbacks when applied to large scale distributed settings (e.g., the Internet). In particular, they fail in providing the desired degree of configurability, ..."

approaches. In turn, this limits our ability to fully exploit them in practice, and to further promote the research work on mobile code. Indeed, a significant symptom of this situation is the lack of a commonly accepted and sound definition of the term "mobile code" itself. This paper presents a

Computational Interpretations of the Gricean Maxims in the Generation of Referring Expressions

by Robert Dale, Ehud Reiter - COGNITIVE SCIENCE , 1995
"... We examine the problem of generating definite noun phrases that are appropriate referring expressions: that is, noun phrases that (a) successfully identify the intended referent to the hearer whilst (b) not conveying to him or her any false conversational implicatures (Grice, 1975). We review severa ..."

1 ENVIRONMENTAL RESOURCES TRUST Pioneering Markets to Improve the Environment Renewable Energy Certificates and Air Emissions Benefits Developing an Appropriate Definition for a REC

by Patrick Leahy, Alden Hathaway , 2004
"... The past few years have witnessed the emergence of the Renewable Energy Certificate (REC) market as a viable model for the U.S. renewable energy industry. Once considered an esoteric topic for even the most ardent renewable energy expert, RECs have grown in popularity and exposure thanks to efforts ..."
Abstract - Add to MetaCart
growth, a broad spectrum of market participants are revisiting some basic questions surrounding the definition of a REC, i.e. “What exactly is a REC? And what is its impact on air emissions? ” As the market continues to mature, it will become increasingly important to answer these types of questions

A semantic concordance

by George A. Miller, Claudia Leacock, Ee Tengi, Ross T. Bunker - Proceedings ARPA Human Language Technology Workshop , 1993
"... A semantic concordance is a textual corpus and a lexicon So combined that every substantive word in the text is linked to its appropriate ~nse in the lexicon. Thus it can be viewed either as a corpus in which words have been tagged syntactically and semantically, or as a lexicon in which example sen ..."

Correlation-based feature selection for machine learning

by Mark A. Hall , 1998
"... A central problem in machine learning is identifying a representative set of features from which to construct a classification model for a particular task. This thesis addresses the problem of feature selection for machine learning through a correlation based approach. The central hypothesis is that ..."
Abstract - Cited by 318 (3 self) - Add to MetaCart
is that good feature sets contain features that are highly correlated with the class, yet uncorrelated with each other. A feature evaluation formula, based on ideas from test theory, provides an operational definition of this hypothesis. CFS (Correlation based Feature Selection) is an algorithm that couples
