Reinforcement learning: a survey

by Leslie Pack Kaelbling, Michael L. Littman, Andrew W. Moore - Journal of Artificial Intelligence Research , 1996
"... This paper surveys the field of reinforcement learning from a computer-science perspective. It is written to be accessible to researchers familiar with machine learning. Both the historical basis of the field and a broad selection of current work are summarized. Reinforcement learning is the problem ..."

Query evaluation techniques for large databases

by Goetz Graefe - ACM COMPUTING SURVEYS , 1993
"... Database management systems will continue to manage large data volumes. Thus, efficient algorithms for accessing and manipulating large sets and sequences will be required to provide acceptable performance. The advent of object-oriented and extensible database systems will not solve this problem. On ..."

. On the contrary, modern data models exacerbate it: In order to manipulate large sets of complex objects as efficiently as today’s database systems manipulate simple records, query processing algorithms and software will become more complex, and a solid understanding of algorithm and architectural issues

Practical Byzantine fault tolerance and proactive recovery

by Miguel Castro, Barbara Liskov - ACM Transactions on Computer Systems , 2002
"... Our growing reliance on online services accessible on the Internet demands highly available systems that provide correct service without interruptions. Software bugs, operator mistakes, and malicious attacks are a major cause of service interruptions and they can cause arbitrary behavior, that is, B ..."

Survey of clustering data mining techniques

by Pavel Berkhin , 2002
"... Accrue Software, Inc. Clustering is a division of data into groups of similar objects. Representing the data by fewer clusters necessarily loses certain fine details, but achieves simplification. It models data by its clusters. Data modeling puts clustering in a historical perspective rooted in math ..."

Pizza into Java: Translating theory into practice

by Martin Odersky, Philip Wadler - In Proc. 24th ACM Symposium on Principles of Programming Languages , 1997
"... Pizza is a strict superset of Java that incorporates three ideas from the academic community: parametric polymorphism, higher-order functions, and algebraic data types. Pizza attempts to make these ideas accessible by translating them into Java. We mean that both figuratively and literally, because ..."

Software Protection and Simulation on Oblivious RAMs

by Oded Goldreich, Rafail Ostrovsky , 1993
"... Software protection is one of the most important issues concerning computer practice. There exist many heuristics and ad-hoc methods for protection, but the problem as a whole has not received the theoretical treatment it deserves. In this paper we provide theoretical treatment of software protectio ..."

Gaia: A Middleware Infrastructure to Enable Active Spaces

by Manuel Román, Christopher Hess, Renato Cerqueira, Roy H. Campbell, Klara Nahrstedt - IEEE Pervasive Computing , 2002
"... We envision a future where people’s living spaces are interactive and programmable. Users interact with their offices, homes, cars, malls and airports to request information, benefit from the resources available, and configure the habitat’s behavior. Data and tasks are always accessible and are mapp ..."

Experiences with a High-Speed Network Adaptor: A Software Perspective

by Peter Druschel, Larry L. Peterson, Bruce S. Davie , 1994
"... This paper describes our experiences, from a software perspective, with the OSIRIS network adaptor. It first identifies the problems we encountered while programming OSIRIS and optimizing network performance, and outlines how we either addressed them in the software, or had to modify the hardware. I ..."

Taint-enhanced policy enforcement: A practical approach to defeat a wide range of attacks

by Wei Xu, Sandeep Bhatkar, R. Sekar - In the Proc. of the 15th USENIX Security Symp , 2006
"... Policy-based confinement, employed in SELinux and specification-based intrusion detection systems, is a popular approach for defending against exploitation of vulnerabilities in benign software. Conventional access control policies employed in these approaches are effective in detecting privilege es ..."

A Practical Dynamic Buffer Overflow Detector

by Olatunji Ruwase, Monica S. Lam - In Proceedings of the 11th Annual Network and Distributed System Security Symposium , 2004
"... Despite previous efforts in auditing software manually and automatically, buffer overruns are still being discovered in programs in use. A dynamic bounds checker detects buffer overruns in erroneous software before it occurs and thereby prevents attacks from corrupting the integrity of the system. D ..."
