Competence-Preserving Case-Deletion Strategy for Case Base . . .

by Mohamed Karim Haouchine, Brigitte Chebel-morello, Noureddine Zerhouni - ECCBR'08, TRIER: GERMANY , 2008
"... The main goal of a Case-Based Reasoning (CBR) system is to provide criteria for evaluating the internal behavior and task efficiency of a particular system for a given initial case base and sequence of a solved problems. The choice of Case Base Maintenance (CBM) strategies is driven by the maintai ..."

by the maintainer's performance goals for the system and by constraints on the system's design and the task environment. This paper gives an overview of CBM works and proposes a case deletion strategy based on a competence criterion using a novel approach. The proposed method combines an algorithm with a

Processing Set Expressions over Continuous Update Streams

by Sumit Ganguly, Minos Garofalakis, Rajeev Rastogi , 2003
"... There is growing interest in algorithms for processing and querying continuous data streams (i.e., data that is seen only once in a fixed order) with limited memory resources. In its most general form, a data stream is actually an update stream, i.e., comprising data-item deletions as well as insert ..."

Hybrid Deletion Policies for Case Base Maintenance

by Maria Salamó , Elisabet Golobardes Enginyeria , La Arquitectura , Salle - In Proc. of the sixteenth International FLAIRS Conference , 2003
"... Abstract. Case memory maintenance in a Case-Based Reasoning system is important for two main reasons: (1) to control the case memory size; (2) to reduce irrelevant and redundant instances that may produce noise in the Case-Based Reasoning system. In this paper we present two approaches based on del ..."

on deletion policies to the maintenance of case memories. The foundations of both approaches are the Rough Sets Theory, but each one applies a different policy to delete or maintain cases. The main purpose of these methods is to maintain the competence of the system and reduce, as much as possible, the size

Efficient Video Streaming using TCP

by Puneet Mehra
"... While most of the traffic on the Internet today consists of TCP flows, conventional wisdom holds that TCP is unsuitable for video streaming applications due to its insistence on reliability and lack of throughput guarantees. However, most streaming protocols need to implement many features of TCP in ..."

), and therefore may not provide streaming applications with the necessary bit-rate. In our prior work, we outlined a receiver-based bandwidth sharing system (BWSS) for allocating the capacity of last mile bottlenecks among TCP flows according to a user’s preferences. This system does not require modifications

D.: Adaptation-guided case base maintenance

by Vahid Jalali, David Leake - In: Proceedings of the Twenty-Eighth Conference on Artificial Intelligence, AAAI Press (2014) In
"... In case-based reasoning (CBR), problems are solved by retrieving prior cases and adapting their solutions to fit; learning occurs as new cases are stored. Control-ling the growth of the case base is a fundamental prob-lem, and research on case-base maintenance has devel-oped methods for compacting c ..."

case bases while main-taining system competence, primarily by competence-based deletion strategies assuming static case adapta-tion knowledge. This paper proposes adaptation-guided case-base maintenance (AGCBM), a case-base main-tenance approach exploiting the ability to dynamically generate new

CASE Design Maintenance

by Lditional Maintenance Has
"... proven difficult in the absence of design information [19]; maintainers often spend considerable energy trying to recover this design information before making changes [15]. Capture and reuse of certain kinds of design informa-tion should consequently improve the maintenance process. Updating the de ..."

. If one had a design maintenance system based on integrating formal deltas, then the life cycle notions of design/coding phases and mainte-nance phases become indistinguish-able. Software would be con-structed by incrementally revising a current design according to a con-tinuous stream of maintenance del

On BiasedReservoir Samplingin the Presence of Stream Evolution

by unknown authors
"... The method of reservoir based sampling is often used to pick an unbiased sample from a data stream. A large portion of the unbiased sample may become less relevant over time because of evolution. An analytical or mining task (eg. query estimation) which is specific to only the sample points from a r ..."

Informed case base maintenance: A complexity profiling approach

by Susan Craw, Stewart Massie, Nirmalie Wiratunga , 2007
"... Knowledge maintenance for Case-Based Reasoning systems is an important knowledge engineering task despite the avail-ability of initial case knowledge and new cases to extend it. For classification systems it is essential that different sce-narios for the various classes are well represented and de-c ..."

Tcp-Based Video Streaming Using Receiver-Driven Bandwidth Sharing
