Clustering

聚簇是為了提高某個屬性(或屬性組)的查詢速度,把這個或這些屬性(稱為聚簇碼)上具有相同值的元組集中存放在連續的物理塊。

  • An Efficient and Effective Detailed Placement Algorithm Global Swap  To identify a pair

    An Efficient and Effective Detailed Placement Algorithm Global Swap  To identify a pair of cells that can be swapped to reduce wirelength (others are fixed). 2. Vertical Swap  Swap a cell with a nearby cell in the segment above or below. 3. Local Re-ordering  Re-order consecutive cells locally to reduce wirelength. 4. Single-Segment Clustering  Place cells optimally within a segment.

  • Recent advances in experimental methods have resulted in the generation of enormous volumes of data

    Recent advances in experimental methods have resulted in the generation of enormous volumes of data across the life sciences. Hence Clustering and classification techniques that were once predominantly the domain of ecologists are now being used more widely. This book provides an overview of these important data analysis methods, from long-established statistical methods to more recent machine learning techniques. It aims to provide a framework that will enable the reader to recognise the assumptions and constraints that are implicit in all such techniques. Important generic issues are discussed first and then the major families of algorithms are described. Throughout the focus is on explanation and understanding and readers are directed to other resources that provide additional mathematical rigour when it is required. Examples taken from across the whole of biology, including bioinformatics, are provided throughout the book to illustrate the key concepts and each technique’s potential.

    Many of the pattern fi nding algorithms such as decision tree, classifi cation rules and Clustering techniques that are frequently used in data mining have been developed in machine learning research community. Frequent pattern and association rule mining is one of the few excep- tions to this tradition. The introduction of this technique boosted data mining research and its impact is tremendous. The algorithm is quite simple and easy to implement. Experimenting with Apriori-like algorithm is the fi rst thing that data miners try to do.

    Quartz is a full-featured, open source job scheduling system that can be integrated with, or used along side virtually any J2EE or J2SE application - from the smallest stand-alone application to the largest e-commerce system. Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs jobs whose tasks are defined as standard Java components or EJBs. The Quartz Scheduler includes many enterprise-class features, such as JTA transactions and Clustering.
