PC Cluster Based Parallel Frequent Pattern Mining and Parallel Web Access Pattern MiningC cluster are also becoming widely available. Modern algorithms for frequent pattern mining employs complicated tree structure. Here we report the development of the tree based parallel mining algorithms on PC cluster: Parallel FP-growth and an extension to mine web access patterns called Parallel W

An Improved Optimistic and Fault-Tolerant Replication Protocol approach reduces the abortion rates, and improves the performance of the system. It can also use a dynamic computation of the protocol threshold, approximating its results to the optimal ones. In addition, fault tolerance has been included in the algorithm, using a pseudo-optimistic approach, and a

Vectorization of Graphical Components in Sketch-Based Interfaceses not require specialized knowledge or precision. A picture can contain characters, symbols and graphical components. Usually, the recognition of graphical components and their vectorization follows the text and symbols detection phase in pattern recognition algorithms. This paper presents an algor
