    Literature Survey on Various Frequent Pattern Mining Algorithm

    Data mining discovers hidden pattern in data sets and association between the patterns. In this association, rule mining is one of the techniques used to achieve the objective of data mining. These rules are effectively used to uncover unknown relationships producing result that can give the authors a basis for...

    A TMS DSP Processor Based Case Study of Grigoryan FFT Performance Over Cooley-Tukey FFT (TMS320C6748, TMS320C5515)

    Frequency analysis plays vital role in the applications like cryptanalysis, steganalysis, system identification, controller tuning, speech recognition, noise filters, etc. Discrete Fourier Transform (DFT) is a principal mathematical method for the frequency analysis. The way of splitting the DFT gives out various fast algorithms. In this paper, the authors present...

    Dijkstra Algorithm for Feeder Routing of Radial Distribution System

    This paper proposes the application of Dijkstra algorithm for feeder routing of radial distribution system. A complete network of available routes is considered and the optimization goal is to find the routes that provide the minimal total annual cost, which is obtained by the proposed algorithm. Distribution system planning mainly...

    Informative Knowledge Discovery Using Multiple Data Sources, Multiple Features and Multiple Data Mining Techniques

    Data mining is a process of obtaining trends or patterns in historical data. Such trends form business intelligence that in turn leads to taking well informed decisions. However, data mining with a single technique does not yield actionable knowledge. This is because enterprises have huge databases and heterogeneous in nature....

    Sequential Pattern Mining Using Apriori Algorithm & Frequent Pattern Tree Algorithm

    The concept of Sequential Pattern Mining was first introduced by Rakesh Agrawal and Ramakrishnan Srikant in the year 1995. Sequential Patterns are used to discover sequential sub-sequences among large amount of sequential data. In web usage mining, Sequential Patterns are exploited to find sequential navigation patterns that appear in users'...
