• Initialization of Self-Organizing Maps: Principal Components Versus Random Initialization. A Case Study

  سند علمی۲۰۱۲CoRRA. A. Akinduko, Eugenij Moiseevich Mirkes

  The performance of the Self-Organizing Map (SOM) algorithm is dependent on the initial weights of the map. The different initialization methods can broadly be classified into random and data analysis based initialization approach. In this paper, the performance of random initiali

• Fast, Exact Bootstrap Principal Component Analysis for p > 1 million.

  سند علمی۲۰۱۶Journal of the American Statistical AssociationAaron Fisher, Brian Caffo, Brian Schwartz, Vadim Zipunnikov

  Many have suggested a bootstrap procedure for estimating the sampling variability of principal component analysis (PCA) results. However, when the number of measurements per subject (p) is much larger than the number of subjects (n), calculating and storing the leading principal

• A Fast Incremental Multilinear Principal Component Analysis Algorithm

  سند علمی۲۰۱۱Jin Wang, Armando Barreto, Naphtali Rishe, Jean Andrian

  This study establishes the mathematical foundation for a fast incremental multilinear method which combines the traditional sequential Karhunen-Loeve (SKL) algorithm with the newly developed incremental modified fast Principal Component Analysis algorithm (IMFPCA). In accordance

• Fast Pruning Using Principal Components

  سند علمی۱۹۹۳NIPSAsriel U. Levin, Todd K. Leen, John E. Moody

  We present a new algorithm for eliminating excess parameters and improving network generalization after supervised training. The method, "Principal Components Pruning (PCP)", is based on principal component analysis of the node activations of successive layers of the network. It

  One of the best known techniques for multidimensional data analysis is the Principal Components Analysis (PCA). A number of local PCA neural models have been proposed to partition an input distribution into meaningful clusters. Each neuron of these models uses a certain number of

• Fast Iterative Kernel Principal Component Analysis

  سند علمی۲۰۰۷Journal of Machine Learning ResearchSimon Günter, Nicol N. Schraudolph, S. V. N. Vishwanathan

  We develop gain adaptation methods that improve convergence of the Kernel Hebbian Algorithm (KHA) for iterative kernel PCA (Kim et al., 2005). KHA has a scalar gain parameter which is either held constant or decreased according to a predetermined annealing schedule, leading to sl
