    • Issues related to data mining with self organizing maps 

      Jain, Abha (2004)
      This thesis demonstrates that the clustering by Kohonen's Self-Organizing Map algorithm (KSOM) can be significantly improved by magnification control. As a second contribution, the thesis proposes a fully automated technique ...

      Rustagi, Navin; Hampton, Oliver A; Li, Jie; Xi, Liu; Gibbs, Richard A; Plon, Sharon E; Kimmel, Marek; Wheeler, David A (2016-04-27)
      Abstract Background Detection of tandem duplication within coding exons, referred to as internal tandem duplication (ITD), remains challenging due to inefficiencies in ...
    • Iterative design of l(p) digital filters 

      Vargas, Ricardo Arturo (2008)
      The design of digital filters is a fundamental process in the context of digital signal processing. Being essential building blocks, digital filters are used in diverse areas ranging from medical imaging or audio and video ...
    • Iterative Multiuser Detection and Decoding 

      Das, Suman; Erkip, Elza; Cavallaro, Joseph R.; Aazhang, Behnaam (1998-11-20)
      An iterative detection and decoding algorithm is explored for a convolutionally coded DS-CDMA system. The optimum decoding strategy is to consider the trellises of all the users simultaneously, but this has exponential ...
    • Iterative Temporal Motion Planning for Hybrid Systems in Partially Unknown Environments 

      Maly, Matthew R.; Lahijanian, Morteza; Kavraki, Lydia E.; Kress-Gazit, Hadas; Vardi, Moshe Y. (2013)
      This paper considers the problem of motion planning for a hybrid robotic system with complex and nonlinear dynamics in a partially unknown environment given a temporal logic specification. We employ a multi-layered synergistic ...
    • ITERATIVELY STRUCTURED INFORMATION PROCESSORS 

      KANE, GERALD RANDOLPH (1972)
    • Jacobi-like Matrix Factorizations with CORDIC-based Inexact Diagonalizations 

      Hemkumar, Nariankadu D.; Cavallaro, Joseph R. (1994-06-20)
      We propose a CORDIC-based Jacobi-like method for parallel computation of the eigenvalues of Hermitian (and real symmetric) matrices and the SVD of real matrices using inexact diagonalizations. It is predicted on the fact ...
    • Joint Compression and Speckle Reduction of SAR Images using Embedded Zerotree Models 

      Odegard, Jan E.; Guo, Haitao; Burrus, C. Sidney; Baraniuk, Richard G. (1996-03-01)
      We propose a new method for speckle reduction in synthetic aperture radar (SAR) imagery based on the embedded zerotree image compression algorithm. This new approach to denoising is inspired by the realization that the ...
    • Joint Detection Strategies for Orthogonal Frequency Division Multiplexing 

      Ahmed, Nadeem (2000-04-20)
      Traditional OFDM implementations use conventional Fourier filters for data modulation, via the IFFT operation. Much research suggests wavelet based OFDM provides performance gains, due to superior spectral containment ...

      Ahmed, Nadeem (2000)
      Traditional OFDM implementations use conventional Fourier filters for data modulation, via the IFFT operation. Much research suggests wavelet based OFDM provides performance gains, due to superior spectral containment ...
    • Joint Distributions for Arbitrary Variables 

      Cohen, Leon; Baraniuk, Richard G. (1994-10-01)
      We compare the methods of Cohen (1971) and of Baraniuk and Jones (see Proc. IEEE ICASSP-93, p.320-323, 1993) for obtaining joint distributions for arbitrary variables. We show that the two methods produce identical results ...
    • Joint Distributions of Arbitrary Variables Made Easy 

      Baraniuk, Richard G. (1998-09-01)
      The successful application of joint time-frequency distributions to problems in time-varying spectral analysis has stimulated considerable interest in distributions of other variables for use when a strict time-frequency ...

      Baraniuk, Richard G. (1998-10-01)
      In this paper, we propose a simple framework for studying certain distributions of variables beyond time-frequency and time-scale. When applicable, our results turn the theory of joint distributions of arbitrary variables ...

      Sayeed, Akbar M.; Aazhang, Behnaam (1998-11-20)
      We present a new framework for code-division multiple access (CDMA) communication over fast fading mobile wireless channels. The performance of the RAKE receiver, which is at the heart of existing CDMA systems, degrades ...
