    • Wavelet-based Data Reduction Techniques for Process Fault Detection 

      Jeong, Myong-Kee; Lu, Jye-Chyi; Huo, Xiaoming; Vidakovic, Brani; Chen, Di (Georgia Institute of Technology, 2004)
      To handle potentially large and complicated nonstationary data curves, this article presents new data reduction methods based on the discrete wavelet transform. The methods minimize objective functions to balance the ...
    • Wavelet-Based Estimation of a Discriminant Function 

      Chang, Woojin; Kim, Seong-Hee; Vidakovic, Brani (Georgia Institute of Technology, 2002)
      In this paper we consider wavelet-based binary linear classifiers. Both consistency results and implementational issues are addressed. We show that under mild assumptions on the design density wavelet discrimination rules ...
    • Γ -Minimax Wavelet Shrinkage: A Robust Incorporation of Information about Energy of a Signal in Denoising Applications 

      Angelini, Claudia; Vidakovic, Brani (Georgia Institute of Technology, 2001)
      In this paper we propose a method for wavelet- filtering of noisy signals when prior information about the energy of the signal of interest is available. Assuming the independence model, according to which the wavelet ...
