      Most of the noise models in signal processing are either additive or multiplicative. However, the widely held wavelet shrinkage estimators for signal denoising deal only with additive noise. In this thesis, a new Bayesian ...
    • Nonparametric Bayesian analysis of some clustering problems 
      Ray, Shubhankar (Texas A&M University, 2006-10-30)
      Nonparametric Bayesian models have been researched extensively in the past 10 years following the work of Escobar and West (1995) on sampling schemes for Dirichlet processes. The infinite mixture representation of the ...
