We present a multichannel speech enhancement method based on MAP speech spectral magnitude estimation using a generalized gamma model of speech prior distribution, where the model parameters are adapted from actual noisy speech in a frame-by-frame manner. The utilization of a more general prior distribution with its online adaptive estimation is shown to be effective for speech spectral estimat...

Introduction. A number of known families of probability distributions can be derived from requirements that are physical in the sense that they describe the random behavior of the event under consideration. The Poisson process is typical of these: If X{t) is equal to the number of occurrences of a specified event in the interval [0, t), then one can show that X (t) has, for each t, a Poisson di...

G02GDF Note: before using this routine, please read the Users' Note for your implementation to check the interpretation of bold italicised terms and other implementation-dependent details. 1 Purpose G02GDF fits a generalized linear model with gamma errors. 3 Description A generalized linear model with gamma errors consists of the following elements: (a) a set of n observations, y i , from a gam...

This paper deals with the joint modeling of color textures in the context of Content Based Image Retrieval (CBIR). We propose a generic multivariate model based on the Generalized Gamma distribution to describe the marginal behavior of texture wavelet detail subbands. Then the information of dependence across color components is incorporated in the modeling process using the Gaussian copula. Th...

This work is devoted to the formulation and derivation of the κ − μ/gamma distribution which corresponds to A physical fading model. This distribution is composite and is based on the well known κ − μ generalized multipath model and the gamma shadowing model. A special case of the derived model constitutes the κ − μ Extreme/gamma model which accounts for severe multipath and shadowing effects. ...

Flood frequency analysis (FFA) is needed for the design of water engineering and hydraulic structures. The choice of an appropriate frequency distribution is one of the most important issues in FFA. A key problem in FFA is that no single distribution has been accepted as a global standard. The common practice is to try some candidate distributions and select the one best fitting the data, based...

In this paper, we introduce the concept of interval valued fuzzy weak bi-ideals of $Gamma$-near-rings, which is a generalized concept of fuzzy weak bi-ideals of $Gamma$- near-rings. We also characterize some properties and examples of interval valued fuzzy weak bi-ideals of $Gamma$-near-rings.
