On Johnson’s “Sufficientness” Postulates for Feature-Sampling Models
In the 1920s, the English philosopher W.E. Johnson introduced a characterization of the symmetric Dirichlet prior distribution in terms of its predictive distribution. This is typically referred to as Johnson’s “sufficientness” postulate, and it has been

Efficient Feature Mapping in Classifying Proportional Data
In image classification, traditional kernels or feature mapping functions of Support Vector Machine(SVM) use discriminative features without considering the true nature of the data.

Modeling the Dirichlet distribution using multiplicative functions
For q,m,n,d ∈ N and some multiplicative function f > 0, we denote by T3(n) the sum of f(d) over the ordered triples (q,m,d) with qmd = n. We prove that Cesaro mean of distribution functions defined by means of T3 uniformly converges to the one-parameter ...

The two-parameter Poisson--Dirichlet point process [PDF]
The two-parameter Poisson--Dirichlet distribution is a probability distribution on the totality of positive decreasing sequences with sum 1 and hence considered to govern masses of a random discrete distribution.

A characterization of Dirichlet distributions
\textit{J. N. Darroch} and \textit{D. Ratcliff} [J. Am. Stat. Assoc. 66, 641- 643 (1971; Zbl 0228.62009)] have given a characterization of the Dirichlet distributions based on the properties of independence of various functions of the random variables \((X_ 1,X_ 2,...,X_ k)\) having a joint continuous distribution over the k-dimensional simplex: \(0 ...

New statistical inference for the Weibull distribution [PDF]
Weibull distribution has become a popular tool for modeling life data and improving growth in the field of reliability. The successful application of Weibull distribution to real data depends on the statistical power of hypotheses tests to a large extent.

Understanding Hierarchical Processes
Hierarchical stochastic processes, such as the hierarchical Dirichlet process, hold an important position as a modelling tool in statistical machine learning, and are even used in deep neural networks.

The supervised hierarchical Dirichlet process [PDF]
We propose the supervised hierarchical Dirichlet process (sHDP), a nonparametric generative model for the joint distribution of a group of observations and a response variable directly associated with that whole group.
