چکیده
Eq. (1) defines the distribution of a relation strength for irrelevant data entries φ. Eq. (2) defines an relation strength from the clsuter k to cluster l for relevant data entries. λi, i = 1, 2, . . . , N in Eq. (3) denotes the probability of a relevancy flag variable ri being 1. ri = {0, 1} in Eq. (4) indicates whether the object i is relevant or not. zi = k ∈ {1, 2, . . . } indicates the clsuter assignment of the object i. zi is also represented as a 1-of-K type vector: i.e. if zi = k, then zi,k = 1 and zi,k′,k = 0. The relevancy variables R = {ri}i=1,...,N affects the remaining generative process. If ri = 1, then zi is chosen based on the CRP as in Eq. (5). Otherwise (ri = 0), then its cluster assignments is set to

Rings with a setwise polynomial-like condition
Let $R$ be an infinite ring. Here we prove that if $0_R$ belongs to ${x_1x_2cdots x_n ;|; x_1,x_2,dots,x_nin X}$ for every infinite subset $X$ of $R$, then $R$ satisfies the polynomial identity $x^n=0$. Also we prove that if $0_R$ belongs to ${x_1x_2cdots x_n-x_{n+1} ;|; x_1,x_2,dots,x_n,x_{n+1}in X}$ for every infinite subset $X$ of $R$, then $x^n=x$ for all $xin R$.
متن کاملA relation between infinite subsets and exterior center in groups
Let G be a group. Neumann to answer a question of Paul Erdos proved that every infinite subset of G has two different comuting elements if and only if G is center-by-finite. In this paper, we deal with Erdoschr('39')s question in different aspect and we show that every infinite subset X of G has two different elements x and y such that x^y=1 if and only if the exterior center of G ihas finit...
متن کاملMetadata Enrichment for Automatic Data Entry Based on Relational Data Models
The idea of automatic generation of data entry forms based on data relational models is a common and known idea that has been discussed day by day more than before according to the popularity of agile methods in software development accompanying development of programming tools. One of the requirements of the automation methods, whether in commercial products or the relevant research projects, ...
متن کاملSubset Infinite Relational Models
We propose a new probabilistic generative model for analyzing sparse and noisy pairwise relational data, such as friend-links on social network services and customer records in online shops. Real-world relational data often include a large portion of non-informative pairwise data entries. Many existing stochastic blockmodels suffer from these irrelevant data entries because of their rather simp...
متن کاملAn Extension of the Infinite Relational Model Incorporating Interaction between Objects
The Infinite Relational Model (IRM) introduced by Kemp et al. (Proc. AAAI2006) is one of the well-known probabilistic generative models for the coclustering of relational data. The IRM describes the relationship among objects based on a stochastic block structure with infinitely many clusters. Although the IRM is flexible enough to learn a hidden structure with an unknown number of clusters, it...
