A maximal prime subgraph decomposition junction tree (MPD-JT) is a useful computational structure that facilitates lazy propagation in Bayesian networks (BNs). A graphical method was proposed to construct an MPD-JT from a BN. In this paper, we present a new method from a relational database (RDB) perspective which sheds light on the semantic meaning of the previously proposed graphical algorithm.

Graphical passwords, as opposed to textual require the user pick pictures or draw symbols rather than input written letters. They are an option that may be explored in order get over issues caused by system of passwords based on text. It has been hypothesized graphical more difficult crack using a brute force technique figure out through guessing. This paper proposes authentication password met...

The graphical password patterns are in the rising trend in world with the abundance of the touch screen devices. A variety of touch screen devices are present for the users such as mobile phones, tables, touch-enabled laptops, touchenabled notebooks, etc. The graphical password has evolved with the invention of the touch-screen devices. The popular graphical schemes known as Pass-Go Pattern, Pa...

We consider the problem of estimating a sparse precision matrix of a multivariate Gaussian distribution, including the case where the dimension p exceeds the sample size n. Gaussian graphical models provide an important tool in describing conditional independence through presence or absence of the edges in the underlying graph. A popular non-Bayesian method of estimating a graphical structure i...
