Summary form only given. Data mining is commonly used in attempts to induce association rules from transaction data. Most previous studies focused on mining from binary valued data. Transactions in real-world applications, however, usually consist of quantitative values. Designing a sophisticated data-mining algorithm able to deal with various types of data presents a challenge to workers in this...
Summary form only given. First, we briefly advocate a need of natural language based methods in data mining, notably whew domain experts have a limited knowledge of modern tools of information technology. We present some approaches to linguistic summarization of sets of (numeric and/or textual) data, and show that a fuzzy logic based approach by Yager (1982), notably in its extended and implementable...
Summary form only given. Granular computing (GrC) is a pragmatic approach to data and knowledge engineering. Roughly, it is a methodology that involves elements (data) and subsets (knowledge). We will illustrate the idea via a web application. In traditional web processing, we often represent a document by a set of keywords. In GrC, let us call it granular representation, we include the knowledge...
The bulk of contents out on the Internet continue to grow at an astounding pace. As computing and communications become ubiquitous, we are entering the mobile Internet computing era, where people, devices, and vehicles are connected at all time and the Internet access capability is being embedded in billions of wireless devices such as PDAs, cellular phones, and computers embedded in vehicles (e.g...
One of the relations used with granularity is indistinguishability, where distinguishable entities in a finer-grained granule are indistinguishable in a coarser-grained granule. This relation is a subtype of equivalence relation, which is used in the other direction to create finer-grained granules. Together with the notion of similarity, we formally prove some intuitive properties of the indistinguishability...
This paper discusses forms and structures of some important models of granular computing. A class of models is called relation based models, which are induced by equivalence relations, more general, by general binary relations or neighborhood systems. Another class of models of granular computing, called covering based models, are proposed and discussed in detail, which are induced by coverings of...
One of the important thoughts in mathematical logic is the way of formalization for practical statements. This paper just adopts the method to make formalization for granular computing. Based on this logical method, formulas of a particular kind are constructed on a universal set U. The structure consisting of the universal set, and the all-formula set, is defined as a granular space. Through a formula...
2600 years ago, YinYang was born in the ancient China with the theme "Taiji (one matter) produces YinYang; YinYang produces four forms; the four forms lead to eight diagrams; and the eight diagrams can have 64 direct combinations." This theme can be called YinYang 1-2-4-8-64. An equilibrium-based scientific decoding of YinYangl-2-4-8-64 is presented which states "Equilibrium (the one...
The aim of granular computing is to obtain feasible approximate solutions satisfied enough with least complexity. The logic reasoning process using extension method actually implies the ideal of granular computing. This paper uses the relation-element as the measure of granulation and applies granular computing to the reasoning process of the extension criminal reconnaissance system to reduce the...
In the past decade, many papers about granular computing(GrC) have been published, but the key points about granular computing(GrC) are still unclear. In this paper, we try to find the key points of GrC in the information transformation of the pattern recognition. The information similarity is the main point in the original insight of granular computing (GrC) proposed by Zadeh(1997[1]). Many GrC researches...
The principles of granular computing have been applied in many fields. Current developing in granular computing is more a theoretical perspective than a set of computational methods or processes. This paper attempts to narrow the gap between the theoretical concept and real-world application of granular computing. Multitasking is a method with multiple tasks or processes share with common resources...
Rough logic is a nonstandard logic defined information systems. In the paper, meaning of the logical formulas is defined as granulation. Operations, related properties of the granulations are discussed further. Lock resolution of the granulations is studied. Studying significance of the granulations will offer an application in inference of expert systems. Which will also offer a new idea for the...
Rough set theory is based on information granules. This paper studies information granules based on a decision logic language in information tables. In this paper, the theorems of determining definable granules and definable partitions are given. Furthermore, this paper gives the definitions of the definable upper and lower approximations of indefinable granules, and studies their properties. Through...
