A dissimilarity measure for mixed nominal and …
In this part, a new dissimilarity measure between two objects is defined based on rough membership function. The data is assumed to be in a table, where each row(tuple) represents facts about an object. A data table is also called an information system. We exploit this dissimilarity measure which has been used … See more Formally, a nominal information system is a quadruple IS = (U, A, V, f), where: U, the nonempty set of data points,called the universe; A, the nonempty set of attributes; V, the union of all attribute domains,i.e., V = … See more Let IS = (U, A, V, f) be a nominal information system and P \subseteq A, a binary relation IND(P), called indiscernibility relation, is defined as: Let U/IND(P) = {[x]p x ∈ … See more Let IS = (U, A, V, f) be a nominal information system, and P\subseteq A. For any a ∈ P and x, y ∈ U, we have: 1. (1)Symmetry sima(x, … See more Let IS = (U, A, V, f) be a nominal information system and P \subseteq A. For any a ∈ P and x, y ∈ U,a similarity measure between objects x and y with respect to ais … See more WebJul 27, 2016 · The distance d (c1; c2) is as shown in equation. d (c1, c2) = d (s) * d (o) Dissimilarity in Nominal Variable. This kind of variable has multiple categories also not in order. So there is difficulty in calculating difference between nominal variables. In this case we use dependant variables on categorical attribute. Web'Difference' has a greater range of meanings than 'dissimilarity'. It can refer both to a difference between one entity and another and to a different state or condition existing in … hermione trollstav
