General Approach to Triadic Concept Analysis
Triadic concept analysis (TCA) is an extension of formal concept analysis (dyadic case) which takes into account modi (e.g. time instances, conditions, etc.) in addition to objects and attributes. Thus instead of 2-dimensional binary tables TCA concerns with 3-dimensional binary tables. In our previous work we generalized TCA to work with grades instead of binary data; in the present paper we s...
متن کاملA Triadic Approach to Formal Concept Analysis
1 Triadic Con tex t s Formal Concept Analysis views concepts as means of intersubjective understanding in situations of purpose-oriented action. The formalization of concepts and concept systems shall especially support the interpretat ion and communicat ion of conceptual relationships in different situations. This requires tha t the formalization of concepts has to be t ransparent and simple, ...
متن کاملQuery-based Biclustering using Formal Concept Analysis
Biclustering methods have proven to be critical tools in the exploratory analysis of high-dimensional data including information networks, microarray experiments, and bag of words data. However, most biclustering methods fail to answer specific questions of interest and do not incorporate prior knowledge and expertise from the user. To this end, query-based biclustering algorithms that are rece...
متن کاملConcept Learning from Triadic Data
We propose extensions of the classical JSM-method and the Naı̈ve Bayesian classifier for the case of triadic relational data. We performed a series of experiments on various types of data (both real and synthetic) to estimate quality of classification techniques and compare them with other classification algorithms that generate hypotheses, e.g. ID3 and Random Forest. In addition to classificati...
متن کاملLattices of Triadic Concept Graphs
Triadic concept graphs have been introduced as a mathema-tization of conceptual graphs with subdivision. In this paper it is shown that triadic concept graphs of a triadic power context family always form a complete lattice with respect to the generalization order. For stating this result, a clariication of the notion of generalization is needed. It turns out that the generalization order may b...
