The attribute reductions of three-way concept lattices

Concept Lattices Constrained by Attribute Dependencies

The input data to formal concept analysis consist of a collection of objects, a collection of attributes, and a table describing a relationship between objects and attributes (so-called formal context). Very often, there is an additional information about the objects and/or attributes available. In the analysis of the data, the additional information should be taken into account. We consider a ...

Using Concept Lattices as a Visual Assistance for Attribute Selection

the influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry

بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...

A Novel Approach to Attribute Reduction in Formal Concept Lattices

The theory of concept lattice is an efficient tool for knowledge representation and knowledge discovery. One of the key problems of knowledge discovery is attribute reduction. This paper presents a novel approach to attribute reduction in formal concept lattices. The approach employs all the extents of the meet-irreducible elements in the lattice. Each of them determines a family of attribute s...
