Knowledge discovery in data using formal concept analysis and random projections
نویسنده
چکیده
In this paper our objective is to propose a random projections based formal concept analysis for knowledge discovery in data. We demonstrate the implementation of the proposed method on two real world healthcare datasets. Formal Concept Analysis (FCA) is a mathematical framework that offers a conceptual knowledge representation through hierarchical conceptual structures called concept lattices. However, during the design of a concept lattice, complexity plays a major role.

Using Formal Concept Analysis in Mathematical Discovery
Formal concept analysis (FCA) comprises a set of powerful algorithms which can be used for data analysis and manipulation, and a set of visualisation tools which enable the discovery of meaningful relationships between attributes of the data. We explore the potential of combining FCA and mathematical discovery tools in order to better facilitate discovery tasks. In particular, we propose a nove...
متن کاملFCART: A New FCA-based System for Data Analysis and Knowledge Discovery
We introduce a new software system called Formal Concept Analysis Research Toolbox (FCART). Our goal is to create a universal integrated environment for knowledge and data engineers. FCART is constructed upon an iterative data analysis methodology and provides a built-in set of research tools based on Formal Concept Analysis techniques for working with object-attribute data representations. The...
متن کاملKnowledge Discovery from Texts with Conceptual Graphs and FCA
Building conceptual lattices from conceptual graphs looks as natural way in Formal Concept Analysis but still is not discovered at length. If conceptual graphs are acquired from natural language texts then they contain specific material for knowledge discovery. Conceptual graphs serve as semantic models of text sentences and the data source for concept lattice. With the use of concept lattice i...
متن کاملConceptual Knowledge Discovery and Data Analysis
In this paper, we discuss Conceptual Knowledge Discovery in Databases (CKDD) in its connection with Data Analysis. Our approach is based on Formal Concept Analysis, a mathematical theory which has been developed and proven useful during the last 20 years. Formal Concept Analysis has led to a theory of conceptual information systems which has been applied by using the management system TOSCANA i...
متن کاملLattices and Patterns
This work is aimed at finding interesting patterns in knowledge discovery applications. We first apply formal concept analysis methods for deriving concepts from particular data sets. We also investigate concepts stabilities by removing attributes from the same data set. Another way to search for interesting patterns is to build nested lattices and compare the obtained concepts with the ones re...
