Practical Computing with Pattern Structures in FCART Environment
Ch. 7. P. 49-56.
A new general and efficient architecture for working with pattern structures, an extension of FCA for dealing with “complex” descriptions, is introduced and implemented in a subsystem of Formal Concept Analysis Research Toolbox (FCART). The architecture is universal in terms of possible dataset structures and formats, techniques of pattern structure manipulation.

We propose a new algorithm for recommender systems with numeric ratings which is based on Pattern Structures (RAPS). As the input the algorithm takes rating matrix, e.g., such that it contains movies rated by users. For a target user, the algorithm returns a rated list of items (movies) based on its previous ratings and ratings ...

In this paper, we introduce a modication of the lazy associative classication which addresses the graph classication problem. To deal with intersections of large graphs, graph intersections are approximated with all common subgraphs up to a xed size similarly to what is done with graphlet kernels. We illustrate the algorithm with a toy example and ...

The speed of full-text search directly affects the process of text analysis. Search engine creates a text index, which is used for fast full-text search. Solr and ElasticSearch are two popular search engines. A text analysis system requires fast implementing searching and indexing at the same time. This paper describes preprocessing workflow of the analysis ...

Decision tree learning is one of the most popular classifica- tion techniques. However, by its nature it is a greedy approach to finding a classification hypothesis that optimizes some information-based crite- rion. It is very fast but may lead to finding suboptimal classification hy- potheses. Moreover, in spite of decision trees being easily interpretable, ensembles ...

Formal concept analysis (FCA) is a well-founded method for data analysis and has many applications in data mining. Pattern structures is an extension of FCA for dealing with complex data such as sequences or graphs. However the computational complexity of computing with pattern structures is high and projections of pattern structures were introduced for simplifying ...
