Delta-Closure Structure for Studying Data Distribution

no code implementations13 Oct 2022 Aleksey Buzmakov, Tatiana Makhalova, Sergei O. Kuznetsov, Amedeo Napoli

In this paper, we revisit pattern mining and study the distribution underlying a binary dataset thanks to the closure structure which is based on passkeys, i. e., minimum generators in equivalence classes robust to noise.

Discovery data topology with the closure structure. Theoretical and practical aspects

no code implementations6 Oct 2020 Tatiana Makhalova, Aleksey Buzmakov, Sergei O. Kuznetsov, Amedeo Napoli

The closure structure allows one to understand the topology of the dataset in the whole and the inherent complexity of the data.

The Comparison of Methods for Individual Treatment Effect Detection

no code implementations3 Dec 2019 Aleksey Buzmakov, Daria Semenova, Maria Temirkaeva

Today, treatment effect estimation at the individual level is a vital problem in many areas of science and business.

Mining Best Closed Itemsets for Projection-antimonotonic Constraints in Polynomial Time

no code implementations28 Mar 2017 Aleksey Buzmakov, Sergei O. Kuznetsov, Amedeo Napoli

One of the first constraints proposed in pattern mining is support (frequency) of a pattern in a dataset.

Fast Generation of Best Interval Patterns for Nonmonotonic Constraints

no code implementations2 Jun 2015 Aleksey Buzmakov, Sergei O. Kuznetsov, Amedeo Napoli

In this paper we consider stability and $\Delta$-measure, which are nonmonotonic constraints, and apply them to interval tuple datasets.

On mining complex sequential data by means of FCA and pattern structures

no code implementations9 Apr 2015 Aleksey Buzmakov, Elias Egho, Nicolas Jay, Sergei O. Kuznetsov, Amedeo Napoli, Chedy Raïssi

Pattern structures are used for mining complex data (such as sequences or graphs) and are based on a subsumption operation, which in our case is defined with respect to the partial order on sequences.
