Mining Best Closed Itemsets for Projection-antimonotonic Constraints in Polynomial Time
CoRR, 2017 The exponential explosion of the set of patterns is one of the main challenges in pattern mining. This challenge is approached by introducing a constraint for pattern selection. One of the first constraints proposed in pattern mining is support (frequency) of a pattern in a dataset.

, 2014 Over the last several years, graph mining has emerged as a new field within contemporary data mining. One of the central tasks is the search for subgraphs, called patterns, that occur frequently in either a collection of graphs (e.g.

Dynamical Analysis of a Memristive Chua’s Oscillator Circuit
, 2023 In this work, a novel memristive Chua’s oscillator circuit is presented. In the proposed circuit, a linear negative resistor, which is parallel coupled with a first-order memristive diode bridge, is used instead of the well-known Chua’s diode.

A chaotic circuit with bi-color LED as a nonlinear element
In this work, a simple 3D chaotic circuit is experimentally studied. The proposed circuit is described by a 3-D dynamical system with two nonlinear terms, which are the same hyperbolic sine functions implemented with simple Bi-color LEDs.
