If only it were true: the problem with the four conditionals [PDF]

open access: yes, 2010
The traditional division of conditionals into four main types (zero, first, second, and third) has long been called into question. Unfortunately, the awareness that this description does not reflect conditional patterns in actual usage has not generally ...

Representing Graphs as Bag of Vertices and Partitions for Graph Classification

open access: yesData Science and Engineering, 2018
Graph classification is a difficult task because finding a good feature representation for graphs is challenging. Existing methods use topological metrics or local subgraphs as features, but the time complexity for finding discriminatory subgraphs or ...

Detecting Incremental Frequent Subgraph Patterns in IoT Environments

open access: yesSensors, 2018
As graph stream data are continuously generated in Internet of Things (IoT) environments, many studies on the detection and analysis of changes in graphs have been conducted. In this paper, we propose a method that incrementally detects frequent subgraph

Frequent State Transition Patterns of Multivariate Time Series

open access: yesIEEE Access, 2019
Sequence pattern discovery is a key issue in multivariate time series analysis. Popular approaches first obtain the pattern of each single-variate time series and then obtain cross-variate associations.

A Sliding Window-Based Approach for Mining Frequent Weighted Patterns Over Data Streams

open access: yesIEEE Access, 2021
The mining of frequent weighted patterns (FWPs) that considers the different semantic significance (weight) of items is more suitable for practice than the mining of frequent patterns. Therefore, it plays a vital role in real-world scenarios.

An Efficient Genetic Algorithm for Discovering Diverse-Frequent Patterns

open access: yes, 2015
Working with exhaustive search on large dataset is infeasible for several reasons. Recently, developed techniques that made pattern set mining feasible by a general solver with long execution time that supports heuristic search and are limited to small ...

Conserved substitution patterns around nucleosome footprints in eukaryotes and Archaea derive from frequent nucleosome repositioning through evolution. [PDF]

open access: yes, 2013
Nucleosomes, the basic repeat units of eukaryotic chromatin, have been suggested to influence the evolution of eukaryotic genomes, both by altering the propensity of DNA to mutate and by selection acting to maintain or exclude nucleosomes in particular ...

Analysis and Classification of Fake News Using Sequential Pattern Mining

open access: yesBig Data Mining and Analytics
Disinformation, often known as fake news, is a major issue that has received a lot of attention lately. Many researchers have proposed effective means of detecting and addressing it.
