Reducing the size of databases for multirelational classification: a subgraph-based approach

Hongyu Guo, Herna L. Viktor, Eric Paquet
2012 Journal of Intelligent Information Systems  
Multirelational classification aims to discover patterns across multiple interlinked tables (relations) in a relational database.  ...  Our method identifies a set of strongly uncorrelated subgraphs from the original database schema, to use for training, and discards all others.  ...  Multirelational data mining algorithms often need to use information from both the five relations and the four join relationships to build a relational model to categorize each tuple from the target relation  ...

Relational Classification using Multiple View Approach with Voting

Shraddha Modi
2013 International Journal of Computer Applications  
To classify data from relational format need of multirelational classification arise which is used to analyze relational data and used to predict behaviour and unknown pattern automatically.  ...  Classification is an important task in data mining and machine learning, in which a model is generated based on training dataset and that model is used to predict class label of unknown dataset.  ...  Conventional single-table data mining algorithms such as such as Decision Trees, SVMs, or Neural Networks are used in order to learn the target concept from each view of the database separately.  ...

Identifying and Preventing Data Leakage in Multi-relational Classification

Hongyu Guo, Herna L. Viktor, Eric Paquet
2010 2010 IEEE International Conference on Data Mining Workshops  
Abstract-Relational database mining, where data are mined across multiple relations, is increasingly commonplace.  ...  For instance, consider a financial database classification task to determine whether a loan is considered to be high risk.  ...  Also, Guo and Viktor [21] utilized this formula to select a subset of useful views for multirelational classification.  ...

A Relative Analysis of Multi-Relational Decision Tree Learning Algorithm

2017 International Journal of Science and Research (IJSR)  
We had used some of the real world data sets from multiparous data mining sweepstakes and accomplished a graphical comparison for the forenamed two approaches.  ...  In order to deal with records in relational databases MRDTL broadens TILDE"s [18] approach. First order logic clauses are used to represent decisions (nodes) in the tree.  ...  Hence, the precision of decision trees constructed using MRDTL becomes a major concern as these missing value attribute are pretty common in real multirelational datasets.  ...
