Relationship between Diversity and Perfomance of Multiple Classifiers for Decision Support
R. Musehane, F. Netshiongolwe, F. V. Nelwamondo +2
The paper presents the investigation and implementation of the relationship between diversity and the performance of multiple classifiers on classification accuracy. The study is c…
The use of entropy to measure structural diversity
L. Masisi, V. Nelwamondo, T. Marwala
In this paper entropy based methods are compared and used to measure structural diversity of an ensemble of 21 classifiers. This measure is mostly applied in ecology, whereby speci…
The Effect of Structural Diversity of an Ensemble of Classifiers on Classification Accuracy
Lesedi Masisi, Fulufhelo V. Nelwamondo, Tshilidzi Marwala
This paper aims to showcase the measure of structural diversity of an ensemble of 9 classifiers and then map a relationship between this structural diversity and accuracy. The stru…
Autoencoder, Principal Component Analysis and Support Vector Regression for Data Imputation
Vukosi N. Marivate, Fulufhelo V. Nelwamodo, Tshilidzi Marwala
Data collection often results in records that have missing values or variables. This investigation compares 3 different data imputation models and identifies their merits by using…
Condition Monitoring of HV Bushings in the Presence of Missing Data Using Evolutionary Computing
Sizwe M. Dhlamini*, Fulufhelo V. Nelwamondo**, Tshilidzi Marwala**
The work proposes the application of neural networks with particle swarm optimisation (PSO) and genetic algorithms (GA) to compensate for missing data in classifying high voltage b…
HMM Speaker Identification Using Linear and Non-linear Merging Techniques
Unathi Mahola, Fulufhelo V. Nelwamondo, Tshilidzi Marwala
Speaker identification is a powerful, non-invasive and in-expensive biometric technique. The recognition accuracy, however, deteriorates when noise levels affect a specific band of…
