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…
On-Line Condition Monitoring using Computational Intelligence
C. B. Vilakazi, T. Marwala, P. Mautla +1
This paper presents bushing condition monitoring frameworks that use multi-layer perceptrons (MLP), radial basis functions (RBF) and support vector machines (SVM) classifiers. The…
Fuzzy and Multilayer Perceptron for Evaluation of HV Bushings
Sizwe M. Dhlamini, Tshilidzi Marwala, Thokozani Majozi
The work proposes the application of fuzzy set theory (FST) to diagnose the condition of high voltage bushings. The diagnosis uses dissolved gas analysis (DGA) data from bushings b…
Fault Classification using Pseudomodal Energies and Neuro-fuzzy modelling
Tshilidzi Marwala, Thando Tettey, Snehashish Chakraverty
This paper presents a fault classification method which makes use of a Takagi-Sugeno neuro-fuzzy model and Pseudomodal energies calculated from the vibration signals of cylindrical…
Response Prediction of Structural System Subject to Earthquake Motions using Artificial Neural Network
S. Chakraverty, T. Marwala, Pallavi Gupta +1
This paper uses Artificial Neural Network (ANN) models to compute response of structural system subject to Indian earthquakes at Chamoli and Uttarkashi ground motion data. The syst…
Artificial Intelligence for Conflict Management
E. Habtemariam, T. Marwala, M. Lagazio
Militarised conflict is one of the risks that have a significant impact on society. Militarised Interstate Dispute (MID) is defined as an outcome of interstate interactions, which…
