Basic statistical estimation outperforms machine learning in monthly prediction of seasonal climatic parameters
Hussein, Eslam A.; Ghaziasgar, Mehrdad; Thron, Christopher (MPDI, 2021)Machine learning (ML) has been utilized to predict climatic parameters, and many successes have been reported in the literature. In this paper, we scrutinize the effectiveness of five widely used ML algorithms in the ... -
Comparison of phenolic content and antioxidant activity for fermented and unfermented rooibos samples extracted with water and methanol
Hussein, Eslam A.; Thron, Christopher; Ghaziasgar, Mehrdad (MPDI, 2022)Rooibos is brewed from the medicinal plant Aspalathus linearis. It has a well-established wide spectrum of bio-activity properties, which in part may be attributed to the phenolic antioxidant power. The antioxidant ... -
Complex sequential data analysis: A systematic literature review of existing algorithms
Dandajena, Kudakwashe; Venter, Isabella M.; Ghaziasgar, Mehrdad (SAICSIT, 2020)This paper provides a review of past approaches to the use of deep-learning frameworks for the analysis of discrete irregularpatterned complex sequential datasets. A typical example of such a dataset is financial data ... -
Groundwater prediction using machine-learning tools
Hussein, Eslam A.; Thron, Christopher; Ghaziasgar, Mehrdad (MPDI, 2020)Predicting groundwater availability is important to water sustainability and drought mitigation. Machine-learning tools have the potential to improve groundwater prediction, thus enabling resource planners to: (1) anticipate ... -
Regional rainfall prediction using support vector machine classification of large-scale precipitation maps
Hussein, Eslam A.; Ghaziasgar, Mehrdad; Thron, Christopher (Institute of Electrical and Electronics Engineers Inc., 2020)Rainfall prediction helps planners anticipate potential social and economic impacts produced by too much or too little rain. This research investigates a class-based approach to rainfall prediction from 1-30 days in advance. ... -
A surface acoustic wave touchscreen-type device using two transducers
Ghaziasgar, Mehrdad; Connan, James (2008)Current wireless human-computer interaction devices such as wireless mice and touchscreens, by and large, incorporate a sophisticated electronic architecture. The sophistication achieves wireless capabilities but carries ...
