Research Output
Research output can be seen as the result of research and study which is done by an institutions' research community - usually in publicised form such as an article or book. The NWU-IR drives to raise the visibility of the outputs both locally and internationally to create further awareness of what is being done by the NWU.

Unsupervised Fine-tuning of Speaker Diarisation Pipelines using Silhouette Coefficients
(SACAIR, 2021)We investigate the use of silhouette coefficients in cluster analysis for speaker diarisation, with the dual purpose of unsupervised fine-tuning during domain adaptation and determining the number of speakers in an audio ... -
Genomic exploration of Bacillus thuringiensis MORWBS1.1 - candidate biocontrol agent,predicts genes for biosynthesis of zwittermicin, 4,5-DOPA dioxygenase extradiol, and quercetin 2,3-dioxygenase
(American Phytopathological Society, 2021)Many strains fromBacillus thuringiensisare known for theirgenomic robustness and antimicrobial potentials. As a result, thequest for their biotechnological applications, especially in theagroindustry (e.g., as biopesticides), ... -
Morpho-agronomic evaluation of lagenaria siceraria landraces and their F₁ populations
(MDPI, 2022)Lagenaria siceraria is one of the most important cucurbitaceous vegetables due to its prolific bearing habit, its edibility as a cooked vegetable, and its low cost of cultivation. The objective of this study was to evaluate ... -
A regression model for predicting the likelihood of reporting a crime based on the victim’s demographic variables and their perceptions towards the police
(De Gruyter, 2020)Despite the growing criminal activities in South Africa,many victims still do not report the crimes, therefore there was a need to understand the determinants of the likelihood of reporting a crime in the country. Binary ... -
"Bloed" (uit Melk): Tuiskoms in Afrika
(Suid-Afrikaanse Akademie vir Wetenskap en Kuns, 2021)‘n Groot gedeelte van Elsa Joubert se vroeë oeuvre word tematies oorheers deur die wyse waarop die mens van Afrika telkens nuwe insigte vorm omtrent die werklikheid van diepgeankerde wortels in verskillende wêrelde: ... -
Ecocritical Concerns in Select Afrikaans Narrative Works: Critical Perspectives
(UNISA Press, 2021)Environmentally oriented literary and cultural studies, or ecocriticism for short, gained traction in the United States of America in the late 1980s. It took root in South Africa no earlier than the start of this century ... -
Identifying the drivers of trade finance in South Africa
(Taylor & Francis, 2020)Trade finance (or bank intermediated trade finance) plays an integral role in facilitating trade across the globe: most studies assert that trade finance (TF) forms part of more than 80% of total global trade. Although TF ... -
Implementation of a multimodal academic literacy resource at a South African University: a critical autoethnographic reflection
(IGI Global, 2021)As a lecturer at a higher education institution in South Africa, the author is conscious of an emphasis placed on multimodal resources as part of the globally experienced shift to teach remotely due to the COVID-19 epidemic. ... -
Anthelmintic potency of Rumex crispus L. extracts against Caenorhabditis elegans and non-targeted identification of the bioactive compounds
(Elsevier, 2021)Traditional healers and ethnoveterinary therapists use several medicinal plants, such as Rumex crispus L., to treat endoparasite infections. R. crispus has been established by researchers to be effective agasint a few ... -
Research progression of the Genus Merremia: a comprehensive review on the nutritional value, ethnomedicinal uses, phytochemistry, pharmacology, and toxicity
(MDPI, 2021)The genus Merremia Dennst. ex Endl. (Convolvulaceae) is a rich source of structurally diverse phytochemicals with therapeutic relevance. This review presents the first comprehensive, up-to-date information and research ... -
South African wild fruits and vegetables under a changing climate: the implications on health and economy
(Elsevier, 2021)Overdependence on exotic plant species constitutes a major setback for the consumption of wild fruits and vegetables among South Africans. The country is not spared from the adverse effects of climate change which play a ... -
Global trends of green pesticide research from 1994 to 2019: a bibliometric analysis
(Journal of Toxicology, 2021)The fast-growing world population places food production under enormous pressure to ensure food security. One of the most common methods to increase food production is the use of pesticides, but the continuous use thereof ... -
Tracking translation invariance in CNNs
(Southern African Conference for Artificial Intelligence Research, 2020)Although Convolutional Neural Networks (CNNs) are widely used, their translation invariance (ability to deal with translated inputs) is still subject to some controversy. We explore this question using translation-sensitivity ... -
Stride and translation invariance in CNNs
(Southern African Conference for Artificial Intelligence Research, 2020)Convolutional Neural Networks have become the standard for image classification tasks, however, these architectures are not invariant to translations of the input image. This lack of invariance is attributed to the use of ... -
Pairwise networks for feature ranking of a geomagnetic storm model
(South African Institute of Computer Scientists and Information Technologists, 2020)Feedforward neural networks provide the basis for complex regression models that produce accurate predictions in a variety of applications. However, they generally do not explicitly provide any information about the utility ... -
Using summary layers to probe neural network behaviour
(South African Institute of Computer Scientists and Information Technologists, 2020)No framework exists that can explain and predict the generalisation ability of deep neural networks in general circumstances. In fact, this question has not been answered for some of the least complicated of neural network ... -
Benign interpolation of noise in deep learning
(South African Institute of Computer Scientists and Information Technologists, 2020)The understanding of generalisation in machine learning is in a state of flux, in part due to the ability of deep learning models to interpolate noisy training data and still perform appropriately on out-of-sample data, ... -
Pre-interpolation loss behavior in neural networks
(Springer, 2020)When training neural networks as classifiers, it is common to observe an increase in average test loss while still maintaining or improving the overall classification accuracy on the same dataset. In spite of the ubiquity ... -
The South African directory enquiries (SADE) name corpus
(Springer, 2020)We present the design and development of a South African directory enquiries (DE) corpus. It contains audio and orthographic transcriptions of a wide range of South African names produced by first language speakers of four ...
