(Elsevier, 2025-01)The process of training feedforward neural networks (FFNNs) can benefit from an automated process where the best heuristic to train the network is sought out automatically by means of a high-level probabilistic-based ...
-
(Institute of Electrical and Electronics Engineers, 2024-09)Social media platforms play a significant role in analyzing customer perceptions of financial products and services in today’s culture. These platforms facilitate the immediate and in-depth sharing of thoughts and ...
-
(University of Pretoria, 2023-06)The information age has been a critical driver in the impressive advancement of Natural Language Processing (NLP) applications in recent years. The benefits of these applications have been prominent in populations with ...
-
(University of Pretoria, 2024-02)The human language is cryptic since words can be interpreted differently based upon the context within which they occur. The exact meaning of a particular word in its context might be trivial for humans who are generally ...
-
(University of Pretoria, 2023-11)Understanding public sentiment is vital for political parties in order for them to be able to structure their election campaigns around voter expectations. The study focuses on unsupervised learning to assess the variation ...
-
(University of Pretoria, 2024)In many Sub-Saharan countries, the advancement of public transport is frequently overshadowed by more prioritised sectors, highlighting the need for innovative approaches to enhance both the Quality of Service (QoS) and ...
-
(University of Pretoria, 2021)The judicial system is the central pillar of law and order across the world. It is re- sponsible for maintaining order amongst citizens and also solving litigations that arise. Although this system has worked quite well, ...
-
(University of Pretoria, 2024-04)Social media creates an echo chamber effect that is closely related to social movement theory, which aims to mobilise people to change society. In South Africa, there has been an increase in protests that appear to have ...
-
(Cell Press, 2023-07)As large AI models demonstrate increasingly human-like performance on complex tasks, many scientists are developing or adapting these models to empower their research and applications. Because of the substantial costs ...
-
(University of Pretoria, 2023-12-08)The schedulability analysis of real-time systems is challenged by the state space complexity of such systems. It is difficult to develop concrete state space models that can be used to verify the schedulability of real-time ...
-
(Elsevier, 2024-12)Low-light image enhancement (LLIE) techniques attempt to increase the visibility of images captured in low-light scenarios. However, as a result of enhancement, a variety of image degradations such as noise and color bias ...
-
(Springer, 2023-03-09)The South African Local Government (SALG) uses the tendering system to procure goods and services. Some of these tendering projects are aimed at promoting socio-economic and industrial policies. Hence, the tendering system ...
-
(Learning Information Networking and Knowledge (LINK) Centre, Graduate School of Public and Development, 2023)The narratives shared on social media during a health crisis such as COVID-19 reflect public perceptions of the crisis. This article provides findings from a study of the perceptions of South African citizens regarding ...
-
(University of Pretoria, 2024-03)Traditionally, search techniques explore a single space, namely the solution space, to find a solution to a discrete optimisation problem. However, as the field has developed, the effectiveness of working in alternative ...
-
(Springer, 2024-06)The use of genetic algorithms (GAs) to evolve neural network (NN) weights has risen in popularity in recent years, particularly when used together with gradient descent as a mutation operator. However, crossover operators ...
-
(Springer, 2024-03)Neural architecture search (NAS) is a rapidly growing field which focuses on the automated design of neural network architectures. Genetic algorithms (GAs) have been predominantly used for evolving neural network architectures. ...
-
(Easychair, 2023)Automated hate speech detection is important to protecting people’s dignity, online experiences, and physical safety in Society 5.0. Transformers are sophisticated pre-trained language models that can be fine-tuned for ...
-
(Elsevier, 2024-07)Streamed data classification problems (SDCPs) require classifiers to not just find the optimal decision boundaries that describe the relationships within a data stream, but also to adapt to changes in the decision boundaries ...
-
(Elsevier, 2023-11)Asset Liability Management (ALM) is an essential risk management technique in Quantitative Finance and Actuarial Science. It aims to maximise a risk-taker’s ability to fulfil future liabilities. ALM is especially critical in ...
-
(MDPI, 2023-04-24)The objective of this paper was to scope the challenges associated with data-sharing governance for machine learning applications in education research (MLER) within the South African context. Machine learning applications ...
