Elevating data analytics and machine learning in South Africa: Advancing capacity and statistics and machine learning through focused and collaborative research initiatives
Machine Learning in support of Computational and Theoretical Sciences
The goal of the programme is to strengthen machine learning (ML) collaboration in NITheCS in two ways:
ML research: development of new, specialised machine learning techniques.
ML as a tool: applying machine learning for scientific modelling applications.

Knowledge Discovery in Time Series Data
Machine learning techniques play an increasing role in assisting scientists and engineers in knowledge discovery: obtaining novel information from large, possibly complex data sets. Many practically important tasks, such as weather prediction, financial forecasting, or speech processing, are modelled using time series information. Knowledge discovery in time series data is an active field of research, with techniques such as feature attribution used to gain new insights into the underlying processes being modelled.
Machine Learning Forum
The programme aims to grow a forum for cross-cutting projects executed in other NITheCS focus areas, where those projects rely on machine learning expertise.
The programme is open to all NITheCS Associates who currently work in machine learning, or are interested in ML approaches in their research.
