Low-resourced languages pose an interesting challenge for machine learning algorithms, representation, data collection and accessibility of machine learning in general. For African languages this challenge is even more consequential as it also coincides with the challenges of shaping the current revolution in artificial intelligence with the global landscape. In this talk I present our research work over the past few years, on working to make sure that African-language as well as local-language tasks count when we talk about the fourth industrial revolution. The work covers new approaches in modelling, data collection and community building in order to create the perfect environment for creativity, innovation and archiving across South African languages and beyond.

In a first for precision agriculture, University of Pretoria (UP) researchers, in association with collaborators from the Council for Scientific and Industrial Research (CSIR), have produced maps of smallholder farms in Gauteng that highlight maize plants in green and weeds in red. The maps were shared with farmers to enable them to pinpoint and eradicate weeds with more precision.
Farmers not only save time and money by cutting down the cost and effort required to manage weeds, but also limit the environmental impact of using harmful weed-killing chemicals by using satellite data and imagery.
This classification map shows the different types of plants in a crop field in various areas in Gauteng. The legend shows red for weeds, green for maize and yellow for mixed growth areas.
