fuzzy logic system to form a Hybrid Expert System (HES) reaping the advantages of various techniques. It is a milestone for randomisation to be introduced at tree growth and forest creation. The local prediction accuracies on the leaves are used to select a subset of the test data for actual predictions. The ensemble combines trees and gives a better performance than the individually best performing tree.
By fusing tree-based machine learning with a random order the scientists believe that the symptoms of an ailment from a patient serve as the input vector to diagnose the ailment with the AI model. “There is an urgent need for the development of easily implemented, automatic and effective screening methods. This will help health professionals and inform individuals whether or not they should pursue a formal clinical diagnosis,” says the UJ team.
The good news for South Africa: With the knowledge and experience acquired in the above- mentioned and other recent publications, the UJ team has already started a collaborative project with Charlotte Maxeke Academic Hospital for AI based diagnosis of breast cancer of local patients. UJ is looking to expand this kind of AI work to a much wider scope by providing significant funding to address more common diseases.
The Fourth Industrial Revolution (4IR) will have a greater impact on the evolution of global healthcare in the decades to come and nanotechnology would be a major contributor to this. According to Samuel Oluwatobi Oluwafemi, a Professor in Applied Chemistry at the University of Johannesburg, biotechnologists together with nanotechnologists can discover/fabricate new generation medicine or even a robot programmed to target cancer cells. “The ultimate goal of the research is to go beyond the laboratory experimental work, to answer questions such as appropriate dosage, delivery system and exposure times that maximise clinical effectiveness while minimising side effects, to increase the clinical acceptance of this technology,” said Prof Samuel Oluwatobi Oluwafemi when he delivered his professorial inaugural address titled ‘How small things can make a big world a better place: The significance of Nano in a Macro world’. He argued that the outcome of this research will provide renewed hope for patients diagnosed with cancer.
