First Black woman to receive PhD in Applied Data Science tackles AI’s prejudice
Artificial intelligence (AI) represents one of the most prominent milestones within the science and technology fields. AI’s effectiveness lies in its ability to harvest and process huge amounts of data, make accurate predictions, solve complex challenges across different fields and also automate variety of mostly routine functions.
But as with any technological novelties, AI’s algorithms have shortcomings include perpetuation and reinforcement of entrenched societal stereotypes, inequalities and discrimination, bias and discrimination.
Reason for her Research
Dr Khensani Xivuri, the first Black female recipient of a PhD in Applied Data Science from the University of Johannesburg (UJ), focuses her research on development a procedural model, aimed at identifying and mitigating bias in AI models prior to implementation.
She says her research was driven by scenarios whereby an algorithm, based on flawed assumptions, may unfairly prejudice individuals on the basis of their gender or race; being unjustly denied a loan for a car or home or even facing higher interest rates due to faulty credit scoring.
Addressing AI models’ bias
“A lot of bias has been detected from these AI models and this has had a huge impact on society. My research focused on creating a process model to detect and address bias in AI models before their deployment. The model stresses the importance of involving society throughout the development process,” Dr Xivuri says. Her findings uncovered limited gender and social diversity in AI teams and Dr Xivuri opines that adding these can lead to bias in these models; certain groups may be under-represented or misrepresented, ultimately affecting the fairness of AI models and their impact on society.
Dr Xivuri – An Invaluable Asset
Dr Stella Bvuma, UJ’s director at the School of Consumer Intelligence and Information Systems at UJ, says Dr Xivuri’s accomplishment surpasses mere academic triumph; it embodies the essence of shattering barriers and paving the way for forthcoming generations. “In an era increasingly reliant on data and technology, experts such as Khensani serve as invaluable assets, adept at navigating the digital terrain with confidence and profound knowledge
The Force Behind her Success
Dr Xivuri, from the village of Peninghotsa, Malamulele in the Limpopo Province, attributes her success to her father’s unfailing support. She says her father routinely shared his pearls of wisdom with children and he always quoted his favourite Xitsonga saying: “unga sunguli xilo unga xi hetisi,” –translated in English, it means don’t start something you cannot finish. It emphasises the principle of commitment and perseverance from start to finish.
Giving up was simply not an option. She says she had to be disciplined and also had to work to find a delicate balance between her academic and employment demands.
Igniting Inspiration for STEM
Dr Xivuri is passionate about breaking barriers hindering women to enter STEM fields. “I believe women should embrace STEM careers as thrilling adventures. We must encourage more women to make their mark and ignite inspiration for the next generation in this field. The greater our presence in STEM, the more empowering it becomes for future generations of women. We need leaders committed to uplifting others as they progress.”
“Her triumph serves as a poignant reminder that talent knows no bounds and that with dedication and perseverance, every aspiration is within reach. Dr Xivuri’s journey stands as a guiding light, propelling us closer to a future characterised by brightness and inclusivity with every milestone conquered,” Dr Bvuma added.
This female pioneer says she hopes her success will serve as an inspiration to young girls who grew up under similar trying circumstances as hers. In addition, her journey serves as a testament to the power of resilience and the pursuit of one’s dreams against all odds.
