ML algorithm judges ‘fairness’ in AI results

Artificial intelligence algorithms can be embedded with fairness notions, according to Queen’s University Belfast, where such a machine learning (ML) algorithm has been developed. This is not the first time a fairness algorithm has been created, explained Queen’s researcher Dr Deepak Padmanabhan, but it is the first time that an algorithm can handle more than ...
