Fairness is a critical component of Trustworthy AI. In this paper, we focus on Machine Learning (ML) and the performance of model predictions when dealing with skin color. Unlike other sensitive attributes, the nature of skin color differs significantly. In computer vision, skin color is represented as tensor data rather than categorical values or single numerical points. However, much of the research on fairness across sensitive groups has focused on categorical features such as gender and race. This paper introduces a new technique for evaluating fairness in ML for image classification tasks, specifically without the use of annotation. To address the limitations of prior work, we handle tensor data, like skin color, without classifying it rigidly. Instead, we convert it into probability distributions and apply statistical distance measures. This novel approach allows us to capture fine-grained nuances in fairness both within and across what would traditionally be considered distinct groups. Additionally, we propose an innovative training method to mitigate the latent biases present in conventional skin tone categorization. This method leverages color distance estimates calculated through Bayesian regression with polynomial functions, ensuring a more nuanced and equitable treatment of skin color in ML models.
How English is YOUR hometown? Scientists reveal the place names that are the most 'archetypically English' - so, is yours on the list?
England is famous for its eccentric place names, from'Matching Tye' to'Fingringhoe' and'Upton Snodsbury'. But a new AI study now reveals the most English-sounding locations in the country – and they certainly conjure up images of cricket and afternoon tea. The study shows that'Harlington', a district of London, is the most archetypal English place name, along with'Widdington' in Essex and'Colworth' in West Sussex. It contrast, 'Anna', a settlement in Hampshire, is the least English-sounding, along with'Belgravia' in London and'Moira' in Leicestershire. Although AI was used to determine the language basis of English place names, not the meaning, the results could reveal more about the history of the locations.
Britain's most amazing shipwrecks REVEALED: Underwater monuments to the UK's rich maritime heritage
A whopping 350 years after it sank off the coast of Norfolk, authorities have revealed on Friday that HMS Gloucester has finally been found. The'outstanding' ship, which sank on May 6, 1682 after hitting the Norfolk sandbanks in the southern North Sea, was uncovered 28 miles off the coast of Great Yarmouth half-buried on the seabed. But HMS Gloucester is just one of thousands of shipwrecks that litter the British coast, the majority of which haven't been seen by the human eye for centuries. It's thought nearly 40,000 wrecks could be waiting to be found off the British coast, according to Historic England, providing snapshots of the UK's rich maritime heritage. But at least 90 are known to exist and experts have pinpointed their location, although many likely won't ever be brought to land and could disintegrate to nothing in the decades to come.
