L'EXPRESS - Feb 14 - Can an algorithm determine the success of a marriage? Can it predict the duration of a relation even before it begins? Dating apps are constantly improving, now incorporating a dose of AI. Tinder's "Elo Score" is now the subject of harsh criticism. This algorithm, inspired by the ranking of chess players, is matching people with lower score with people who also have a lower score. If someone with a higher score is interested in you, your initial score increases. Another matching technique is "Clustering" - which is based on matching you with people who are talking to people who are like you. "Dating apps don't know who your best match is so they rely on people who look like you to have a better idea. It's brilliant," says Mark Brooks, consultant and online dating expert. "Dating apps are still very young but are already delivering better results than hanging out in bars", he says.
