Mientras que costosas pruebas gen\u00e9ticas pueden revelar c\u00f3mo se desgasta el ADN con el tiempo, FaceAge promete ofrecer informaci\u00f3n utilizando solo una selfie.<\/p>\n\n\n\n<p>El modelo fue entrenado con 58.851 retratos de adultos presumiblemente saludables mayores de 60 a\u00f1os, extra\u00eddos de conjuntos de datos p\u00fablicos.<\/p>\n\n\n\n<p>Luego fue probado en 6.196 pacientes con c\u00e1ncer tratados en Estados Unidos y los Pa\u00edses Bajos, utilizando fotos tomadas justo antes de la radioterapia. Los pacientes con tumores malignos parec\u00edan en promedio 4,79 a\u00f1os mayores biol\u00f3gicamente que su edad cronol\u00f3gica.<\/p>\n\n\n\n<p>Entre los pacientes con c\u00e1ncer, una puntuaci\u00f3n FaceAge m\u00e1s alta predijo fuertemente una peor supervivencia \u2013incluso despu\u00e9s de considerar la edad real, sexo y tipo de tumor\u2013 y el riesgo aument\u00f3 abruptamente para cualquiera cuya lectura biol\u00f3gica superara los 85.<\/p>\n\n\n\n<p>Curiosamente, FaceAge parece ponderar los signos del envejecimiento de manera diferente a los humanos. Por ejemplo, tener canas o calvicie importa menos que los cambios sutiles en el tono muscular facial.<\/p>\n\n\n\n<p>FaceAge tambi\u00e9n mejor\u00f3 la precisi\u00f3n de los m\u00e9dicos. Se pidi\u00f3 a ocho m\u00e9dicos que examinaran fotograf\u00edas de pacientes con c\u00e1ncer terminal y adivinaran qui\u00e9n morir\u00eda en seis meses. Su tasa de \u00e9xito apenas super\u00f3 el azar; con los datos de FaceAge disponibles, las predicciones mejoraron notablemente.<\/p>\n\n\n\n<p>El modelo incluso confirm\u00f3 un meme favorito de internet, estimando la edad biol\u00f3gica del actor Paul Rudd en 43 a\u00f1os en una foto tomada cuando ten\u00eda 50.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" src=\"https:\/\/static.dw.com\/image\/55544675_906.jpg\" alt=\"Los investigadores demostraron que pacientes con c\u00e1ncer aparentaban casi cinco a\u00f1os m\u00e1s que su edad cronol\u00f3gica seg\u00fan el an\u00e1lisis de inteligencia artificial.\"\/><figcaption class=\"wp-element-caption\">Los investigadores demostraron que pacientes con c\u00e1ncer aparentaban casi cinco a\u00f1os m\u00e1s que su edad cronol\u00f3gica seg\u00fan el an\u00e1lisis de inteligencia artificial.<small>Imagen: Axel Bueckert\/Zoonar\/picture-alliance<\/small><\/figcaption><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\"><strong>Avances en IA m\u00e9dica: precisi\u00f3n y sesgos potenciales<\/strong><\/h2>\n\n\n\n<p>Las herramientas de IA han enfrentado escrutinio por brindar un servicio deficiente a personas no blancas. Mak dijo que comprobaciones preliminares no revelaron sesgo racial significativo en las predicciones de FaceAge, pero el grupo est\u00e1 entrenando un modelo de segunda generaci\u00f3n con 20.000 pacientes.<\/p>\n\n\n\n<p>Tambi\u00e9n est\u00e1n investigando c\u00f3mo factores como el maquillaje, la cirug\u00eda est\u00e9tica o las variaciones de iluminaci\u00f3n podr\u00edan enga\u00f1ar al sistema.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Dilemas \u00e9ticos: privacidad y aplicaciones futuras<\/strong><\/h2>\n\n\n\n<p>Los debates \u00e9ticos son importantes.

Enterarse de que tu cuerpo es biol\u00f3gicamente mayor de lo que pensabas puede impulsar cambios saludables o sembrar ansiedad.<\/p>\n\n\n\n<p>Los investigadores est\u00e1n planeando abrir un portal p\u00fablico de FaceAge donde las personas puedan subir sus propias fotos para inscribirse en un estudio de investigaci\u00f3n para validar a\u00fan m\u00e1s el algoritmo. Pueden seguir versiones comerciales dirigidas a m\u00e9dicos, pero solo despu\u00e9s de m\u00e1s validaci\u00f3n.<\/p>\n\n\n\n<p><em>FEW (AFP,\u00a0The Lancet Digital Health)<\/em><\/p>\n\n\n\n<hr
