Deepfake <\/em>nedir?<\/b><\/p>\n

Yapay zek\u00e2\u00a0teknolojisiyle olu\u015fturulan deepfake<\/strong> <\/em>g\u00f6r\u00fcnt\u00fcleri<\/strong>, bireylerin a\u011f\u0131z ve y\u00fcz hareketlerinden yola \u00e7\u0131karak mimik ve hareketlerini alg\u0131l\u0131yor. Yapay zek\u00e2, elde edilen bu datalar\u0131 i\u015fleyerek karma\u015f\u0131k bir algoritma olu\u015fturuyor.\u00a0Bu algoritmaysa kendisine verilen g\u00f6rselleri t\u0131pk\u0131 mimikler ve tabirlerle g\u00fcncelleyip nihayetinde kusursuz denebilecek bir montajlama<\/strong> ortaya \u00e7\u0131k\u0131yor.<\/p>\n

G\u00fcn\u00fcm\u00fczde \u00fcnl\u00fc \u015fah\u0131slar\u0131 abs\u00fcrt sahnelere koyarak c\u00fcmb\u00fc\u015f hedefli kullan\u0131labilen bu teknoloji, bilhassa toplumsal medyada bir propaganda<\/strong> arac\u0131<\/strong> olabiliyor.

Facebook, Deepfake Detection Challenge i\u00e7in 10 milyon dolar harcad\u0131:<\/b><\/p>\n

<\/p>\n

Facebook, yar\u0131\u015f boyunca 3.500\u2019den fazla akt\u00f6r kulland\u0131 ve yakla\u015f\u0131k 10 milyon dolar<\/strong> harcad\u0131. Kaydedilen g\u00f6r\u00fcnt\u00fclerde ayr\u0131yeten rastgele bir algoritmay\u0131 zorlamak i\u00e7in birtak\u0131m dikkat da\u011f\u0131t\u0131c\u0131 de\u011fi\u015fiklikler de yap\u0131ld\u0131. Bu hususta konu\u015fan Facebook CTO\u2019su Mike Schroepfer<\/strong>, bu g\u00f6r\u00fcnt\u00fcleri \u00e7ekerken platformlarda payla\u015f\u0131lan g\u00f6r\u00fcnt\u00fc \u00e7e\u015fitlerine k\u0131ymet verdiklerini ve bu sebeple profesyonel \u015fartlarda \u00e7ekim yapmad\u0131klar\u0131n\u0131 s\u00f6yledi.<\/p>\n

Birinci etapta kullan\u0131lan algoritmalar<\/strong> \u00e7ok uygun sonu\u00e7lar vermedi lakin kimi ayarlardan sonra ge\u00e7ersiz i\u00e7eriklerin tespitinde %80\u2019in \u00fczerinde do\u011fruluk oran\u0131na ula\u015f\u0131ld\u0131. Bu noktada sonu\u00e7lar\u0131n varsay\u0131m etti\u011finden daha ba\u015far\u0131l\u0131 oldu\u011funu belirten Facebook CTO\u2019su Mike Schroepfer, kazanan modellerin %82 do\u011fruluk oran\u0131yla<\/strong> \u00e7al\u0131\u015ft\u0131\u011f\u0131n\u0131n da alt\u0131n\u0131 \u00e7izdi.<\/p>\n

Deepfake Detection Challenge\u2019da kazanan modeller, dal\u0131n geri kalan\u0131n\u0131 harekete ge\u00e7irmek i\u00e7in a\u00e7\u0131k kaynakl\u0131<\/strong> h\u00e2le getirilecek. Yani\u00a0herhangi bir yaz\u0131l\u0131m m\u00fchendisi koda fiyats\u0131z bir halde eri\u015febilecek.<\/p>\n
