Made from artificial intelligence. None of these people exists

Developments in artificial intelligence are moving at an impressive rate, so much so that it's often hard to follow. The machines have now been able to produce incredibly plausible photographs of people, but they have never been on Earth.

These realistic but non-existent faces in the photo above are the work of researchers from Nvidia. In their work on artificial intelligence. which they presented publicly last week, describe the modification of the artκτονικής GAN (Generative Adversarial Network) ώστε να δημιουργήσουν αυτές τις πλασματικές . Take a better look. If you didn't know they were fake, could you tell?

In the image above you can see what progress is within four years of entering the artificial intelligence into the image. The rough black and white faces on the left are from 2014 and were published in one paper, which then pioneered the AI ​​tool with the GAN (Generative Adversarial Network). On the right you see a similar task that was published this month, in which the same method (GAN) was used, but the difference is clearly huge of the image.

Αυτό που είναι ιδιαίτερα ενδιαφέρον είναι ότι αυτά τα ψεύτικα πρόσωπα μπορούν επίσης να προσαρμοστούν εύκολα. Οι μηχανικοί της Nvidia ενσωμάτωσαν στη δουλειά τους μια μέθοδο γνωστή ως style transfer (μεταφορά στυλ), στην οποία τα χαρακτηριστικά μιας εικόνας αναμειγνύονται με μια άλλη. Μπορεί να αναγνωρίσετε τον όρο από διάφορα φίλτρα εικόνας που είναι δημοφιλή τα τελευταία χρόνια σε εφαρμογές όπως το Prisma και το , γεγονός που μπορεί να κάνει τους εαυτούς σας να μοιάζουν με μια ιμπρεσιονιστική ζωγραφική ή με ένα έργο κυβιστικής τέχνης.

Η του style transfer στα πρόσωπα, επέτρεψε στους της Nvidia να τα προσαρμόσουν σε εντυπωσιακό βαθμό. Στο παρακάτω πλέγμα, μπορείτε να δείτε την εξέλιξη. Παίρνοντας μια εικόνα ως πηγή (source) ενός πραγματικού προσώπου (η πάνω πάνω σειρά) και αναμιγνύωντας τα με άλλα ενός διαφορετικού πραγματικού προσώπου (δεξιά στήλη) δείτε το αποτέλεσμα που παράγεται. Χαρακτηριστικά όπως το χρώμα του δέρματος και των μαλλιών κλπ αναμειγνύονται μαζί, δημιουργώντας ένα εντελώς νέο πρόσωπο.

Of course, the ability to create realistic faces through artificial intelligence raises troubling questions. These tools could be used for disinformation and propaganda and could disrupt public trust in visual evidence. A fact that could damage the judicial system as well as politics. Especially in today's era when fake news has managed to fool even the public agencies.

Όσο αναφορά την δυσκολία ς και την πιστότητα: Οι ερευνητές της Nvidia χρειάστηκαν μια εβδομάδα για να εκπαιδεύσουν το μοντέλο τους σε ένα μηχάνημα με οκτώ GPU Tesla, ώστε να δημιουργήσουν αυτά τα πρόσωπα. There are also indications which we can look for to find fake photos. Hair, for example, is very difficult to forge. They often look like they are painted with a brush or very blurred. However, Nvidia's work shows how fast the development of artificial intelligence in this field is, and at this rate they will not be slow to create algorithms that can prevent such mistakes.

It is obvious that there will be a battle in the next few decades about the identity of an image, between fake creatures of artificial intelligence and security researchers. And at this time, artificial intelligence has the lead. The Best Technology Site in Greecefgns
