Developing an AI network can help scholars restore ancient Greek texts. Researchers at University of Oxford have recruited new deep learning techniques to decipher symbols of ancient languages.

The research team says there are many artifacts featuring important historical symbols and inscriptions that erode with time, noting that the clear inscriptions that archaeologists can read and understand are few.

In a test, where the AI attempted to fill the gaps in 2,949 damaged inscriptions, human experts managed to explain 30 percent of unclear symbols, whereas the network took two hours to decipher 50 inscriptions, reported the New Scientist website.

The team said the new network named "Pythia" is able to provide 20 different predictions to explain each eroded inscription, leaving the selection of the suitable hypothesis that correspond to the context of the ancient inscriptions to archaeologists.

In addition to providing various options, Pythia evaluates the reliability of each option or hypothesis it offers to archaeologists to help them reach the correct one.

"Pythia is the first electronic model used to restore ancient archaeological inscriptions by deciphering the eroded letters through deep learning networks," the study team wrote.

An Australian student missing for two weeks near the country's tallest mountain was found on Wednesday, after surviving by foraging for berries, drinking water from a creek and finding two muesli bars left behind by other hikers, police said.

Hadi Nazari, a 23-year-old university student from Melbourne, went missing from his group of friends on December 26 in the Kosciuszko National Park.

Nazari was found on Wednesday afternoon by a group of hikers who alerted the authorities, police in the state of New South Wales said.

“This is the fourteenth day we've been looking for him and for him to come out and be in such good spirits and in such great condition, it’s incredible," NSW Police Inspector Josh Broadfoot said.

The student was in "really good spirits" with no significant injuries, he added.

More than 300 people had searched for Nazari across rugged bushland, police said. The national park is home to the 2,228 meter (7,310 foot) Mount Kosciuszko.
