  • The AI picked through the pictures taken by the drone pilots pixel by pixel, looking for anything that might look out of place on the mountainside. The software identified dozens of potential anomalies from a large number of photographs in a matter of hours.

    The selection, however, still needed to be whittled down with some human expertise.

    “The software could react to different things, like a piece of plastic garbage or an unusually coloured rock,” says Isola. “It can even hallucinate some things. So, we still had to narrow it down further by taking into consideration the path that Ivaldo, as a very skillful climber, might have used.”

    Interesting process. “AI” as a term gets so overused, but in this instance I think they’re really talking about image neural net processing.

    This other one mentioned sounds like just image processing:

    Other software that searches for unusually coloured pixels in natural landscapes – developed by the Lake District Search and Mountain Rescue Association in the UK – has been used to locate the body of a missing hillwalker in Glen Etive in the Scottish Highlands in 2023.

    Or is it ML, not AI?

    The key is to keep training the machine learning systems that power these algorithms to improve their accuracy in different types of terrain and conditions, says Tomasz Niedzielski, an expert in geoinformatics at the University of Wrocław and leader of the team that developed the SARUAV software.

    Overall interesting process but could be a lot more specific about the technology.


  • Yeah, that seems to be the article’s thesis, just a misleading title.

    What I’m proposing is neither global pessimism nor naïve faith. It’s local skepticism, or disciplined trust, which is precisely what science needs to improve itself. The history of science is indeed a graveyard of theories, but the fact that science keeps changing is a mark of its strength. It keeps changing because the world is complex and full of wonder. That isn’t a problem; it’s the engine that drives scientific progress
