As Machine Learning advances, how will we know that these systems are making the right decisions? In this story from the Fraunhofer Heinrich Hertz Institute, researchers are looking at the learning strategies of today’s Ai systems. “We were very surprised by just how broad the range of learned problem-solving strategies is. Even modern AI systems have not always found a meaningful approach, at least not from a human perspective, instead sometimes adopting what we call ‘Clever Hans’ strategies.”
