Artificial intelligence helps reveal how people process abstract thought: Study of deep neural networks suggests knowledge comes via sensory experience

"As we rely more and more on these systems, it is important to know how they work and why," said Cameron Buckner, assistant professor of philosophy and author of a paper exploring the topic published in the journal Synthese. Better understanding how the systems work, in turn, led him to insights into the nature of human learning. Philosophers have debated the origins of human knowledge since the days of Plato -- is it innate, based on logic, or does knowledge come from sensory experience in the world? Deep Convolutional Neural Networks, or DCNNs, suggest human knowledge stems from experience, a school of thought known as empiricism, Buckner concluded. These neural networks -- multi-layered artificial neural networks, with nodes replicating how neurons process and pass along information in the brain -- demonstrate how abstract knowledge is acquired, he said, making the networks a useful tool for fields including neuroscience and psychology.
