Artificial neural networks have features difficult or impossible to explain to non-experts—certain aspects of how these networks function are not always fully understood by the experts.

Summary

This article by David Beer, writing for BBC, makes the following points:
  • Neural networks are at the heart of the most advanced artificial intelligence systems in use today.
  • They can learn and retrieve data through a process called 'associative memory'.
  • Pioneers of artificial neural networks weren't sure how these networks worked—and still aren't entirely sure today.
