Insights from studying the bee brain are informing advancements in artificial intelligence.

Despite its small size, a bee’s brain exhibits the ability for impressive communication, problem-solving, and metacognition. “If we study intelligence not just in humans but in other living things, potentially in machines, we can tidy up the definition of what intelligence is and where we draw the boundary on what’s intelligent and what’s not," says Dr. Andrew Barron, a leading expert in animal cognition, specializing in the honeybee.

Dr. Barron and his colleagues have built a computational model of the bee brain in the virtual world. The model has become a dynamic system in which data can run through the computational bee brain and the output can then be analyzed. Information gleaned from the examination of the simply structured minds of invertebrates can lead to accurate hypotheses for more highly structured and diverse intelligences. The simplicity of the honeybee brain has made it accessible for thorough study. Knowledge that is being gained from this research is expected to lead to deeper understanding of more complex thinking systems.

Even though the honeybee brain is made up of only 1 million neurons (a human brain has more than 80 billion) it is still far more complex than the current state of artificial intelligence. By examining the throughput from the model of the bee brain, Dr. James Marshall is beginning to apply this knowledge to the future of autonomous drone flight.

Safety and reliability are key concerns in robotics moving forward. The advanced study and deep understanding of the bee brain make it a prudent modeling candidate for advanced artificial intelligences. Findings from the bee brain model are being applied to current and future challenges facing AI-equipped robotics and machine learning technologies which will increasingly assist humans in solving some of the most complex problems we face as a species.

Highlights from this installment of our award-winning “Stories of Impact” video series:

  • The concept I don’t know is an example of metacognition. Honeybees have shown that they understand when they don’t have enough information to make a decision. Bees have expressed I don’t know in experiments by exiting an experiment rather than making a choice.
  • Honeybees utilize a symbolic dance language. When they encounter a potent nectar they go into a shaking walk that communicates the location and subjective evaluation of the experience to others in the hive.
  • Bees are very reliable, and amazing navigators across very large distances. Collision avoidance learned from the study of the computational bee brain could lead to advanced, autonomous drones to aid in a variety of human endeavors.
