Using the bee visual recognition system as model artificial intelligence

So who is smarter than a fifth grader? Maybe a bee.

Using the Pavolvian behavioral rewards system, researchers  trained different groups of free flying bees to choose the “right” answer by rewarding them with sugar water. If they made an incorrect choice, the bees were punished with a bitter tasting solution. Faces were presented on a vertical screen and bees slowly learned to fly to the correct target faces. Over the course of a day a bee brain learned a complex task, and then when tested in non-rewarded tests (to totally excluded cues like olfaction) only bees that had experience multiple views (e.g. faces at both 0° and 60°) were able to solve a novel rotational angle of 30°.

Dr Dyer said the discovery helps to answer a fundamental question about how brains solve complex image rotational problems by either image averaging or mentally rotating previously learnt views.

“Bee brains clearly use image interpolation to solve the problem. In other words, bees that had learnt what a particular face looked like from two different viewpoints could then recognise a novel view of this target face. However, bees that had only learnt a single view could not recognise novel views,” Dr Dyer said.

The study, performed over two years in Australia and Germany by Dr Dyer with the support of the US Air Force Office of Scientific Research (AFOSR), and Dr Quoc Vuong from Newcastle University UK, was published in the science journal PLoS ONE.

“The relationships between different components of the object often dramatically change when viewed from different angles but it is amazing to find the bees’ brains have evolved clever mechanisms for problem solving which may help develop improved models for AI face recognition systems,” Dr Dyer said. This research from Monash University bee researcher Adrian Dyer could lead to improved artificial intelligence systems and computer programs for facial recognition.

Save the bees take care of the environment.
