Emulating nature鈥檚 perfect pursuit
The 成人大片鈥檚 machine learning expertise is also making waves in defence and other sectors, by enhancing autonomous-pursuit capabilities.
In an entirely novel approach, computer scientists, engineers and neuroscientists at the University have adapted dragonflies鈥 neuronal processes into a unique algorithm that emulates the insect鈥檚 phenomenal visual tracking capability.
Widely considered nature鈥檚 most effective predator, dragonflies are able to target, pursue and capture tiny flying prey in mid-air at speeds of up to 60 km/h鈥攅ven if that target attempts to disappear within a seething swarm鈥攚ith an incredible hit-rate of over 95 per cent.
Tested in various nature-mimicking virtual reality environments, our pursuit algorithm matches all other state-of-the-art pursuit algorithms鈥 accuracy, but achieves that while running up to 20 times faster,says Professor Ben Cazzolato.
鈥淪o it requires far less relative processing power.鈥
Mechanical engineering researchers at the University have also incorporated the algorithm in an autonomous robot that, in testing, has effectively and efficiently pursued targets in unstructured environments.
The interdisciplinary project is being led by neuroscientist , of the University of 鈥檚 Visual Physiology and Neurobotics Laboratory. It was Wiederman鈥檚 team that first identified how the dragonfly is able to focus on a single moving target and shut out all else鈥攁 remarkable find in itself.
鈥淲e recorded the activity of dragonfly neurons, and discovered the first identified neuron in any animal that exhibits an 鈥榓ttentional spotlight鈥,鈥 he explains. 鈥淚t鈥檚 able to select a single target amidst distracters. We also recorded from target-detecting neurons that predictively encode trajectory, enabling the dragonfly to estimate its target鈥檚 future location and ambush it.鈥
Keen to see how much further this translational path can take them, Wiederman and his team are now collaborating with Professor Reid to develop neurobiology-inspired machine-learning drone-tracking systems.
鈥淲e鈥檙e excited to further define the principles underlying neuronal processing. Translating them into advanced artificial vision systems could result in some incredibly effective autonomous robotics and drones, as well as neuronal prosthetics and many more applications.鈥
