Artificial intelligence and machine learning have reached new heights as scientists from Janelia and Google DeepMind collaborate to bring a virtual fruit fly to life. This groundbreaking achievement involved infusing a computerized insect with sophisticated AI capabilities, allowing it to emulate the natural movements of a real fruit fly.
The virtual fly represents the most realistic simulation of a fruit fly that has been developed thus far. The remarkable accuracy of this creation can be attributed to its unique combination of an anatomically precise model of the fly’s outer skeleton, a high-speed physics simulator, and an artificial neural network that was trained using real fly behavior data. Through this training process, the network has gained the ability to control the fly’s motions, enabling it to walk and fly in a manner indistinguishable from its living counterpart.
According to Roman Vaxenburg, the lead researcher of the project from the Turaga Lab at Janelia, the artificial neural network functions as a miniature brain for the virtual fly, dictating its movements and actions. By analyzing and replicating the behavioral patterns of actual flies, the network has become proficient in mimicking their complex motions.
This initial version of the virtual fly is expected to undergo further enhancements to achieve an even higher degree of lifelikeness. The team plans to integrate additional anatomical features, sensory capabilities, and a genuine neural network into future models. The ultimate aim is to establish a series of realistic animal models based on this open-source framework, not only for their own research purposes but also for the wider scientific community.
By utilizing these virtual models of animals, scientists can gain deeper insights into the intricate relationship between the nervous system, body structure, and environment in controlling various behaviors. While studies conducted with live animals have contributed significantly to our understanding, virtual simulations offer a novel perspective by elucidating the interactions and influences of unmeasurable factors, such as the forces exerted on the body during flight.
Janelia Group Leader Srinivas Turaga, a senior scientist involved in the project, emphasizes that the physics simulation embedded within the virtual fly’s design plays a crucial role in comprehending the mechanisms behind the translation of neural commands into physical actions. The shape of the body and its interactions with the surrounding world significantly impact the execution of these commands. Consequently, the intricate physics simulation encapsulated within the virtual model provides valuable insights into these fundamental processes.
The virtual fly’s body is composed of 67 intricately connected parts, interlinked by 66 joints, resulting in a remarkable 102 degrees of freedom. This structural complexity enables the virtual fly to replicate natural movements with a remarkable level of accuracy.
This significant advancement in virtual insect creation marks a pivotal moment in the progressive integration of artificial intelligence and biological simulation. The combination of detailed anatomical modeling, sophisticated physics simulation, and machine learning has unlocked new avenues of research and experimentation, paving the way for a deeper understanding of animal behavior and cognition. Through the development of increasingly lifelike virtual models, scientists hope to uncover the intricate workings of various species and unravel the complexities of their interactions with the environment.
