Spiking Neural Networks (SNNs) have the potential to revolutionize the field of artificial intelligence by emulating neural dynamics and capturing temporal information through event-based computations, enabling more brain-like and energy-efficient computations. The brain's remarkable ability is largely attributed to its large-scale network and massive interconnectedness. It’s crucial to push the boundaries to construct larger-scale SNNs to unlock their potential on a grander level, which could open up possibilities for groundbreaking advancements in brain-inspired artificial intelligence, neuromorphic computing, and novel applications in various domains such as computer vision, robotics, cognitive computing, and brain-machine interfaces.
To advance the research on large-scale Deep SNNs, we focus on the following key issues.
First, scaling up SNNs to large-scale networks encounters challenges in both algorithms and architectures, due to the complexity arising from their temporal dynamics and spike-based computation. Overcoming problems like gradient explosion/vanishing and performance degradation and designing scalable architectures like transformer to push the field to new frontiers are essential in constructing large-scale SNNs.
Second, studying SNNs is motivated by their resemblance to biological neural systems. However, existing biological algorithms, such as STDP, are unsupervised and struggle to converge in large-scale SNNs. Furthermore, mainstream rate-based training methods fail to exploit temporal dynamics. These issues call for bio-inspired algorithms incorporating advanced neuron models, neural plasticity, and temporal dynamics.
Third, energy-efficiency is another motivation of deep SNNs. Most deep SNNs are not purely event-driven, and there is a lack of frameworks and computing chips for efficient training of large-scale event-driven SNNs. Given the growing demand for energy-efficient computing, we encourage contributions in pure event-driven models, low-power hardware designs, model compression, and efficient computing frameworks to maximize energy-efficiency without compromising performance.
Finally, the real-world applications of large-scale SNNs should be highlighted, as they offer immense potential for enhancing performance and efficiency. The integration of neuromorphic hardware, such as Dynamic Vision Sensors, further enhances this potential by providing event-based, asynchronous, and adaptive sensory information that’s well-suited for deep SNNs. These applications include, but are not limited to: robotics, autonomous vehicles, natural language processing, computer vision, speech recognition, medical diagnosis, and AI for brain systems.
In summary, exploring the potential of large-scale SNNs requires addressing challenges in scaling up, developing specialized brain-inspired algorithms, energy-efficient computing and real-world applications.
