arXiv:2606.13016v1 Announce Type: new Abstract: Spiking neural networks (SNNs) are promising for energy-efficient inference, and time-to-first-spike (TTFS) coding is especially attractive because each neuron fires at most once. In practice, however, this benefit is often reduced by the cost of computing a temporal decay term and multiplying it by the synaptic weight. We address this issue by turning a physical hardware "bug," the natural signal decay in optoelectronic devices, into the main computation of TTFS, named Otters++. Specifically, we use the measured decay of a custom In$_2$O$_3$ opt
The continuous push for more energy-efficient AI hardware and the maturation of optoelectronic technologies are converging to enable novel solutions like this for spiking neural networks.
This development proposes a method to significantly reduce the energy consumption of spiking neural networks, making AI inference more sustainable and scalable.
By leveraging physical properties of optoelectronic devices for computation, this approach alters how energy efficiency in SNNs is conceived and implemented, potentially opening new hardware design paradigms.

More energy-efficient AI models can be deployed across a wider range of applications, especially at the edge.
Achieving orders of magnitude energy reduction could reduce the operational cost of large AI models, fostering further growth and development.
Lower energy consumption could mitigate some concerns regarding the environmental impact and energy bottleneck of rapidly expanding AI infrastructure.
