New M-TTFS encoding boosts SNN energy efficiency for LLMs

Researchers have developed a new encoding method called Masked Time-to-First-Spike (M-TTFS) for spiking neural networks (SNNs) to improve energy efficiency in large language models. The M-TTFS encoding reassigns the silent state, which typically transmits no information, to represent the most common activation values, thereby reducing energy consumption related to data movement and weight reads. This approach was implemented in a spiking transformer model named Matterhorn, which achieved a 1.42 percentage point improvement on the GLUE benchmark and consumed 67% less energy compared to previous spiking transformers, while also showing consistent gains on LLaMA models.
