SAFformer:Improving Spiking Transformer via Active Predictive Filtering

arXiv:2605.08270v2 Announce Type: replace-cross Abstract: Spiking Neural Networks (SNNs) offer notable advantages in biological plausibility and energy efficiency, making them promising candidates for building low-power Transformers. However, existing Spiking Transformers largely adhere to a passive reactive paradigm, which struggles to focus on task-relevant information and incurs substantial computational overhead when processing redundant visual data. To overcome this fundamental yet underexplored limitation, we propose SAFformer, a novel Spiking Transformer architecture based on an active

Why this matters
Why now

The continuous push for more efficient and brain-inspired AI architectures like Spiking Neural Networks (SNNs) is driven by the increasing computational demands of current AI models.

Why it’s important

This development addresses a critical limitation in Spiking Transformers, potentially enabling more energy-efficient and scalable AI systems, which is crucial for edge computing and sustainable AI infrastructure.

What changes

The introduction of active predictive filtering moves Spiking Transformers beyond a purely reactive paradigm, allowing for more intelligent processing and reduced computational overhead.
