Bio-signal SNN Analytics

Spike-based intelligence for ECG and neuromorphic sensors

Event-driven ECG analysis pipeline implemented on neuromorphic hardware.

Abstract

Spiking neural networks (SNNs) provide a biologically plausible alternative to conventional deep learning by transmitting information through binary spikes. We harness this property to build ultra-low-power biosignal analytics pipelines that can run on neuromorphic chips and always-on wearable devices.

Research Highlights

  • Neuron-level realism: LIF and adaptive threshold neurons tuned with cardiology-inspired priors
  • Spike encoding: Temporal coding schemes that convert ECG and PPG signals into spike trains without losing diagnostic cues
  • Hybrid learning: Co-training with ANN teachers followed by spike-based fine-tuning on neuromorphic hardware
  • Interpretability: Mapping spike bursts back to physiological events for clinician review

Outcomes

  • Prototype ECG arrhythmia monitor consuming <1 mW on neuromorphic fabric
  • Tooling that auto-converts PyTorch models into event-driven graphs compatible with Intel Loihi and custom FPGA accelerators
  • Joint publications connecting computational neuroscience theory with deployable SNN analytics
