Sparse Gradient Training in Spiking Neural Networks: Accuracy and Latency on Tabular Data Benchmarks

Abstract

Abstract: The brain-inspired Spiking neural networks (SNN) claim to present advantages for visual classification tasks in terms of energy efficiency and inherent robustness. In this work, we explore the impact on network inter-layer sparsity through neural coding schemes and the intrinsic structural parameters of Leaky Integrate-and-Fire (LIF) neurons, which can be a candidate metric for performance evaluation. Towards this, we perform a comparative study of four critical neural coding schemes: rate coding (poisson coding), latency coding, phase coding, and direct coding, as well as 6 LIF neuron intrins

Research Question

How does the integration of sparse gradient training in Spiking Neural Networks compare to standard surrogate gradient methods in terms of accuracy and inference latency on tabular data benchmarks like MLP-1M or OpenML?

Verification Level

Descriptive public verification status only; aggregate claim counts are public, but individual claim records are not exposed here.

Truth-Engine Gate Verdict

This record has not completed Gate 2 of the verification pipeline (a type-checked Lean4 proof for mathematical claims, or a sealed-sandbox reproduction for empirical claims). It is a literature synthesis only. VERIFIED requires an attached reproducible artifact (Lean4 proof source, or repro script and results) before this status can be set; it is not derived from review score or claim count.

Quality Tier

Descriptive public triage only; this tier does not alter current publication or DOI behavior.

Quality Dimensions

Automated triage signals derived from public fields; not human peer review or independent validation.

Correction Record

Public corrections are additive records. Current status does not claim the synthesis is error-free.
