Neuromorphic Computing Paradigms Enhance Robustness through Spiking Neural Networks

Experimental results on datasets such as CIFAR-10 show that the proposed SNN-based methods significantly outperform conventional ANNs in adversarial settings, achieving up to twice the robustness. At the same time, the model maintains high energy efficiency, making it suitable for real-world safety-critical and resource-constrained applications.

CaRe-BN: Precise Moving Statistics for Stabilizing Spiking Neural Networks in Reinforcement Learning

Extensive evaluations across discrete action spaces (Atari benchmarks) and continuous control tasks (MuJoCo suite) demonstrate that CaRe-BN significantly resolves the issue of imprecise moving statistics. SNN-based agents equipped with CaRe-BN consistently achieved higher exploration returns, converged faster, and exhibited significantly lower variance compared to standard SNNs. Notably, when paired with the TD3 algorithm, CaRe-BN allowed simple SNNs to surpass the performance of traditional ANN-based RL agents by an average of 5.9%, establishing a new state-of-the-art normalization strategy that bridges the gap between neuromorphic efficiency and high-performance RL.

USP-Gaussian: Unifying Spike-based Image Reconstruction, Pose Correction and Gaussian Splatting

Extensive experiments on both synthetic and real-world datasets show that USP-Gaussian consistently outperforms prior spike-based reconstruction methods. On the synthetic benchmark, the paper reports an average performance of 27.903 PSNR / 0.843 SSIM / 0.217 LPIPS, surpassing the main baseline SpikeGS, which achieves 27.196 / 0.832 / 0.244. In particular, on the Outdoorpool scene, USP-Gaussian reaches 30.142 dB PSNR, which is the best result in the table. These results verify that unified optimization substantially alleviates the error accumulation problem in cascaded pipelines.
