Understanding the Functional Roles of Modelling Components in Spiking Neural Networks

no code implementations25 Mar 2024 Huifeng Yin, Hanle Zheng, Jiayi Mao, Siyuan Ding, Xing Liu, Mingkun Xu, Yifan Hu, Jing Pei, Lei Deng

By designing and evaluating several variants of the classic model, we systematically investigate the functional roles of key modelling components, leakage, reset, and recurrence, in leaky integrate-and-fire (LIF) based SNNs.

Bigeminal Priors Variational auto-encoder

no code implementations5 Oct 2020 Xuming Ran, Mingkun Xu, Qi Xu, Huihui Zhou, Quanying Liu

The likelihood-based generative models have been reported to be highly robust to the out-of-distribution (OOD) inputs and can be a detector by assuming that the model assigns higher likelihoods to the samples from the in-distribution (ID) dataset than an OOD dataset.
