Mott devi.es, featuri.g.low hardware cost and hi.0} energ. effi.i.ncy, have been demonstrated as a key osci.latory element i. arti.i.i.l neurons to enable spi.i.g.neural networks(SNNs) such as conversi.nbased SNNs(CSNNs). However, there wi.l be i.evi.ably non-i.eal fluctuati.n i. the osci.lati.n behavi.r,causi.g.the accuracy deg.adati.n of networks. i. thi. paper, we i.vesti.0}te the Mott neuronal osci.lati.n fluctuati.n(NOF) throug. experi.ents and modeli.g. The results show that the NOF phenomenon conforms to g.ussi.n di.tri.uti.n and ori.0}nates from thermal fluctuati.n i.duced swi.chi.g.voltag. vari.ti.ns. We construct a two-layer CSNN for i.ag. recog.i.i.n tasks to study the NOF effect and propose the acti.ati.n functi.n boundary(AFB) method to streng.hen the stabi.i.y of the network. The results i.di.ate that AFB can i.prove the accuracy of CSNN by up to 15.5% by ti.0}teni.g.output di.tri.uti.n.

新时期国家大力提倡学科交叉,加快“双一流”建设目标,着重打破传统学科间壁垒,探索跨院系、跨学科、跨专业交叉培养拔尖创新人才,加快学科协同交叉融合,这对提出并解决交叉学科难题具有重要意义。然而,真正的多学科、交叉学科及跨学科方法并不可能通过制度性的强制要求而孵化产生,且在现有实践中很难实现真正的交叉学科。那么,交叉学科研究是否必要?如何促进交叉学科发展,存在哪些机遇与挑战,在学科交叉发展中又存在哪些制度性发展陷阱?针对以上问题,华东师范大学国际与比较教育研究所张丹副教授与剑桥大学教育学院苏珊·罗伯森教授,以对话的方式共同探讨交叉学科研究发展的机遇与陷阱。
