激活函数(Activation functions)对于人工神经网络模型去学习、理解非常复杂和非线性的函数来说具有十分重要的作用。它们将非线性特性引入到我们的网络中。如图1,在神经元中,输入的 inputs 通过加权,求和后,还被作用了一个函数,这个函数就是激活函数。引入激活函数是为了增加神经网络模型的非线性。没有激活函数的每层都...
2023,Computers and Electronics in Agriculture YingChen, ...WanqiangQian 2.1.2Activation function The main function of theactivation functionis to provide the nonlinear modelling ability of the network. Commonly used activation functions are sigmoid, softmax, tanh, and swish.Jiang et al. (2021)and...

1a,b). We profiled cells in resting state, before dividing (16 h), after the first cell division (40 h) and after acquiring effector functions (5 d)19. This process resulted in high-quality data for 655,349 cells (Methods and Supplementary Fig. 1c–g). Fig. 1: A single-cell...
Nevertheless, our understanding of AMPK’s specific regulation and involvement in neural functions such as anxiety remains limited. Our study, utilizing repeated social defeat (RSD) mouse models and transgenic mouse models [27, 28], revealed that diminished AMPK activity in the medial prefrontal ...

Furthermore, Gene Ontology (GO) and Kyoto Encyclopedia of Gene and Genomes (KEGG) analyses were conducted to assess potential functions of the differentially expressed genes (DEGs). The results of WGCNA combined with the results of function enrichment analysis of DEGs were used as a basis for ...
The induction of hepatic FGF21 expression by diverse types of hepatic stress indicates that FGF21 is a stress-responsive hepatokine that is activated during liver pathogenesis and injury that impinge on its normal metabolic functions in behalf of the organism. Induced FGF21 in turn acts as a sec...
In literature we usually find the expression “trainable activation functions”, however the expressions “learneable”, “adaptive” or “adaptable” activation functions are also used, see, for example, Apicella et al., 2019, Qian et al., 2018 and Scardapane, Van Vaerenbergh, Totaro, and...
To date, few studies have focused on GSDME functions in the central nervous system; however, our study highlights the importance of GSDME-mediated signaling in the process of neuroinflammation and neurodegeneration. Indeed, we also detected gasdermin activation in CAPON-overexpressing mice, which show ...
