Activation functions for both hidden and output neurons are logistic sigmoidal functions. The range of target values is scaled to [0.1 0.9] to prevent saturation during training process. The Levenberg–Marquardt numerical optimization technique is used as the back–propagation learning algorithm to ...
To our knowledge, the existence of a sigmoidal taste concentration-response function has yet to be investigated in a parametric manner within individuals. However, Bartoshuk (1975) has proposed that all three phases (compressive, linear, expansive) exist for taste stimuli, although not for one ...
Data were fitted to a three-parameter sigmoidal curve to derive IC50 values. Ki of the compounds were calculated using a tool provided by S. Wang’s laboratory (http://www.umich.edu/~shaomengwanglab/software/calc_ki/index.html). Data were plotted in GraphPad Prism 9.0. Cell culture MCF7...

The reservoir state s(t) and output o(t) at discrete time step t are described by [56]:s(t)=f(Wus·u(t)+Wss·s(t-1)+Wos·oT(t-1))o(t)=sT(t)·Wsowhere f is the reservoir activation function (typically a hyperbolic tangent or another sigmoidal function). u(t),s(t) and ...
Since Ftz is autoactivating, we expect the gene regulatory function to be S-shaped (i.e., sigmoidal), with no transcription in the absence of Ftz protein, a steep increase in transcription as Ftz levels approach a “threshold” level, and maximal transcription for high concentrations of Ftz....
In the primary screening of the 435 substances, their activation concentrations were analyzed using sigmoidal regression analysis with Prism 8 (GraphPad Software Inc.). For the selected chemicals and their mixtures, more detailed DRC analyses were conducted using R software (Ver. 4.3.1) (R [85]...
