The sigmoid function models phenomena at the single unit level, like refractoriness and spike rate adaptation and aspects of neuronal ensembles at the population level, like the distribution of thresholds involved in the generation of action potentials. From: Statistical Parametric Mapping, 2007. Related terms: WebThe sigmoid function is also called a squashing function as its domain is the set of all real numbers, and its range is (0, 1). Hence, if the input to the function is either a very large negative number or a very large positive number, the output is always between 0 and 1. Same goes for any number between -∞ and +∞. how to import 3d model in unity
