Modified hyperbolic tangent : ウィキペディア英語版 | Modified hyperbolic tangent The modified hyperbolic tangent (mtanh or mth) is a special S-shaped function based on the hyperbolic tangent, given by : This function was proposed by Elena Soboleva (of Ukraine) as a utility function for multi-objective optimization and choice modelling in decision-making. In other papers it is used for approximation of current-voltage characteristics of field-effect transistors and light-emitting diodes. With parameters ''a'' = ''b'' = ''c'' = ''d'' = ''1'' the modified hyperbolic tangent function reduces to the conventional tanh(''x'') function, whereas for ''a'' = ''b'' = ''1'' and ''c'' = ''d'' = ''0'', the term becomes equal to sinh(''x''). ==See also==
