#2866 assigned enhancement

Hyperbolic functions for symbolic regression

Reported by: bwerth Owned by: msemenki
Priority: medium Milestone: HeuristicLab 3.3.16
Component: Problems.DataAnalysis.Symbolic Version: branch
Keywords: Cc: gkronber@heuristiclab.com, maffenze@heuristiclab.com

Description

Since the integrals of some hyperbolic functions are already included but not the functions themselves, and the hyperbolic tangent / logistic function is a widely used symbol in regression, they should be made available for non-linear/symbolic-regression.

Please see the changes that were necessary for the integration of Abs(), AQ(), cube() and cuberoot() in ticket #2915 and add tanh() as a new symbol for symbolic regression.

I reviewed the changes in r16375.

Please, also add support for the new symbol to the NativeInterpreter, BatchedInterpreter, and TreeToAutoDiffTermConverter.
