What kind of activation functions for Neural Networks are supported by ADAPA?

ADAPA supports all the PMML list of activation functions for the Neural Network model element.

In PMML, activations functions are divided into two groups. Group 1 contains the following functions:
  • threshold
  • logistic
  • tanh
  • identity
  • exponential
  • reciprocal
  • square
  • Gauss
  • sine
  • cosine
  • Elliott
  • arctan
Group 2 contains only one function:
  • radialBasis
For more details, please take a look, for example, at the PMML 4.0 Neural Network specification.
