Methods
public static float linearSaturated (float $floatValue) [171]
  • return: (-1 .. 1)
  • access: public
  • float $floatValue
public static float linearSaturated01 (float $floatValue) [189]
  • float $floatValue
public static integer random (integer $floatValueMin, [integer $floatValueMax = 10]) [140]
  • integer $floatValueMin: (Default: 0)
  • integer $floatValueMax: (Default: 10)
public static float sigmoid (float $floatValue) [63]
  • float $floatValue
public static float sigmoidI (float $floatValue) [77]

First derivative of sigmoid()

  • return: (between near 0 and near 1)
  • access: public
  • float $floatValue
public static integer sign (float $floatValue) [156]

Return the sign of a number

If $floatValue is positive the method returns 1 otherwise -1.
