Math Functions

Handle sigmoid and hyperbolic operations

Apoc provides a set of function useful to ML purpose. All these functions returns a Double value.

Statement Description

apoc.math.sech(val)

returns the hyperbolic secant

apoc.math.sigmoid(val)

returns the sigmoid value

apoc.math.sigmoidPrime(val)

returns the sigmoid prime [ sigmoid(val) * (1 - sigmoid(val)) ]

apoc.math.sinh(val)

returns the hyperbolic sin

apoc.math.tanh(val)

returns the hyperbolic tangent

apoc.math.coth(val)

returns the hyperbolic cotangent

apoc.math.cosh(val)

returns the hyperbolic cosin

apoc.math.csch(val)

returns the hyperbolic cosecant
