DirectionalVectorToDifferentiableScalarFunction
Creates a truly differentiable scalar function from a differentiable Vector
function, instead of using a forward-differences approximation to the
derivative like DirectionalVectorToScalarFunction does.
|
class |
DirectionalVectorToScalarFunction
Maps a vector function onto a scalar one by using a
directional vector and vector offset, and the parameter to the
function is a scalar value along the direction from the start-point
offset.
|
class |
LineMinimizerDerivativeBased.InternalFunction
Internal function used to map/remap/unmap the search direction.

AtanFunction
Returns the element-wise arctangent of the input vector, compressed between
-maxMagnitude and maxMagnitude (instead of just -PI/2 and PI/2)
|
class |
CosineFunction
A closed-form cosine function.
|
class |
HardSigmoidFunction
A hard sigmoid function, which is an approximation of a logistic sigmoid
whose output is between 0 and 1.
|
class |
HardTanHFunction
A hard sigmoid function, which is an approximation of a tanh sigmoid
whose output is between -1 and 1.
|
class |
IdentityScalarFunction
A univariate scalar identity function: f(x) = x.
|
class |
LeakyRectifiedLinearFunction
A leaky rectified linear unit.
|
class |
LinearFunction
