Class Summary
Class	Description
Abs
Add
Atanh
BiLaplacian	Sparsified Laplacian, v1 Log prior for an laplacian distribution with an extra mass at zero, eg a mixture of a laplacian with another much narrower laplacian.
BiLaplacianBlend	Log prior for an laplacian distribution with an extra mass at zero, eg a mixture of a laplacian with another much narrower laplacian.
CauchyInfomax	cauchy distribution score function
CompoundFunction
Exp
ExponentialSquashing	Zero for t<0, linear near 0, exponentially tending to 1
Gamma	Implementation of the real (incomplete) Gamma function.
HalfSquare
Hamming
Hanning
HybridFunction	Piecewise function made of two other functions, f and g.
Log
LogAbs
LogCauchy
LogCosh	Actually 2 log cosh: - log prior of sech^2 disribution like abs but with rounded bottom Amount of rounding is adjustable
LogGenCosh	Actually NEGATIVE log cosh: like abs but with rounded bottom Amount of rounding is adjustable
LogGenExp	Generalised exponential log prior Blending to quadratic at zero
LogGenExp2	This version has a quadratic phase, a linear phase, and finally, a power law phase.
LogisiticInfomax
LogisticHyperplane
Negate
Power
Quadratic
RaleighLogPrior	Density is linear near zero, rising to a peak, decaying with a Gaussian tail.
Reciprocal
Scale
ScaledFunction
Sgn
SparseExponential	Single-sided (ie positive only) version of SparseLaplacian.
Sqrt
Square
Step
Tanh
ThresholdLog	Log with lower cut-off, then constant
WinnerTakeAll	This is NOT and element-wise nonlinearity, but rather a function of an entire vector.
