Approximating the Plenoptic Function

The full plenoptic function describes all of the light passing through some volume of space. This information has at least seven dimensions: a ray of light requires five numbers to locate it (a point in space and a direction), plus wavelength and time. Given a digital representation of the plenoptic function, we can reconstruct arbitrary views of a scene. Unfortunately, adequately sampling the ...

Approximating the erfinv function

The inverse error function erfinv is a standard component of mathematical libraries, and particularly useful in statistical applications for converting uniform random numbers into Normal random numbers. This chapter presents a new approximation of the erfinv function which is significantly more efficient for GPU execution due to the greatly reduced warp divergence.

Galaxy Luminosity Function: A New Analytic Expression

We propose a new analytic approximation for the luminosity function of galaxies. The suggested expression behaves like the Schechter function at the faint end (φ ∼ L) but departs considerably at the bright end (L >> L∗). We argue here that such a behavior may provide a better fit for the current observational data than does the Schechter function. Its practical interest is stressed by consideri...

Optimal information for approximating periodic analytic functions

Let Sβ := {z ∈ C : | Im z| < β} be a strip in the complex plane. For fixed integer r ≥ 0 let Hr ∞,β denote the class of 2π-periodic functions f , which are analytic in Sβ and satisfy |f(r)(z)| ≤ 1 in Sβ . Denote by Hr,R ∞,β the subset of functions from Hr ∞,β that are real-valued on the real axis. Given a function f ∈ Hr ∞,β , we try to recover f(ζ) at a fixed point ζ ∈ R by an algorithm A on t...

Approximating the Bethe Partition Function

When belief propagation (BP) converges, it does so to a stationary point of the Bethe free energy F , and is often strikingly accurate. However, it may converge only to a local optimum or may not converge at all. An algorithm was recently introduced by Weller and Jebara for attractive binary pairwise MRFs which is guaranteed to return an !-approximation to the global minimum of F in polynomial ...
