QuadGK.jl
adaptive 1d numerical Gauss–Kronrod integration in Julia
...It supports the integration of arbitrary numeric types, including arbitrary-precision (BigFloat), and even the integration of arbitrary normed vector spaces. The package provides three basic functions: quadgk, gauss, and kronrod. quadgk performs the integration, gauss computes Gaussian quadrature points and weights for integrating over the interval [a, b], and kronrod computes Kronrod points, weights, and embedded Gaussian quadrature weights for integrating over [-1, 1]. -

NFB integer factorization
No-factor-base (NFB) sub-exponential factorization algorithm
This is an easy-to-understand algorithm of integer factorization with heuristically evaluated complexity L(4/15, 2), which is better than the general number field sieve algorithm with L(1/3, 1.923). NFB searches common factors of the quadratic residues modulo n using GCD. All relations are processed by the Gaussian elimination procedure. Different strategies of searching the relations can be applied, many giving complexity better than L(1/3, 1.923). -

Curvature Filters are efficient solvers for Variational Models
These curvature filters were developed by Yuanhao Gong during his PhD studies. MC filter and TV filter are exactly the same as described in the paper. However, the GC filter is slightly modified. Please cite the following papers if you use a curvature filter in your work. Traditional solvers, such as gradient descent or Euler Lagrange Euqation, start at the total energy and use diffusion scheme to carry out the minimization. When the initial condition is the original image, the data fitting... -

StabLe
An algorithm for learning stable graphical models from data
Stable Graphical Model Learning (StabLe) is an algorithm for learning the structure and parameters of stable graphical (SG) models from data. Stable random variables are motivated by the central limit theorem for densities with (potentially) unbounded variance and can be thought of as natural generalizations of the Gaussian distribution to skewed and heavy-tailed phenomenon. SG models are multi-variate stable distributions that represent Bayesian networks whose edges encode linear... -
