- 1D infinite Gaussian mixture model
- License: Shareware
- Price:


This is a little script which was designed for educational purposes. It runs out of the box and generates a random data set of 1D Gaussian mixtures and visualizes the inference process.

- CT reconstruction package
- License: Shareware
- Price:


Set of functions performing ct reconstruction tasks like a radon transformation, a simple backprojection, a filtered backprojection using a convolution in the spatial domain, a filtered backprojection using a 2D Fourier transformation, and a filtered back projection using the central slice theorem. It includes the function myCtRecontruction that should run out of the box and uses Matlab's Shepp Logan Phantom for demonstration. It is also possible to run the myCtReconstruction with an argument myCtRecontruction(anyCtDataSet) to perform image reconstruction on a custom data set.

This archive includes a set of functions introducing into optimization and line search techniques. It was designed for educational purposes. Most of the functions run as script on toy problems. It is possible to visualize the line search and experiment with different update rules for the inverse Hessian in order to understand the optimization process. This package includes * conjugate gradient * BFGS algorithm * LBFGS algorithm * Levenberg Marquart algorithm * backtraicking Armijo line search * line search enforcing strong Wolfe conditions * line search bases on a 1D quadratic approximation of the objective function * a function for naive numerical differentation Have fun!
