codeSource code Multivariate Gaussian Inference of Protein Contacts from Multiple Sequence Alignment
This archive file provides the MATLAB functions which read a multiple sequence alignment (in FASTA format) and return a direct-information (DI) matrix between all pairs of positions in the aligned amino-acid sequences, using a multivariate Gaussian model. RBP algorithm for lossy compression in reduced, ultrasparse GF(q) codes
This code implements a novel data compression technique for binary symmetric sources based on the cavity method over GF(q), the Galois Field of order q. We present a scheme of low complexity and near-optimal empirical performance. The compression step is based on a reduction of a sparse low-density parity-check code over GF(q) and is done through the so-called reinforced belief-propagation equations. These reduced codes appear to have a nontrivial geometrical modification of the space of codewords, which makes such compression computationally feasible.
Prize-Collecting Steiner Trees
This is the distribution package of MSGSTEINER The permission to use this software is granted by the authors, Alfredo BP for the diluted perceptron
This is code for biological data analysis using a multi-state diluted discrete perceptron. SBPI for binary perceptron learning
SBPI is an algorithm implementing the extremely simple learning protocol for networks with binary synapses reported in Efficient supervised learning in networks with binary synapses. The version named SBPI-MPI is a parallelized version which can be run on a cluster, using the MPI parallelization library.
BP for binary perceptron learning
This is the code associated with Learning by message-passing in networks of discrete synapses
Survey Propagation
This is the Survey Propagation C source code, plus some old revisions. Survey Propagation is a generalization of Belief Propagation that is able to solve huge random SAT formulae close to the SAT/UNSAT threshold.
