Mhorseshoe package in R: Approximate algorithm for the horseshoe prior in Bayesian linear model

SoftwareX
The horseshoe prior is a continuous shrinkage prior frequently used in high-dimensional Bayesian sparse linear regression models. Although the horseshoe prior theoretically guarantees excellent shrinkage properties, performing a Markov Chain Monte Carlo (

A hybrid decoding of Reed–Muller codes

International Journal of Distributed Sensor Networks, 2017
In this article, a hybrid decoding algorithm for Reed–Muller codes is presented. Unlike the conventional algorithm, the presented algorithm ends recursive decomposition when R ( 1 , m ) and R ( m − 1 , m ) appeared.

DS-theory. Research of R-data division factors in order to generate applied algorithms. Part 2

, 2017
This is the next essay from the cycle describing the theory of decomposition schemes as the theory of applied algorithms. A decomposition scheme is being considered as a prototype of an applied algorithm.

topicmodels: An R Package for Fitting Topic Models [PDF]

, 2011
Topic models allow the probabilistic modeling of term frequency occurrences in documents. The fitted model can be used to estimate the similarity between documents as well as between a set of specified keywords using an additional layer of latent ...

Algorithm Shootout: R versus RHMC

, 2005
We present initial results comparing the RHMC and R algorithms on large lattices with small quark masses using chiral fermions. We also present results concerning staggered fermions near the deconfinement/chiral phase transition.

Detection of Straw Coverage under Conservation Tillage Based on an Improved Mask Regional Convolutional Neural Network (Mask R-CNN)

Agronomy
Conservation tillage, a crucial method for protecting soil fertility, depends heavily on maintaining adequate straw coverage. The current method of straw coverage detection relies primarily on manual measurement, which is both time-consuming and ...

Neighbourhood Constraint for a Tabu Search

, 2001
this paper we have introduced a new neighbourhood structure for the R Cmax problem. Although our algorithm is based in reassign and swap neighbourhood already used by other heuristics for this problem the approach is innovative.

Approximating the smallest $k$-enclosing geodesic disc in a simple polygon

Journal of Computational Geometry
We consider the problem of finding a geodesic disc of smallest radius containing at least $k$ points from a set of $n$ points in a simple polygon that has $m$ vertices, $r$ of which are reflex vertices. We refer to such a disc as a SKEG disc. We present
