In sakuramomo1005/biADMM: Convex bicluster alogrithm based on ADMM algorithm

Description

bi-ADMM: a Biclustering Algorithm for the General Model

Usage

biADMM(
  X,
  nu1,
  nu2,
  gamma_1,
  gamma_2,
  m = 5,
  phi = 0.5,
  prox = "l2",
  niter = 1000,
  tol = 0.1,
  output = 1
)

Arguments

X	The data matrix to be clustered. The rows are the samples, and the columns are the features.
nu1	A regularization parameter for row shrinkage
nu2	A regularization parameter for column shrinkage
gamma_1	A regularization parameter for row shrinkage
gamma_2	A regularization parameter for column shrinkage
m	m-nearest-neighbors in the weight function
phi	The parameter phi in the weight function
prox	The proximal maps. Could calculate L1 norm, L2 norm, or L-infinity, use "l1", "l2", or "l-inf", respectively.
tol	Stopping criterion
output	When output = 1, print the results at each iteration. No print when output equals other value.
niters	Iteraion times

Value

A list of results, containing matrix of A, v, z, lambda1, and lambda2

Examples

# generate dataset
set.seed(123)
X = data_gen(n = 100, p = 80)
# set parameters
nu1 = nu2 = gamma_1 = gamma_2 = 0.1
m = 5
phi = 0.5
# biADMM algorithm
res1 = biADMM(X, nu1, nu2, gamma_1, gamma_2,
 m, phi, niter = 10, tol = 0.0001, output = 0)
dim(res1$A)
