tSNE: tSNE

In structToolbox: Data processing & analysis tools for Metabolomics and other omics

Description

t-Distributed Stochastic Neighbor Embedding.

Usage

tSNE(
  dims = 2,
  perplexity = 30,
  max_iter = 100,
  theta = 0.5,
  check_duplicates = FALSE,
  init = NULL,
  eta = 200,
  ...
)

Arguments

dims	(numeric) The number of tSNE dimensions computed. The default is 2.
perplexity	(numeric) Perplexity parameter. The default is 30.
max_iter	(numeric) The maximum number of tSNE iterations. The default is 100.
theta	(numeric) Speed/accuracy trade-off. A value of 0 gives an exact tSNE. The default is 0.5.
check_duplicates	(logical) Check for duplicates. Allowed values are limited to the following: "TRUE": Checks for the presence of exact duplicate samples. "FALSE": Does not check for exact duplicate samples. The default is FALSE.
init	(NULL, data.frame, DatasetExperiment) A set of coordinates for initialising the tSNE algorithm. NULL uses random initialisation. The default is NULL.
eta	(numeric) The learning rate parameter. The default is 200.
...	Additional slots and values passed to struct_class.
