solve.XGBoost: Run the XGBoost Solver

In PriceLab/trena: Fit transcriptional regulatory networks using gene expression, priors, machine learning

Run the XGBoost Solver

Description

Given a TReNA object with XGBoost as the solver, use the cor function with method = "XGBoost" to esimate importances for each transcription factor as a predictor of the target gene's expression level.

Usage

## S4 method for signature 'XGBoostSolver'
run(obj)

Arguments

obj	An object of class XGBoostSolver

Value

The set of XGBoost relative importances between each transcription factor and the target gene.

Examples

# Load included Alzheimer's data, create a TReNA object with Bayes Spike as solver, and solve
load(system.file(package="trena", "extdata/ampAD.154genes.mef2cTFs.278samples.RData"))
target.gene <- "MEF2C"
tfs <- setdiff(rownames(mtx.sub), target.gene)
XGBoost.solver <- XGBoostSolver(mtx.sub, target.gene, tfs)
tbl <- run(XGBoost.solver)
