Description Usage Format Methods See Also

Description

SVDMaster objects instantiate and run a distributed SVD computation

Usage

1

Format

An R6Class generator object

Methods

SVDMaster$new(defnId, k, debug=FALSE)

Create an SVD master object with the specified id, the number of singular vectors desired, and the debugging flag. The debug flag is used for debugging computations

kosher()

Check if inputs and state of object are sane. For future use

updateV(arg)

Return an updated value for the V vector

updateU(arg)

Return an updated value for the U vector

fixFit(v, d)

Construct the residual matrix using given the v vector and d so far

reset()

Initialize the computation

dimX(, ...)

Return the dimensions of the matrix

normU(arg, ...)

Normalize U vector by arg

addSite(name, url)

Add a worker site for participating in the distributed computation

run(k = private$k, thr = 1e-8, max.iter = 100)

Run the SVD computation until either the threshold is reached or the max.iter number of iterations are used up

summary()

Return the summary of results
