plot.sgd {sgd}

Plot objects of class sgd.

Description

Plot objects of class sgd.

Usage

## S3 method for class 'sgd'
plot(x, ..., type = "mse", xaxis = "iteration")

## S3 method for class 'list'
plot(x, ..., type = "mse", xaxis = "iteration")

Arguments

x

object of class sgd.

...

additional arguments used for each type of plot. See ‘Details’.

type

character specifying the type of plot: "mse", "clf", "mse-param". See ‘Details’. Default is "mse".

xaxis

character specifying the x-axis of plot: "iteration" plots the y values over the log-iteration of the algorithm; "runtime" plots the y values over the time in seconds to reach them. Default is "iteration".
