predict.gradDescentRObject: The gradDescentR prediction stage

In gradDescentR: Gradient Descent for Regression Tasks

Description

This is the main function to obtain a final result as predicted values for all methods in this package. In order to get predicted values, this function is run using an gradDescentRObject, which is typically generated using gradDescentR.learn.

Usage

## S3 method for class 'gradDescentRObject'
predict(object, newdata, ...)

Arguments

object	an gradDescentRObject.
newdata	a data frame or matrix (m \times n) of data for the prediction process, where m is the number of instances and n is the number of input variables. It should be noted that the testing data must be expressed in numbers (numerical data).
...	the other parameters (not used)

Value

The predicted values.
