update_data_cat: Add the new sample into labeled dataset from unlabeled...

In seqest: Sequential Method for Classification and Generalized Estimating Equations Problem

Description

update_data_cat selects the sample to the labeled dataset according to it's index

Usage

update_data_cat(ind, splitted, data, train, labeled_ids, unlabeled_ids)

Arguments

ind	A numeric value denotes the index of selected sample.
splitted	A list containing the datasets which we will use in the categorical case. Note that the element of the splitted is the collections of samples from Classes 0 and Classes k.
data	A matrix denotes all the data including the labeled samples and the unlabeled samples. Note that the first column of the dataset is the response variable, that's the labels and the rest is the explanatory variables.
train	A matrix for the labeled samples.
labeled_ids	A numeric vector for the unique identification of the labeled dataset
unlabeled_ids	A numeric vector for the unique identification of the unlabeled dataset

Details

update_data_cat chooses the sample based on the index from all the training dataset if the data has no ordinal relation. Specifically, we remove the index of the choosed sample from the unlabeled dataset and add the index to the labeled dataset. Then, combine the selected sample with the existing training data set.

Value

splitted	a list containing the datasets which we add a new sample into it
newY	the label of the choosed sample
train	the dataset used for training the model after adding the new sample
labeled_ids	the id of the labeled dataset after updating
unlabeled_ids	the id of the unlabeled dataset after updating
