R Documentation

Sampling Paired Observations

Description

A sampler used to samples the batches where each instances is sampled twice

Usage

paired_sampler(vaeac_dataset_object, shuffle = FALSE)

Arguments

`vaeac_dataset_object`	A `vaeac_dataset()` object containing the data.
`shuffle`	Boolean. If `TRUE`, then the data is shuffled. If `FALSE`, then the data is returned in chronological order.

Details

A sampler object that allows for paired sampling by always including each observation from the vaeac_dataset() twice. A torch::sampler() object can be used with torch::dataloader() when creating batches from a torch dataset torch::dataset(). See https://rdrr.io/cran/torch/src/R/utils-data-sampler.R for more information. This function does not use batch iterators, which might increase the speed.
