mlr3spatiotempcv: Spatiotemporal Resampling Methods for 'mlr3'

Spatiotemporal Blocking Methods

These methods use square/rectangular blocks for partitioning.

mlr_resamplings_spcv_block ResamplingSpCVBlock
(blockCV) Spatial block resampling
mlr_resamplings_repeated_spcv_block ResamplingRepeatedSpCVBlock
(blockCV) Repeated spatial block resampling
mlr_resamplings_spcv_tiles ResamplingSpCVTiles
(sperrorest) Spatial "Tiles" resampling
mlr_resamplings_repeated_spcv_tiles ResamplingRepeatedSpCVTiles
(sperrorest) Repeated spatial "tiles" resampling

Spatiotemporal Buffering Methods

These methods support using buffering zones which eventually remove observations between train and test sets.

mlr_resamplings_spcv_buffer ResamplingSpCVBuffer
(blockCV) Spatial buffering resampling
mlr_resamplings_spcv_disc ResamplingSpCVDisc
(sperrorest) Spatial "disc" resampling
mlr_resamplings_repeated_spcv_disc ResamplingRepeatedSpCVDisc
(sperrorest) Repeated spatial "disc" resampling
mlr_resamplings_sptcv_cstf ResamplingSptCVCstf
(CAST) Spatiotemporal "Leave-location-and-time-out" resampling
mlr_resamplings_repeated_sptcv_cstf ResamplingRepeatedSptCVCstf
(CAST) Repeated spatiotemporal "leave-location-and-time-out" resampling

Spatiotemporal Clustering Methods

These methods make use of clustering methods (e.g. k-means) to create (equally-sized) partitions.

mlr_resamplings_spcv_coords ResamplingSpCVCoords
(sperrorest) Coordinate-based k-means clustering
mlr_resamplings_repeated_spcv_coords ResamplingRepeatedSpCVCoords
(sperrorest) Repeated coordinate-based k-means clustering
mlr_resamplings_spcv_disc ResamplingSpCVDisc
(sperrorest) Spatial "disc" resampling
mlr_resamplings_repeated_spcv_disc ResamplingRepeatedSpCVDisc
(sperrorest) Repeated spatial "disc" resampling
mlr_resamplings_sptcv_cluto ResamplingSptCVCluto
(skmeans) Spatiotemporal clustering resampling via CLUTO
mlr_resamplings_repeated_sptcv_cluto ResamplingRepeatedSptCVCluto
(skmeans) Repeated spatiotemporal clustering resampling via CLUTO

Feature Space Clustering Methods

These methods cluster in the feature space and not (necessarily) in space or time.

mlr_resamplings_spcv_env ResamplingSpCVEnv
(blockCV) "Environmental blocking" resampling
mlr_resamplings_repeated_spcv_env ResamplingRepeatedSpCVEnv
(blockCV) Repeated "environmental blocking" resampling

Group-level Partitioning Methods

These methods use (multiple) factor-variables / inherited grouping to create partitions.

mlr_resamplings_sptcv_cstf ResamplingSptCVCstf
(CAST) Spatiotemporal "Leave-location-and-time-out" resampling
mlr_resamplings_repeated_sptcv_cstf ResamplingRepeatedSptCVCstf
(CAST) Repeated spatiotemporal "leave-location-and-time-out" resampling
