In CAST: 'caret' Applications for Spatial-Temporal Models

CAST 0.8.1

• bugfix:
• failed checks on Fedora 34 fixed

CAST 0.8.0

• new features:
• knndm as an alternative to nndm for large training data
• modifications:
• transition from raster to terra

CAST 0.7.1

• new features:
• Mahalanobis distance for AOA assessment as option
• modifications:
• faster estimation of the AOA
• parallel option for AOA deprecated (see vignette)
  • delineation of the default threshold fixed as suggested in github.com/HannaMeyer/CAST/issues/46
• bugfix:
• fixed issue github.com/ropensci/rnaturalearth/issues/69

CAST 0.7.0

• new feature:
• nndm cross-validation as suggested by Milà et al. (2022)
• modifications
• plot_geodist works with NNDM
• trainDI works with NNDM
• rename of parameter folds in AOA and trainDI

CAST 0.6.0

• new feature:
• trainDI allows to calculate the DI of the training dataset separately from the aoa function
• plot and print functions for the AOA
• function to plot nearest neighbor distance distributions in geographic and feature space
• function global_validation added
• modifications
• extensive restructuring of the AOA function
• ffs and bss can be used with global_validation
• bugfix:
• error in manual assignment of weights fixed

CAST 0.5.1

• resolved dependence on package "GSIF" which was removed from the CRAN repository

CAST 0.5.0

• new feature:
• AOA can run in parallel
• calibration of the DI (calibrate_aoa)
• bugfix:
• aoa will work now with large training sets
• modifications:
• default threshold of AOA changed

CAST 0.4.2

• new feature:
• aoa now working with categorical variables
• bugfix:
• fixed error in ffs when >170 variables are used
• minor changes:
• changed order of parameters in aoa
• tutorial "Introduction to CAST" improved

CAST 0.4.1

• new feature:
• vignette: tutorial introducing the "area of applicability"
• variable threshold for aoa
• various modifications in aoa in line with submitted paper

CAST 0.4.0

• new feature:
  • new function "aoa": quantify and visualize the area of applicability of spatial prediction models
  • "minVar" in ffs: Instead of always starting with 2-pair combinations, ffs can now also be started with combinations of more variables (e.g starting with all combinations of 3)
• bugfix:
• ffs failed for "svmLinear" in previous version because of S4 class issues. Fixed now.

CAST 0.3.1

• bugfix:
• CreateSpaceTimeFolds accepts tibbles
• CreateSpaceTimeFolds automatically reduces k if necessary
• ffs accepts further arguments taken by caret::train
• new feature: plot_ffs has option to plot selected variables only

CAST 0.3.0

• new feature: Best subset selection (bss) with target-oriented validation as (very slow but very reliable) alternative to ffs

• minor adaptations: verbose option included, improved examples for ffs

• bugfix: minor adaptations done for usage with plsr

CAST 0.2.1

• new feature: Introduction to CAST is included as a vignette.

• bugfix: minor error fixed in using user defined metrics for model selection.

CAST 0.2.0

• bugfix: ffs with option withinSE=TRUE did not choose a model as "best model" if it was within the SE of a model that was trained in an earlier run but had the same number of variables. This bug is fixed and if withinSE=TRUE ffs now only compares the performance to models that use less variables (e.g. if a model using 5 variables is better than a model using 4 variables but still in the SE of the 4-variable model, then the 4-variable model is rated as the better model).

• new feature: plot_ffs plots the results of ffs to visualize how the performance changes according to model run and the number of variables being used.

CAST 0.1.0
