kerntools 1.2.0
CRAN release: 2025-02-19
Major changes
- Two new kernels, ‘Aitchison()’ and ‘cLinear()’, for compositional data.
- A new kernel, ‘Chi2()’, for computing the chi-squared kernel for bags-of-words.
- New function, ‘aggregate_imp()’, that aggregates a table of features following a user-defined grouping criterion.
Minor improvements and bug fixes
- ‘plotImp()’ now throws an error when the user requests more features than the actual number of features present in x. Also, problems when displaying the correct xlim are fixed.
- ‘heatK()’ allows the user to input a legend title.
- ‘KTA()’ now only accepts binary variables for its parameter ‘y’.
