KernelICA 2.0.0
Package reinstatement
- This release reinstates KernelICA on CRAN after the
package was previously archived.
- The issues that led to the archival have been resolved, and the
package has been updated to comply with current CRAN policies and
checks.
- Package maintenance has been transferred to a new maintainer.
- Updated package metadata to reflect the current authorship and
maintainer information.
Bug fixes
- Fixed an argument-order bug in the Hermite kernel implementation
affecting
kernel_matrix(..., kernel = "hermite") and
incomplete_cholesky(..., kernel = "hermite").
- Fixed validation of user-supplied initialization matrices in
kernel_ica().
- Fixed selection of the best solution across multiple random starts
in
kernel_ica().
- Improved handling of empty vectors and zero-length loops in several
functions by replacing
1:n and 1:length(x)
with seq_len() and seq_along().
- Added a guard in
MD_distant_matrices() for cases where
no additional matrices need to be generated.
incomplete_cholesky() now accepts integer input
consistently by coercing input to numeric.kernel_matrix() now validates the kernel
argument using match.arg().- Corrected the sign in the exponent of the Gaussian kernel.
Build system
- Modernized the C++ implementation by replacing manual memory
management with
std::unique_ptr.
- Added missing standard library includes required by current
compilers.
- Added
-DNDEBUG to release compilation flags.
- Explicitly specified the package name when loading Rcpp
modules.
Documentation
- Updated package documentation to derive author and maintainer
information directly from
DESCRIPTION.
- Removed redundant author annotations from individual help
pages.
- Corrected the citation year for the kernel ICA reference.
- Fixed several typographical errors in the documentation.
