polykde 1.0.0
polykde 1.1.3
- Add cross-validation bandwidths with exact loss for vMF
distributions in
bw_cv_polysph().
- Add
fast_log_c_vMF() as a faster version of
rotasym::c_vMF().
- Add exact MISE for vMF distributions.
- Fix error in r-devel-linux-x86_64-fedora-clang reported on
2025-04-15.
polykde 1.1.4
- Add hippocampus dataset to give replicability to García-Portugués
and Meilán-Vila (2024) (doi:10.48550/arXiv.2411.04166).
polykde 1.1.7
- Add
d_mvmf_polysph() and r_mvmf_polysph()
to handle mixtures of vMF distributions on polyspheres.
- Add exact ISE for vMF distributions.
- Expand support of
fast_log_c_vMF() to large
orders.
- Add Hammer projection convenience
hammer_to_sph() and
fib_latt().
- Update reference García-Portugués and Meilán-Vila (2025) to the
published version.
polykde 1.2.0
- Add
arcsinh to bw_cv_polysph() to handle
high-dimensional data.
- Move
Bessel from Suggests to
Imports.
- Fix the Monte Carlo LSCV loss in
bw_cv_polysph(exact_vmf = FALSE), which mixed densities
with respect to the Lebesgue and uniform measures.
- Extend and speed up the spline approximation of the Bessel functions
used by
fast_log_c_vMF(): the tabulated orders now reach
nu = 24.5, interpolation is done on log(x),
small arguments use an exact series, and non-tabulated orders fall back
to besselI() instead of erroring.
- Robustify the JSD test in
hom_test_polysph() against
non-finite values; use the standard permutation p-value
(1 + #{T* >= T}) / (B + 1).
- Fix the normalizing constants of the Epanechnikov and softplus
product kernels in
grad_hess_kde_polysph().
- Fix
proj_grad_kde_polysph() with
sparse = TRUE, which could request too few eigenvalues for
small r.
- Accept a length-
r vector kappa for
one-component mixtures in d_mvmf_polysph(),
r_mvmf_polysph(), and mise_vmf_polysph().
- Restore the user’s random seed on exit whenever
seed_mc, seed_psi, or seed_jsd
are given.
- Validate inputs in
log_cv_kde_polysph(),
bw_lcv_min_epa(), and proj_polysph().
- Add a package logo.
- And the reference García-Portugués and Meilán-Vila (2023)
(doi:10.1007/978-3-031-32729-2_4) to CITATION.
- Documentation improvements.
polykde 1.2.1
- Unrandomize the tests in
tests_bwd.R,
tests_distr.R, tests_grad_hess.R,
tests_kde.R, tests_samplers.R, and
tests_tests.R to avoid spurious failures on some
platforms.
