gasper 1.1.2.9000
gasper 1.1.2 relase
(01/06/2023)
- satisfy CRAN policy: ‘Packages which use Internet resources should
fail gracefully with an informative message if the resource is not
available or has changed (and not give a check warning nor error).’
- CRAN resubmission.
gasper 1.1.1 release
(02/16/2021)
- correction of an error in
laplacian_mat function (in
the case of full matrix input).
- replace
graphname by matrixname (matrices
in the SuiteSparse are not necessarily adjacency matrices).
- error correction in
SNR fun (wrong output for
matrices)
- add Peak Signal to Noise Ratio (
PNSR) function.
gasper 1.1.0 release
(02/09/2021)
- fix bug in
download_graph function for downloading
graph matrix without coordinates.
- add citation info issue#1.
- bibliography of SURE paper updated in the vignettes.
- add boolean argument allowing to export the coefficients of the
frame after thresholding (TRUE by default) in
SURE*thresh
functions (FALSE save memory allocation for large graphs).
- add a new output
dim to download_graph
providing a url to a temporary file containing the information about the
considered matrix.
- add new argument to
randsignal to avoid full spectrum
calculation.
- add new import (methods, Matrix, RSpectra) to consider large sparse
matrices.
- modify
randsignal to benefit from sparse computation
(much faster).
- add
SNR function (to remove rwavelet import used only
in vignettes)
- add a new output
dim to download_graph
providing the numbers of rows, columns and numerically nonzero elements
of the sparse matrix.
- add Matrix Market files import (remove data.frame storage to save a
lot of memory and speed-up computation) to
download_graph.
- add fast forward/inverse sgwt functions (
foward_sgwt
and inverse_sgwt). Faster than calculation via
tight_frame/analysis and potentially useful
when frame elements do not need to be calculated.
- add graph extension of the Von Neummann variance estimator using
finest scale coefficients (
HPFVN).
- add kernel tight-frame evaluation function
zetav (to
avoid redundancy).
- add new
plot_filter function (plot wavelet tight-frame
functions).
gasper 1.0.1 release
(07/27/2020)
- fix warnings bug
SUREthresh functions.
- adapt DESCRIPTION to meet CRAN’s expectations (i.e., omit the
redundant “in R” from the title, use the Authors@R field and declare
Maintainer, Authors and Contributors with their appropriate roles with
person() calls, do not start the description with “This package”,
package name, title or similar. Just start with “Provides …” or similar,
do not start the description with “This package”, package name, title or
similar).
- optionally specify a RNG seed (for reproducible experiments) in
swissroll.R.
- remove
adjacency_mat N arg.
- CRAN resubmission.
gasper 1.0.0 release
(07/23/2020)
- First release.
- CRAN submission.
