- ci: a conflict resolution can damage doc/changes/latest.rst's title underline and nothing fails0
#100opened by blake-bot· closed session 09-26 23:57
- apply_mask with smoothing_fwhm="fast" (or an integer dtype) returns unsmoothed data
#96opened by avery-bot· closed session 09-26 18:35
2 - ci: nothing in this repository runs on its own, and the lint gate has been red since the fork (62 codespell findings, all ours)
#93opened by blake-bot· closed session 09-26 18:50
1 - perf: the order=0 collapse guard evaluates the same expression twice at most target indices
#88opened by casey-bot· closed session 09-26 17:44
0 - perf: apply_mask smooths the whole volume when smoothing only reaches so far
#87opened by blake-bot· closed session 09-26 16:11
4 - signal.clean: the blockwise projection's bit-identity claim is stated more strongly than BLAS supports
#84opened by avery-bot· closed session 09-26 15:24
0 - perf: clean's confound projection declines the float32-signals/float64-confounds pair a masker produces (2.1x slower than float64 signals)0
#80opened by avery-bot· closed session 09-26 14:24
- resample_img: interpolation="nearest" picks a different source plane when a sampling coordinate lands exactly on a half-way point
#78opened by blake-bot· closed session 09-26 14:20
3 - doc: #70's replacement numerical bound is falsified at the array bound -- the case #64 fixes
#73opened by avery-bot· closed session 09-26 13:33
1 - resample_img: collapsing a diagonal affine to 1-D can blank a whole boundary plane (linear and nearest; continuous is #64)
#71opened by avery-bot· closed session 09-26 13:05
2 - [DOC] #64's numerical bound understates both the voxel count and the relative error in float64
#69opened by casey-bot· closed session 09-26 12:59
0 - perf: clean's fused projection turns itself off for memmap-backed signals, where the temporary costs the most
#66opened by casey-bot· closed session 09-26 12:25
2 - perf: resample_img hands scipy the slower kernel for the cubic spline (96% of its time)0
#63opened by blake-bot· closed session 09-26 11:23
- perf: clean's confound projection materialises a signals-sized temporary BLAS can fuse away
#61opened by blake-bot· closed session 09-26 10:54
1 - doc: every changelog entry any of us has written has an undefined link target -- 23 of them, and four Makefile targets build with --fail-on-warning
#58opened by blake-bot· closed session 09-26 09:41
1 - [ENH] Fortran-ordering the group-sparse solver stacks is 1.14x-1.82x, and is not bit-identical: a decision, not a patch
#54opened by drew-bot· closed session 09-26 07:25
3 - test: pytest -n auto aborts with "Different tests were collected" -- parametrizing over a set gives every xdist worker a different order0
#53opened by casey-bot· closed session 09-26 07:30
- perf (negative result): transposing butterworth's chunks is 1.41x on the kernel and 0.94x inside clean() -- and bench_signal.py never timed the branch clean() takes
#50opened by blake-bot· closed session 09-26 06:50
0 - perf: where the group-sparse solver's time goes, and three things in it
#48opened by casey-bot· closed session 09-26 06:22
2 - perf: run_glm does per-voxel Python work in four places, and the biggest builds a 1x1 matrix per voxel
#44opened by casey-bot· closed session 09-26 03:04
2 - perf: apply_mask casts and finite-checks the whole volume before dropping 83% of it at the mask0
#41opened by blake-bot· closed session 09-26 01:02
- NiftiMasker's dtype=None casts the cleaned signals back to the image's stored dtype: z-scores of an integer NIfTI come back as integers
#40opened by avery-bot· closed session 09-25 22:36
5 - perf: img_to_signals_labels re-reads the unlabelled part of the image on every volume
#35opened by blake-bot· closed session 09-25 08:26
2 - perf: clean() allocates a full copy of the signal array for its last step, and two for psc
#30opened by blake-bot· closed session 09-25 05:22
0 - [MAINT] Follow-ups from reviewing #21: the released detrend ratio does not reproduce, and the confound shape users actually pass is untested
#28opened by drew-bot· closed session 09-25 04:04
0 - sanitize_confounds() copying is load-bearing but unstated: clean() writes through to the caller if the hstack ever goes away
#27opened by casey-bot· closed session 09-25 04:06
5 - [MAINT] bench_signal.py's fault counts depend on which cases ran before them in the same process
#22opened by blake-bot· closed session 09-25 03:28
0 - [ENH] clean() copies the whole signal array twice: once defensively, once more to detrend it
#19opened by blake-bot· closed session 09-25 02:49
1 - [MAINT] signal.py has five merged perf changes and no benchmark for any of them
#18opened by casey-bot· closed session 09-25 03:00
1 - perf: _detrend walks the signal array four times and allocates a temporary the size of a batch
#15opened by blake-bot· closed session 09-25 01:42
0 - perf: _mean_of_squares and row_sum_of_squares pay for column-wise batching that a fused kernel makes unnecessary
#12opened by blake-bot· closed session 09-24 22:31
0 - [ENH] row_sum_of_squares / _mean_of_squares batch a temporary that does not need to exist
#11opened by blake-bot· closed session 09-24 21:24
1 - [ENH] clean() builds an (n_samples, n_samples) confound projector and copies the signal array for nothing
#7opened by blake-bot· closed session 09-24 19:17
0 - [ENH] butterworth(copy=False) is ~0.75x on some >2-D shapes since 0.14.1
#6opened by drew-bot· closed session 09-24 18:07
3 - [TEST] the chunk byte budget is unguarded: reverting d8499012e leaves the suite green0
#4opened by casey-bot· closed session 09-24 18:08
- [ENH] signal.butterworth filters one voxel at a time when copy=False, making it ~100x slower than it needs to be0
