From 7d7f0d5f1668e3d76b3b6719cbd0be29ef9ca54a Mon Sep 17 00:00:00 2001 From: Martin Storath Date: Wed, 6 May 2026 14:29:34 +0000 Subject: [PATCH 01/11] Add Rust core + Python bindings for PyPI release Implements the CSSD algorithm from Storath & Weinmann (JCGS 2023) in Rust with NumPy-friendly Python bindings via PyO3 / maturin. * crates/cssd-core: pure Rust algorithm crate (DP, FPVI/PELT, Reinsch reconstruction, optional locally-adaptive Jacobi preconditioning). * crates/cssd-py: thin PyO3 binding -> _cssd_core extension module. * python/cssd: NumPy-friendly Python wrapper (cssd, cssd_cv, PiecewisePoly). * tests_py + crates/cssd-core/tests: ~210 unit + integration tests; the MATLAB-fixture parity tests auto-skip when fixtures aren't present. * demos_py: 7 ported demos (synthetic, HeaviSine, vector-valued, geyser CV, CPU time, preconditioning comparison). * .github/workflows: CI on push/PR + maturin-action release-on-tag pipeline. * README: adds Python install + quickstart section. * Wheels are abi3-py39 -> one wheel per platform covers Python 3.9+.

charset=UTF-8 Content-Transfer-Encoding: 8bit Six worked examples that double as a v0.1.0 release verification and a first-time-user introduction: 1. Smooth-only regime (γ=∞ ≡ classical smoothing spline) at three p values. 2. Single-discontinuity recovery (γ=∞ blurs, γ=1.0 finds the jump). 3. Heteroscedastic noise + multiple discontinuities with delta weights. 4. FPVI vs PELT pruning agreement (rtol < 1e-10 on coefs). 5. Automatic (p, γ) selection via cssd_cv 5-fold cross-validation. Cells render inline in the committed .ipynb; viewable on GitHub without re-execution. Run-all completes in <10 s. Used to be a CSSD-side parallel to demos_py/'s existing fixture-based content; this notebook is API-driven, not fixture-driven. --- demos_py/release_smoke_test.ipynb | 397 ++++++++++++++++++++++++++++++ 1 file changed, 397 insertions(+) create mode 100644 demos_py/release_smoke_test.ipynb diff --git a/demos_py/release_smoke_test.ipynb b/demos_py/release_smoke_test.ipynb new file mode 100644 index 0000000..5ff28ab --- /dev/null +++ b/demos_py/release_smoke_test.ipynb @@ -0,0 +1,397 @@ +{ + "cells": [ + { + "cell_type": "markdown", + "id": "287d9c3c", + "metadata": {}, + "source": [ + "# `cssd` — release smoke test\n", + "\n", + "Exercises the CSSD (cubic smoothing splines for discontinuous signals) Python API on small synthetic inputs to verify a release is functional.

Each tagged change is named after its PORTING_NOTES entry; cross-reference there for the rationale. Bug fixes (output-affecting): B1 cssd.m: PELT/FPVI rolling-CV used stale stored_R/stored_z when no candidate improved F(rb). Fall back to first_lb's updated state (PELT) or extrapolate from x_{rb-1} (FPVI), so rcv_score is always a valid extrapolation residual. B3 cssd.m: rcv_score / (N-2) divided by zero for N <= 2; install_cssd's smoke test was hitting it. Score is now 0 in that regime; smoke test bumped from N=2 to N=3. B4 cssd_cv.m: inputParser was named 'p', shadowing the smoothing parameter; renamed to 'parser'. B5 cssd_cv.m: K=5 default applied only when both cv_type AND cv_arg were defaulted, so cssd_cv(x, y, 'random') crashed. Default now kicks in whenever cv_arg is empty. B6 cssd.m: invalid pruning string silently fell through to FPVI; the switch's 'otherwise' branch is now an explicit error and FPVI is its own case. B7 PcwFunReal.m: eval allocated NaN(size(xx)), correct only for scalar pieces. Reshaped to (numel(xx), dim) so vector-valued pp output (csaps with dim > 1) is handled. Plot helper updated to match. B8 cssd_cv.m: gamma_pq parametrisation gave NaN at the q=1 boundary (0 * Inf = NaN for p=0, q=1). Clamped q upper bound to 1-eps and max(1-q, eps) in the formula. Audit notes (preconditions / robustness): N1 chkxydelta.m: documented the implicit Curve Fitting Toolbox dependency on chckxywp. N2 linext_pp.m: forced pp.breaks to a row before concat to handle column-shaped breaks; clearer assertion message. N3 merge_ppcell.m: assert consecutive endpoints match (was silently dropping the previous-end break). N4 spline_innerenergy.m: documented dependence on natural BC. N5 cssd.m: assertion message updated to match the (non-strict) check on gamma. N6 kfoldcv_split.m: assert 2 <= K <= N. N8 cssd.m: gamma=Inf branch now uses linext + embed_pptocubic so output.pp has the same domain convention as the DP branch. tests/TestCSSD.m (+142 lines): regression tests for each B*/N* fix, named test__* for cross-reference with PORTING_NOTES.md. Output behaviour change: rcv_score values for the same (x, y, p, gamma) input differ between this commit and HEAD~1. Consumers of rcv_score (only diagnostic / hyperparameter selection) should regenerate any cached scores. pp.coefs, pp.breaks, discont, discont_idx are unaffected by these fixes. --- cssd.m | 108 ++++++++++++++++++----- cssd_cv.m | 40 ++++++--- install_cssd.m | 20 +++-- subroutines/PcwFunReal.m | 114 ++++++++++++++++++------- subroutines/chkxydelta.m | 9 ++ subroutines/kfoldcv_split.m | 7 ++ subroutines/linext_pp.m | 12 ++- subroutines/merge_ppcell.m | 18 ++-- subroutines/spline_innerenergy.m | 10 ++- tests/TestCSSD.m | 142 ++++++++++++++++++++++++++++++- 10 files changed, 400 insertions(+), 80 deletions(-) diff --git a/cssd.m b/cssd.m index b1a52c1..14a24e5 100644 --- a/cssd.m +++ b/cssd.m @@ -31,12 +31,26 @@ % % Output % output = cssd(...) -% output.pp: ppform of a smoothing spline with discontinuities; if xx is specified, -% the evaluation of the result at the points xx is returned +% output.pp: ppform of a smoothing spline with discontinuities.

The previous fixture-based test_matlab_parity.py loaded 594 pre-baked .mat files generated by matlab_fixtures/dump_fixtures.m. Those fixtures were generated against pre-audit MATLAB (HEAD~1) and are now stale for the rcv_score field (B1, B2 fixed) — though pp.coefs / pp.breaks / discont_idx remain valid. The live approach removes the fixture maintenance burden and surfaces regressions in either implementation immediately. Skipped (not failed) when the matlab shim is unavailable. Test cases (8 total, ~50s): - Step signal × FPVI / PELT, two (p, γ) settings: 4 cases - Smooth quadratic with γ=∞ (degenerates to classical smoothing spline): 1 case - Random Gaussian signals × 3 seeds × varied (n, p, γ): 3 cases Tolerances: atol=1e-8 / rtol=1e-5 on pp.coefs (LAPACK QR vs Givens QR divergence is the limiter); atol=1e-10 on pp.breaks; exact on discont_idx. Verified all 8 pass against the audit-fixed MATLAB at HEAD. The orphaned tests_py/fixtures/ directory (594 .mat files) and matlab_fixtures/dump_fixtures.m are left in place; cleanup is a separate decision. --- tests_py/test_matlab_parity.py | 274 ++++++++++++++++++++++----------- 1 file changed, 183 insertions(+), 91 deletions(-) diff --git a/tests_py/test_matlab_parity.py b/tests_py/test_matlab_parity.py index 7adf66d..642406e 100644 --- a/tests_py/test_matlab_parity.py +++ b/tests_py/test_matlab_parity.py @@ -1,109 +1,201 @@ -"""Parity tests against MATLAB-generated fixtures. - -Run ``matlab_fixtures/dump_fixtures.m`` from MATLAB first to populate -``tests_py/fixtures/``.

No test referenced it after the rewrite. Removed; conftest.py is now an empty scaffold (one-liner docstring). - .gitignore had two entries (`tests_py/fixtures/` and `matlab_fixtures/`) for now-deleted directories. Removed. - Local copies of tests_py/fixtures/ (594 .mat files, ~2.9 MB) and matlab_fixtures/dump_fixtures.m were untracked artifacts of the fixture-generation workflow and were rm -rf'd in the working tree. The 211 remaining Python unit tests still pass. --- .gitignore | 4 ---- tests_py/conftest.py | 14 -------------- 2 files changed, 18 deletions(-) diff --git a/.gitignore b/.gitignore index 22892c1..56cb541 100644 --- a/.gitignore +++ b/.gitignore @@ -20,13 +20,9 @@ python/cssd/_cssd_core* /target/ Cargo.lock.bak -# Test fixtures (generated locally from MATLAB by matlab_fixtures/dump_fixtures.m) -tests_py/fixtures/ - # Internal / historical docs not shipped to PyPI PORTING_NOTES.md PAPER_COMPLIANCE.md -matlab_fixtures/ # Devcontainer .devcontainer/ diff --git a/tests_py/conftest.py b/tests_py/conftest.py index 5f15df3..6df2cbc 100644 --- a/tests_py/conftest.py +++ b/tests_py/conftest.py @@ -1,15 +1 @@ """Shared pytest fixtures for the Python test suite.""" - -from __future__ import annotations - -from pathlib import Path - -import pytest - - -FIXTURES = Path(__file__).parent / "fixtures" - - -@pytest.fixture(scope="session") -def fixtures_dir() -> Path: - return FIXTURES From dd3cd1b545cf55bf3441c26c9a1fe6506998bd63 Mon Sep 17 00:00:00 2001 From: Martin Storath Date: Thu, 7 May 2026 20:01:52 +0000 Subject: [PATCH 10/11] Format matlab_parity.rs to satisfy CI rustfmt check --- crates/cssd-core/tests/matlab_parity.rs | 41 ++++++++++++++++++++----- 1 file changed, 33 insertions(+), 8 deletions(-) diff --git a/crates/cssd-core/tests/matlab_parity.rs b/crates/cssd-core/tests/matlab_parity.rs index dbba1b5..a23d6af 100644 --- a/crates/cssd-core/tests/matlab_parity.rs +++ b/crates/cssd-core/tests/matlab_parity.rs @@ -38,7 +38,10 @@ fn repo_root() -> PathBuf { fn workspace_root() -> PathBuf { // .../devcontainer/10-OwnRepos/CSSD -> .../devcontainer - repo_root().join("../..").canonicalize().expect("workspace root resolves") + repo_root() + .join("../..") + .canonicalize() + .expect("workspace root resolves") } fn make_workspace_tempdir() -> PathBuf { @@ -70,7 +73,11 @@ fn read_csv_2d(path: &std::path::Path) -> Array2 { .filter(|l| !l.trim().is_empty()) .map(|l| { l.split(',') - .map(|s| s.trim().parse::().unwrap_or_else(|_| panic!("parse {s:?}"))) + .map(|s| { + s.trim() + .parse::() + .unwrap_or_else(|_| panic!("parse {s:?}")) + }) .collect() }) .collect(); @@ -104,7 +111,11 @@ fn run_matlab_cssd( let didx_path = work.join("discont_idx.csv"); let script_path = work.join("run_parity.m"); - let x_lit: String = x.iter().map(|v| format!("{v:.17e}")).collect::>().join("; "); + let x_lit: String = x + .iter() + .map(|v| format!("{v:.17e}")) + .collect::>() + .join("; "); let n = y.nrows(); let d = y.ncols(); let mut y_lit = String::new(); @@ -147,7 +158,10 @@ fn run_matlab_cssd( if !status.status.success() { let stdout = String::from_utf8_lossy(&status.stdout); let stderr = String::from_utf8_lossy(&status.stderr); - panic!("MATLAB cssd failed (rc={:?}):\nSTDOUT:\n{stdout}\nSTDERR:\n{stderr}", status.status.code()); + panic!( + "MATLAB cssd failed (rc={:?}):\nSTDOUT:\n{stdout}\nSTDERR:\n{stderr}", + status.status.code() + ); } let coefs = read_csv_2d(&coefs_path); @@ -160,7 +174,11 @@ fn run_matlab_cssd( }; let _ = fs::remove_dir_all(&work); - MatlabCssdResult { breaks, coefs, discont_idx } + MatlabCssdResult { + breaks, + coefs, + discont_idx, + } } fn assert_coefs_close(rust: &Array2, matlab: &Array2) { @@ -196,9 +214,16 @@ fn run_parity_case( eprintln!("[{name}] skipping: matlab shim not configured"); return; } - let out_rust = - cssd(Some(x.view()), y.view(), p, gamma, None, pruning_rust, Preconditioning::None) - .expect("rust cssd ok"); + let out_rust = cssd( + Some(x.view()), + y.view(), + p, + gamma, + None, + pruning_rust, + Preconditioning::None, + ) + .expect("rust cssd ok"); let out_matlab = run_matlab_cssd(&x, &y, p, gamma, pruning_matlab); assert_relative_eq!( From 6c98c20e71713070084d7f108a903674011b20ff Mon Sep 17 00:00:00 2001 From: Martin Storath Date: Thu, 7 May 2026 20:10:03 +0000 Subject: [PATCH 11/11] Create explicit venv in CI to fix maturin develop on Windows --- .github/workflows/ci.yml | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index e8c331c..8b04a81 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -41,6 +41,16 @@ jobs: python-version: ${{ matrix.python-version }} - uses: dtolnay/rust-toolchain@stable - uses: Swatinem/rust-cache@v2 + - name: create and activate venv + shell: bash + run: | + python -m venv .venv + if [ -d .venv/Scripts ]; then + echo "$GITHUB_WORKSPACE/.venv/Scripts" >> "$GITHUB_PATH" + else + echo "$GITHUB_WORKSPACE/.venv/bin" >> "$GITHUB_PATH" + fi + echo "VIRTUAL_ENV=$GITHUB_WORKSPACE/.venv" >> "$GITHUB_ENV" - name: install build deps run: pip install maturin pytest numpy scipy matplotlib - name: maturin develop
