Benchmark repository for Non-negative Least Square
==================================================
|Build Status| |Python 3.6+|
Benchopt is a package to simplify and make more transparent and
reproducible the comparisons of optimization algorithms.
The Non-Negative Least Square consists in solving the following program:
$${\\min}_{w \\geq 0} \\frac{1}{2} \\lVert y - Xw \\rVert^2_2$$
where $n$ (or ``n_samples``) stands for the number of samples, $p$ (or ``n_features``) stands for the number of features and
$$y \\in \\mathbb{R}^n, X = [x_1^\\top, \\dots, x_n^\\top]^\\top \\in \\mathbb{R}^{n \\times p}$$
In case a $w$ with negative entries is passed, those entries are set to 0 to evaluate the objective function at a feasible point.
Install
--------
To download and run the benchmark on a few solvers and datasets, use:
.. code-block::
$ pip install -U benchopt
$ git clone https://github.com/benchopt/benchmark_nnls
$ benchopt run benchmark_nnls --config simple_config.yml
Options can be passed to `benchopt run`, e.g. to restrict the benchmarks to some solvers or datasets:
.. code-block::
$ benchopt run benchmark_nnls -s scipy -d leukemia --max-runs 10 --n-repetitions 10
Use `benchopt run -h` for more details about these options, or visit https://benchopt.github.io/api.html.
