Benchmark repository for Sparse Logistic Regression
BenchOpt is a package to simplify and make more transparent and reproducible the comparisons of optimization algorithms. This benchmark tests algorithms to solve the following problem:
\min_w \sum_i \log(1 + \exp(-y_i x_i^\top w)) + \lambda \|w\|_1
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}
Install
This benchmark can be run using the following commands:
$ pip install -U benchopt $ git clone https://github.com/benchopt/benchmark_logreg_l1 $ benchopt run benchmark_logreg_l1
Apart from the problem, options can be passed to benchopt run, to restrict the benchmarks to some solvers or datasets, e.g.:
$ benchopt run benchmark_logreg_l1 -s sklearn -d boston --max-runs 10 --n-repetitions 10
Use benchopt run -h for more details about these options, or visit https://benchopt.github.io/api.html.
