Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in [1].

Reproducibility Variable Result LLM Response
Research Type Experimental Finally, we complement our theoretical results with experimental evaluation of our algorithms. Our experiments reveal that that the solution of regression under the Orlicz norm induced by Huber loss is much better than the solution given by regression under โ„“1 or โ„“2 norms, under natural noise distributions in practice. We also perform experiments for Orlicz regression with different Orlicz functions G and show their behavior under different noise settings, thus exhibiting the ๏ฌ‚exibility of our framework.

Pseudocode Yes Algorithm 1 Linear regression with Orlicz norm G
Open Source Code No The paper does not provide any statements about the availability of open-source code for the described methodology.
Open Datasets Yes Then, we run experiments on real datasets diabetes and glass in UCI repository(Bache & Lichman, 2013).
Dataset Splits No The paper mentions using simulated data and real datasets but does not provide specific details on training, validation, or test splits (e.g., percentages, sample counts, or citations to standard splits).
Hardware Specification No The paper does not provide specific hardware details (e.g., GPU/CPU models, memory) used for running the experiments.
Software Dependencies No The paper states 'We use MATLAB s linprog to solve โ„“1 regression.' However, it does not specify version numbers for MATLAB or the linprog function, which is insufficient for reproducible software dependencies.
Experiment Setup Yes We chose the parameter ฮด to be 0.75. In all the simulations, we generate matrix A Rn d, ground truth x Rd, and b to be Ax plus some particular noise. We experiment with two n, d combinations, i) n = 200, d = 10 ii) n = 100, d = 75, and 3 noise setting with i) Gaussian noise ii) sparse noise and iii) mixed noise (addition of i) and ii)), altogether 2 3 = 6 setting.
