Reproducibility Variable Result LLM Response
Research Type Experimental We also examine the empirical advantage of this new algorithm over the previous algorithm in two test domains, one of explaining conditions generated by a noisy k-DNF rule, and another of explaining conditions that are actually generated by a linear threshold rule.

Pseudocode Yes Algorithm 1 Partial Greedy Algorithm; Algorithm 2 Greedy partial RB; Algorithm 3 Low Deg Partial(X); Algorithm 4 Low Deg Partial 2
Open Source Code No The paper does not provide concrete access to source code for the methodology described.
Open Datasets No The paper describes generating its own data: "In the first domain, there is a planted k-DNF rule that is used to define the condition, subject to some independent random noise." and "In the second domain, the condition is actually defined by a (random) linear threshold rule."
Dataset Splits No The paper mentions training sets ("generated 50,000 examples for each formula, a typical size training set") and test sets ("drew another data set... to estimate the error... on this new data set"; "generated 7,500 additional uniform random examples... to serve as a test set"), but does not specify a validation set or explicit training/validation/test splits with percentages or counts.
Hardware Specification No The paper does not explicitly describe the hardware used to run its experiments.
Software Dependencies No The paper does not provide specific ancillary software details with version numbers.
Experiment Setup Yes For each example x, we independently chose whether to put c(x) = ϕ(x) with 95% probability, or to put c(x) = ϕ(x) with 5% probability. That is, there is a noise rate of 5%.; We supplied Tolerant Elimination the actual noise parameter of 5% and we supplied the Low-Degree algorithm with the actual fraction, 14.25%, of the data that we expect the planted k DNF to explain.; giving the low-degree and naive greedy (baseline) algorithms μ = 10%, 30%, 50%, 70%, 90% and 100%, and giving tolerant elimination a variety of different target error rates; only ϵ = 16% for 2-DNF had any nontrivial effect.
