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 Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

Reproducibility Variable Result LLM Response
Research Type Theoretical Our main contribution in this paper is the design of a simple, nonadaptive and almost optimal query algorithm for testing Fourier sparsity. Theorem 1.2. ... We also show that the query complexity of our algorithm is tight up to logarithmic factors by proving a matching lower bound. Theorem 1.3. ... No experimental results were included in the paper; hence, this question is not applicable. ... Our work does not involve data collection or code execution; hence, this question is not applicable. ... No experimental setup was used in this work; therefore, this item is not applicable. ... As no experiments were conducted, questions of statistical significance or error bars do not arise. ... This work does not involve any experiments requiring computational resources; thus, the question is not applicable.

Pseudocode Yes Algorithm 1: FOURIER-SPARSITY-TESTER Input: Tolerance parameter δ 0, proximity parameter ϵ > 0, sparsity parameter s, and oracle access to a function f : Fn 2 R satisfying ||f||2 = 1 Output: YES if dist2 2 (f, Fs) δ, and NO if dist2 2 (f, Fs) δ + ϵ 1: Choose a random affine subspace A = α + H Fn 2, with dim(H) = Θ log s2/ϵ2 2: Let f A denote the restriction of f to A, and compute an estimate eµ of the sum of squares of top s Fourier coefficients of f A in terms of their absolute values 3: If eµ 1 (δ + ϵ/2) then YES, else NO.
