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..

Research Type Experimental 4.4 Experiments. Figure 1: A comparison of centralized FEDUCB on 3 different axes. Fig. (A) describes the variation in asymptotic per-agent regret for varying privacy budget ε (where δ = 0.1); (B) describes the effect of n in private (solid) vs. non-private (dashed) settings; (C) describes the effect of d in per-agent regret in the private setting (n = O(M log T), ε = 1, δ = 0.1). Experiments averaged over 100 runs.

Open Source Code No No statement regarding open-source code availability or links to repositories was found.
Open Datasets No For any d, we randomly fix θ Bd(1). Each Di,t is generated as follows: we randomly sample K d2 actions x, such that for K 1 actions 0.5 x, θ 0.6 and for the optimal x , 0.7 x , θ 0.8 such that 0.1 always. yi,t is sampled from Ber( xi,t, θ ) such that E[yi,t] = xi,t, θ and |yi,t| 1.
Dataset Splits No The paper describes generating synthetic data for a sequential learning problem but does not specify traditional train/validation/test dataset splits.
Hardware Specification No No specific hardware details (e.g., GPU/CPU models, memory) used for running experiments were provided.
Software Dependencies No No specific software dependencies with version numbers were mentioned.
Experiment Setup Yes For all experiments, we assume L = S = 1. For any d, we randomly fix θ Bd(1). Each Di,t is generated as follows: we randomly sample K d2 actions x, such that for K 1 actions 0.5 x, θ 0.6 and for the optimal x , 0.7 x , θ 0.8 such that 0.1 always. yi,t is sampled from Ber( xi,t, θ ) such that E[yi,t] = xi,t, θ and |yi,t| 1. Results are in Fig. 1, and experiments are averaged on 100 trials. In this setting, we set n = O(M log T), d = 10 (to balance communication and performance), and plot the average per-agent regret after T = 10^7 trials for varying M and ε, while keeping δ = 0.1.
