Reproducibility Variable Result LLM Response
Research Type Experimental Competitive rates are demonstrated for kernel density estimation; and ε-differential privacy is achieved for a broader class of support vector machines than known previously. ... In Figure 1 we display the utility (averaged over 1000 repeats) of the Bernstein mechanism (k = 20) on 5000 points drawn from a mixture of two normal distributions N(0.5, 0.02) and N(0.75, 0.005) with weights 0.4, 0.6, respectively. ... Figure 2 depicts SVM learning with RBF kernel (C = σ = 1) on 1500 each of positive (negative) Gaussian data with mean [0.3, 0.5] ([0.6, 0.4]) and covariance [0.01, 0; 0, 0.01] (0.01 [1, 0.8; 0.8, 1.5]) and demonstrates the mechanism’s uniform approximation of predictions, best seen geometrically with the classifier’s decision boundary.

Pseudocode Yes Algorithm 1 The Bernstein mechanism
Open Source Code No The paper does not provide an explicit statement or link to open-source code for the methodology described.
Open Datasets No The paper mentions generating synthetic data for examples (e.g., "5000 points drawn from a mixture of two normal distributions" for KDE, and "1500 each of positive (negative) Gaussian data" for SVM), but it does not provide access information (link, citation, repository) for these or any other public datasets.
Dataset Splits No The paper mentions using training data but does not specify any training/validation/test splits, percentages, or methodology for data partitioning for reproducibility.
Hardware Specification No The paper does not provide any specific details about the hardware used for running experiments.
Software Dependencies No The paper does not provide specific version numbers for any software dependencies or libraries used.
Experiment Setup Yes Figure 2 depicts SVM learning with RBF kernel (C = σ = 1)
