| Pseudocode | No | The paper does not contain structured pseudocode or algorithm blocks. |
| Open Source Code | No | The paper does not provide concrete access to source code for the methodology described. |
| Open Datasets | Yes | The real dataset is the Air Quality Index (AQI) dataset [Mei et al., 2014]. |
| Dataset Splits | Yes | We estimate the risk at (n0, n1) by crossvalidating the set of projection coefficients and calculating the loss of the estimate, and taking the mean over the 100 instances of Y0 and Y1. ... We also plot the leave-one-out error for each task (loo-1 through 4)... |
| Hardware Specification | No | The paper does not provide specific hardware details used for running its experiments. |
| Software Dependencies | No | The paper does not provide specific ancillary software details with version numbers. |
| Experiment Setup | Yes | We consider the cosine basis: '0(x) = 1, 'k(x) = √2 cos(πkx), ∀ k ≥ 1. ... We define f0(x) PM k=0 a(0) k 'k(x), by generating the projection coefficients a(0) k , M = 500. ... Specifically we consider n1 ∈ {15, 20, . . . , 50} and n0 = n2 1 . ... The risk estimation was performed for the values of γg ∈ {1.25, 1.75, 2.25} and γ0 = 1, keeping f0 constant throughout and changing g per value of γg (see Fig.3 (b-d)). ... The results are averaged over 20 experiments. |
