Research Type Experimental A numerical illustration and a discussion about the proposed method are given in Sections 5 and 6 respectively. In this section we illustrate the results of the previous section on a simple example. We sample n1 = 10^6 points on the sphere for computing the graph Laplacians and we use n = 10^3 points for approximating the norms...

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 No The paper states 'We sample n1 = 10^6 points on the sphere for computing the graph Laplacians and we use n = 10^3 points for approximating the norms ( ˆ h ˆ h ) f 2 2,M.' and 'data points generated uniformly on the sphere S2 in R3', but provides no access information (link, DOI, repository, or citation) for this generated dataset.
Dataset Splits Yes Regarding the first issue, we can approximate 2,M by splitting the data into two samples: an estimation sample X1 for computing the estimators and a validation sample X2 for evaluating this norm. More precisely, given two estimators ˆ hf and ˆ h f computed using X1, the quantity ( ˆ h ˆ h )f 2 2,M/µ(M) is approximated by the averaged sum 1 n2 P x X2 | ˆ hf(x) ˆ h f(x)|2, where n2 is the number of points in X2.
Hardware Specification No The paper does not provide specific hardware details (like exact GPU/CPU models or processor types) used for running its experiments.
Software Dependencies No The paper does not provide specific ancillary software details (e.g., library or solver names with version numbers) needed to replicate the experiment.
Experiment Setup Yes We sample n1 = 10^6 points on the sphere for computing the graph Laplacians and we use n = 10^3 points for approximating the norms... We compute the graph Laplacians for bandwidths in a grid H between 0.001 and 0.8.
