Pseudocode Yes Algorithm 1 Gradient Boosting Histogram Transform (GBHT) for Density Estimation
Open Source Code No The paper does not include an unambiguous statement about releasing the source code for the methodology described, nor does it provide a direct link to a code repository.
Open Datasets No The paper states using 'real datasets from the UCI repository' but does not provide specific links, DOIs, repository names, or formal citations with author/year for accessing these datasets in the main text.
Dataset Splits Yes The number of iterations T is set to be 100 and the other two hyper-parameters smin and smax − smin are chosen from {−2 + 0.5k, k = 0, . . . , 8} and {0.5 + 0.5k, k = 0, . . . , 5}, respectively, by 3-fold cross-validation.
Hardware Specification No The paper does not provide specific hardware details (e.g., GPU/CPU models, processor types, memory amounts) used for running its experiments.
Software Dependencies No The paper does not provide specific ancillary software details, such as library or solver names with version numbers, needed to replicate the experiment.
Experiment Setup Yes We pick smin from the set {−3 + 0.5k, k = 0, . . . , 12} and smax − smin is chosen from the set {0.5 + 0.5k, k = 0, . . . , 5}. For each T we repeat this procedure for 10 times. The number of iterations T is set to be 100 and the other two hyper-parameters smin and smax − smin are chosen from {−2 + 0.5k, k = 0, . . . , 8} and {0.5 + 0.5k, k = 0, . . . , 5}, respectively, by 3-fold cross-validation.
