Pseudocode Yes Algorithm 1 Zeta Hull Pursuits
Open Source Code No The paper does not contain any explicit statements about releasing source code or links to a code repository for the described methodology.
Open Datasets Yes The MNIST dataset serves as a standard benchmark for machine learning algorithms. The Caltech101 dataset [17] is a widely used benchmark for object recognition systems. The Multi PIE human face dataset is a widely applied benchmark for face recognition [9].
Dataset Splits No The paper specifies training and testing sets for various datasets (e.g., 'The training set has 60000 images and the testing set has 10000 images' for MNIST), but does not explicitly mention a validation set or specific validation split percentages.
Hardware Specification No The paper mentions that computations can be parallelized using a 'multi-core CPU or a modern GPU', but does not provide specific hardware details like model numbers or configurations.
Software Dependencies No The paper mentions using a 'standard ℓ1-regularized projection algorithm (LASSO)' and 'linear SVM' but does not specify any software names with version numbers.
Experiment Setup Yes In all experiments, the parameter z is fixed at 0.05 to guarantee the convergence of the Zeta function. For the A-ZHP algorithm, the parameter s is fixed at 10 and the number of anchor points l is set as 10% of the training set size.
