Research Type Experimental 8. Experiments, We plot in Figure 2 the mean value of c Wε T 2(µi, νi) depending on ε, In Figure 3, we visualize the effect of the regularization ε on the ground cost cε itself, We use multidimensional scaling on the adversarial cost matrix cε (with distances between points from the same measures unchanged) to recover points in R2.

Pseudocode Yes Algorithm 1 Projected (sub)Gradient Ascent for Nonnegative Adversarial Cost and Algorithm 2 Randomized (Block) Coordinate Ascent for sequential SRW
Open Source Code No No statement regarding the release of source code or a link to a code repository was found.
Open Datasets No We consider 20 measures (µi)i=1,...,10, (νj)j=1,...,10 on the red-green-blue color space identified with X = [0, 1]3. Each measure is a point cloud corresponding to the colors used in a painting, divided into two types: ten portraits by Modigliani (µi, i M) and ten by Schiele (νj, j S). (No concrete access information for these specific datasets provided).
Dataset Splits No No specific dataset split information (percentages, counts, or predefined splits) for training, validation, or testing is provided.
Hardware Specification No No specific hardware details (exact GPU/CPU models, processor types, memory amounts, or detailed computer specifications) are provided for running experiments.
Software Dependencies No No specific ancillary software details (e.g., library or solver names with version numbers) are provided.
Experiment Setup No The paper mentions 'learning rate lr' and 'MAXITER' in the algorithms, and 'projected SGD' but does not provide concrete hyperparameter values or specific training configurations (e.g., specific learning rate value, number of epochs, batch size).
