Pseudocode Yes Algorithm 1 RLMNN via Iteratively Reweighted Method
Open Source Code No The paper does not provide concrete access to source code for the methodology described.
Open Datasets Yes In this section, we evaluate the effectiveness of our method on six standard databases, including LFW database (Huang et al. 2007), Pub Fig database (Kumar et al. 2009), You Tube Face Database (Wolf, Hassner, and Maoz 2011), OSR database (Parikh and Grauman 2011) and Highway Traffic Database (Chan and Vasconcelos 2008).
Dataset Splits Yes The You Tube Face (YTF) (Wolf, Hassner, and Maoz 2011) contains 3,425 videos of 1,595 different persons collected from the You Tube website. In this database, there exist large variations in pose, illumination, and expression in each video sequence. We follow the standard evaluation protocol (Wolf, Hassner, and Maoz 2011) to perform standard, ten-fold, cross validation, pairmatching tests. [...] 30 images for each category are chosen as training data, and other images are used as testing data. The training data is randomly selected and this procedure is repeated 5 times.
Hardware Specification No The paper does not provide specific hardware details (e.g., GPU/CPU models, 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 set λ = 0.1, µ = 0.5, η = 0.8 and ϱ = 0.1 in our method.
