Pseudocode Yes Algorithm 1: BASICSTREAMING; Algorithm 2: HISTAPPROX; Algorithm 3: HISTSTREAMING
Open Source Code No The paper does not provide any concrete access information for open-source code.
Open Datasets Yes DBLP. We construct a representative author selection problem on the DBLP dataset (DBLP 2018), which records the meta information of about 3 million papers, including 1.8 million authors and 5,079 conferences from 1936 to 2018. Stack Exchange. We construct a hot question selection problem on the math.stackexchange.com website (Stack Exchange 2018). The dataset records about 1.3 million questions with 152 thousand commenters from 7/2010 to 6/2018.
Dataset Splits No The paper does not provide specific train/validation/test dataset splits.
Hardware Specification No The paper does not provide specific hardware details used for running its experiments.
Software Dependencies No The paper does not provide specific software dependencies with version numbers.
Experiment Setup Yes We run the three proposed algorithms for 100 time steps and maintain a set with cardinality k = 10 at every time step. We set ϵ = 0.1.
