Pseudocode No The paper does not contain structured pseudocode or algorithm blocks.
Open Source Code No The paper does not provide a direct link to its source code or explicitly state that its code is released.
Open Datasets Yes Gowalla1 dataset includes the world-wide check-in data from February 2009 to October 2010. Foursquare2 dataset includes check-in data from April 2012 to September 2013 within the United States (except Alaska and Hawaii).
Dataset Splits Yes we rank the check-in history of each user in ascending order of the time step and split the dataset D into Dtrain : Dvalidation : Dtest as 8:1:1 according to previous studies [Liu et al., 2016; Chang et al., 2018].
Hardware Specification No The paper does not provide specific hardware details (e.g., GPU/CPU models, memory) used for running its experiments.
Software Dependencies No The paper does not list specific software dependencies with version numbers (e.g., Python, PyTorch, TensorFlow versions).
Experiment Setup Yes The following experimental results of ASPPA are based on the best tuning performance on the validation set (λ = k = 0.001, Ne = 128, Nh = 256, learning rate 0.01 and dropout 0.5 for both datasets). In the training procedure, we leverage the mini-batch SGD algorithm. Specifically, we set the batch size to 1024 according to device capacity.
