Pseudocode No The paper does not contain structured pseudocode or algorithm blocks.
Open Source Code No The paper mentions using 'open source implementation in My Media Lite' for LFM and 'the source code...released by the authors' for HFT, but does not provide specific access to the source code for the methodology described in this paper (RBLT).
Open Datasets Yes To avoid data biases, we randomly selected 80% of each dataset for training, 10% of each dataset for validation and the remaining 10% for testing
Dataset Splits Yes To avoid data biases, we randomly selected 80% of each dataset for training, 10% of each dataset for validation and the remaining 10% for testing
Hardware Specification No The paper does not provide specific hardware details (e.g., GPU/CPU models, memory amounts) used for running its experiments.
Software Dependencies No The paper mentions 'My Media Lite' and 'LDA model' but does not specify version numbers for any software dependencies.
Experiment Setup No The paper mentions minimizing an objective function with stochastic gradient descent (SGD) and using grid search for regularization parameters λ1 and λ2, but it does not provide specific hyperparameter values or detailed training configurations (e.g., learning rate, specific λ values).
