Pseudocode No The paper describes methods in prose, tables, and figures, but no explicit pseudocode or algorithm blocks are provided.
Open Source Code No The paper does not contain any statement about releasing source code or a link to a code repository.
Open Datasets No Our dataset contains complete telecommunication records between mobile users using China Telecom in Shanghai, spanning a month from September 3rd, 2016, to September 30th, 2016 (four weeks). The data is provided by China Telecom, the third largest mobile service provider in China.
Dataset Splits No We randomly draw 50% of users and use their calling logs in week 2 to train the classifier. The remaining data is used to test the classifier (50% of data in week 2, and 100% of data in week 3 and week 4). ...We choose the best ℓ2 penalty coefficient using 5-fold cross-validation in training data.
Hardware Specification No The paper does not provide any specific details about the hardware used for experiments.
Software Dependencies No The paper states 'We use ℓ2-regularized logistic regression' for the classifier but provides no specific software version numbers for any tools, libraries, or programming languages used.
Experiment Setup Yes We choose the best ℓ2 penalty coefficient using 5-fold cross-validation in training data.
