Pseudocode Yes Algorithm 1: Joint learning algorithm of Trans2Vec
Open Source Code No The paper states that Trans2Vec 'has been deployed in a map and navigation App' but does not provide any information or links regarding the public availability of its source code.
Open Datasets No We choose two datasets BEIJING and SHANGHAI to test our approach. Both of them are produced based on the map queries and user feedbacks on the Baidu Map, in the corresponding cities from April 1, 2018 till August 20, 2018.
Dataset Splits No We use the data from April through July for training, i.e., learning embeddings, counting historical numbers of rides and training models, and the rest data for testing.
Hardware Specification No The paper does not provide any specific hardware details such as GPU or CPU models, or server configurations used for running the experiments.
Software Dependencies No The paper does not provide specific version numbers for software dependencies or libraries used in the experiments.
Experiment Setup Yes We use the recommended parameters for all baselines, and fixed learning rate α = 0.5 and 0.3 for BEIJING and SHANGHAI, respectively, number d of dimensions to 64, number K of relevance neighbors to 5, and regularizing parameters β1, β2 and γ to 0.1, 0.3 and 0.5, respectively, by default for our BTrans2Vec and Trans2Vec (we will report the sensitivity analysis later).
