Pseudocode Yes Algorithm 1 Model parameter learning procedure
Open Source Code No No explicit statement or link providing access to the source code for the methodology described in the paper.
Open Datasets Yes Two real-world online transactional datasets are used for the experiments: (1) Tmall2 released by IJCAI-15 competition, which recorded the purchased baskets from each anonymous user on Tmall platform (The Chinese version of Amazon) in six months. Each basket is associated with a purchase date with no timestamp for each item inside transaction; and (2) Tafeng3 released on Kaggle, which contains the transactional data of a Chinese grocery store generated in four months, whose format is similar to Tmall. Both datasets are commonly used to test the performance of next-basket prediction (Yu et al. 2016; Guidotti et al. 2018). 2https://tianchi.aliyun.com/dataset/data Id=42 3https://www.kaggle.com/chiranjivdas09/ta-feng-grocerydataset
Dataset Splits Yes Second, we make three training-test splits on the sequence instance set by randomly selecting 20%, 30% and 40% of the instances whose target basket happens in the last 30 days respectively for test while others for training. The number of channels m is set to 3 by tuning on the validation set.
Hardware Specification No No specific hardware details (e.g., GPU/CPU models, memory) are provided for running the experiments.
Software Dependencies No The paper mentions 'Our model is implemented using Tensorflow 1.4.' but does not provide any other software dependencies with version numbers.
Experiment Setup Yes The initial learning rate is empirically set to 0.001 and the batch size is set to 50. In our model, the dimensions of item embeddings and intention states are empirically set to 100. The number of channels m is set to 3 by tuning on the validation set.
