Pseudocode Yes Algorithm 1: t-th Step Constrained Beam Search ... For clarity, Algorithm 1 provides the i-th CBS step process.
Open Source Code No The paper does not provide any statements about making its source code publicly available, nor does it include a link to a code repository for the methodology described.
Open Datasets Yes In our experiments, we use the dataset released by Li et al. (2021b), which has already been labeled with explicit and implicit sentiment.
Dataset Splits No The paper mentions 'train' and 'test' datasets in Table 1 and discusses training process details, but it does not specify explicit validation dataset splits (percentages or counts) or reference predefined validation splits.
Hardware Specification No The paper does not provide specific details about the hardware (e.g., GPU models, CPU types, memory amounts) used to run the experiments.
Software Dependencies No The paper mentions models like T5 and BERT, but it does not provide specific version numbers for software dependencies (e.g., Python, PyTorch, TensorFlow, or specific library versions) needed for reproducibility.
Experiment Setup Yes In the training process, we set the learning rate as 5 10 5 (Restaurant) and 2 10 5 (Laptop). The batch size is 4 (Restaurant) and 8 (Laptop). We set the training epoch as 15 for both datasets. We set kc=2 in data selection and kn=4 for Unlikelihood Contrastive Regularization. For Constrained Beam Search, we select V =6 and z=3.
