Pseudocode Yes Algorithm 1: Ro He: Robust heterogeneous HAN
Open Source Code No The paper does not provide an explicit statement about releasing source code or a link to a code repository.
Open Datasets Yes Ro He is evaluated on three widely used HG datasets: (1) ACM (Wang et al. 2019a) consists of {Paper (P), Author (A), Subject (S)}... (2) DBLP (Fu et al. 2020) consists of {Author (A), Paper (P), Term (T), Conference (C)}... (3) Aminer (Hu, Fang, and Shi 2019) consists of {Paper (P), Author (A), Reference (R)}...
Dataset Splits No The paper mentions evaluating performance with Micro-F1 metric over test set, but it does not explicitly provide details about training/validation/test splits (e.g., percentages or counts for validation data).
Hardware Specification No The paper does not provide specific details about the hardware used for experiments.
Software Dependencies No The paper does not specify any software names with version numbers.
Experiment Setup Yes Given a target node, we limit adversarial edges with budget = {1, 2, 3} and edge types as P-A for ACM/DBLP and P-R for Aminer. We evaluate the performance with Micro-F1 metric over 500 target nodes, which are randomly sampled from the test set. Parameter Study: We analyze hyper-parameters T which is the number of neighbors to be kept in purifier of HAN-Ro He, under scenarios of Clean and Attack with = {1, 3}.
