Research Type Experimental Extensive experiments show the effectiveness of FC-STGNN on multiple MTS datasets compared to SOTA methods. We examine our method on three different downstream tasks: Remaining Useful Life (RUL) prediction, Human Activity Recognition (HAR), and Sleep Stage Classification (SSC). Specifically, we utilize C-MAPSS (Saxena et al. 2008) for RUL prediction, UCI-HAR (Anguita et al. 2012) for HAR, and ISRUC-S3 (Khalighi et al. 2016) for SSC, following the previous work (Wang et al. 2023a).

Pseudocode No The paper does not contain a clearly labeled 'Pseudocode' or 'Algorithm' block.
Open Source Code Yes The code is available at https://github.com/Frank-Wang-oss/FCSTGNN.
Open Datasets Yes Specifically, we utilize C-MAPSS (Saxena et al. 2008) for RUL prediction, UCI-HAR (Anguita et al. 2012) for HAR, and ISRUC-S3 (Khalighi et al. 2016) for SSC, following the previous work (Wang et al. 2023a).
Dataset Splits Yes For C-MAPSS which includes four sub-datasets, we adopt the pre-defined train-test splits. The training dataset is further divided into 80% and 20% for training and validation. For HAR and ISRUC, we randomly split them into 60%, 20%, and 20% for training, validating, and testing.
Hardware Specification Yes All methods are conducted with NVIDIA Ge Force RTX 3080Ti and implemented by Py Torch 1.9.
Software Dependencies Yes All methods are conducted with NVIDIA Ge Force RTX 3080Ti and implemented by Py Torch 1.9.
Experiment Setup Yes We set the batch size as 100, choose ADAM as the optimizer with a learning rate of 1e-3, and train the model 40 epochs.
