Reproducibility Variable Result LLM Response
Research Type Experimental We evaluate our method based on Beijing air quality and meteorological data, finding advantages to our model compared with ten baseline approaches.
Researcher Affiliation Collaboration 1School of Information Science and Technology, Southwest Jiaotong University, Chengdu, China 2Microsoft Research, Beijing, China 3Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences
Pseudocode Yes Algorithm 1 ST-MVL Input: Original Data Matrix 𝑀, 𝜔, 𝛼, 𝛽; Output: Final Data Matrix;
Open Source Code Yes The code and datasets have been released at: http://research.microsoft.com/apps/pubs/?id=264768.
Open Datasets Yes We evaluate our model based on two real datasets: air quality and meteorological data in Beijing from 2014/05/01 to 2015/04/30 [Zheng et al., 2015]
Dataset Splits No We partition the 1-year data into two parts, using the 3rd, 6th, 9th and 12th months as a test set and the rest for a training set. The paper does not mention a distinct validation set.
Hardware Specification No The paper does not provide specific details about the hardware used for experiments.
Software Dependencies No The paper does not provide specific software dependencies with version numbers.
Experiment Setup Yes Parameter Settings: We test different 𝛼 for IDW, 𝛽 for SES, and 𝜔 for UCF & ICF, finding a best setting for them, e.g. when 𝛼=4, 𝛽=0.85, and 𝜔=7 achieve the best performance in PM2.5 property.
