METALIGHT (02605.HK): Co-Authored Research Paper Accepted to the Applied Data Science Track of KDD 2026

HONG KONG, June 16, 2026 /PRNewswire/ -- MetaLight Inc. ("MetaLight" or the "Company"; Stock Code: 02605.HK), a public transit information service provider powered by time series data analytics and AI technology, today announced that a peer-reviewed research paper co-authored with Peking University and other institutions has been accepted to the Applied Data Science (ADS) Track of KDD 2026. Titled "A Data-driven Route Segmentation Framework for Time-of-Arrival Estimation Service," the paper's authors are affiliated with Peking University, MetaLight HK Limited (a member of the Group) and other institutions, and its first author is from Peking University; the Company's Chairman and CEO, Dr. Sun Xi, is a co-author. It addresses route segmentation — a previously underexplored step in bus arrival-time estimation (ETA); the Company's team, drawing on its Chelaile platform, provided the real-world data and the online deployment environment for the work.

KDD (the ACM SIGKDD Conference on Knowledge Discovery and Data Mining), organized by ACM SIGKDD, is rated a Class A recommended conference by the China Computer Federation (CCF) and will be held in Jeju, South Korea, from August 9 to 13, 2026. Accepted in the track's second review cycle (Cycle Two), the paper will be included in the proceedings and presented at the conference by its authors.

In bus ETA, a route is typically divided into segments using predefined markers such as intersections, with traffic data aggregated accordingly. Coarse segmentation can blur fine-grained differences in traffic conditions along the same route and constrain prediction accuracy. The research instead draws on large-scale, fine-grained vehicle trajectory data to segment routes so that each segment corresponds to a relatively stable traffic regime, characterizing real traffic variation along a route more precisely.

In offline evaluations covering over a thousand routes and more than a million trajectories, the method outperformed commonly used route-segmentation strategies. In a one-week online evaluation on the Chelaile service across two cities, it reduced storage usage by approximately 90% and CPU usage by approximately 25% at comparable prediction accuracy.

Prior ETA research has focused largely on the prediction model itself, with less attention to how a route is segmented and how its data is organized; this work indicates that this step is just as important to prediction accuracy and operational efficiency. In the Company's bus ETA service, the approach has materially lowered storage and compute requirements at comparable accuracy, making the large-scale online service lighter to run.

Beyond the work accepted to KDD 2026, MetaLight has in recent years also co-authored papers in temporal point processes (with Renmin University of China, Shanghai Jiao Tong University and Fudan University, accepted to AAAI 2026) and model merging (with Shanghai Jiao Tong University and the Shanghai Artificial Intelligence Laboratory, accepted to IJCNN 2025).

A representative of MetaLight said, "This work benefited from the collaboration of our team with Peking University and other partners. We care more about whether technology solves concrete problems in real-world settings, and we also hope to foster an internal culture of active learning and continuous evolution; we will keep building our foundational technology steadily, through long-term investment and collaboration."
