KITS: Inductive Spatio-Temporal Kriging with Increment Training Strategy

AAAI 2025technical

Sensors are commonly deployed to perceive the environment. However, due to the high cost, sensors are usually sparsely deployed. Kriging is the tailored task to infer the unobserved nodes (without sensors) using the observed nodes (with sensors). The essence of kriging task is transferability. Recen…

TraffiDent: A Dataset for Understanding the Interplay Between Traffic Dynamics and Incidents

NeurIPS 2025poster

Long-separated research has been conducted on two highly correlated tracks: traffic and incidents. Traffic track witnesses complicating deep learning models, e.g., to push the prediction a few percent more accurate, and the incident track only studies the incidents alone, e.g., to infer the incident…

Non-Neighbors Also Matter to Kriging: A New Contrastive-Prototypical Learning

AISTATS 2024poster

Kriging aims to estimate the attributes of unseen geo-locations from observations in the spatial vicinity or physical connections. Existing works assume that neighbors’ information offers the basis for estimating the unobserved target while ignoring non-neighbors. However, neighbors could also be qu…

A GPU Based Parallel Genetic Algorithm for the Orientation Optimization Problem in 3D Printing

ICRA 2019poster

The choice of model orientation is a very important issue in Additive Manufacturing (AM). In this paper, the model orientation problem is formulated as a multi-objective optimization problem, aiming at minimizing the building time, the surface quality, and the supporting area. Then we convert the pr…
