GLoMOT: Efficient Online GNN-based Low-Frame-Rate Multi-Object Tracker

AAAI 2026technical

Low-frame-rate (LFR) Multi-Object Tracking (MOT) is crucial for efficient tracking on edge devices, as it significantly reduces computational and storage demands. However, existing trackers struggle in LFR settings due to large temporal gaps, extreme appearance changes, and motion non-linearity. Whi

Tight and fast generalization error bound of graph embedding in metric space

ICML 2023poster

Recent studies have experimentally shown that we can achieve in non-Euclidean metric space effective and efficient graph embedding, which aims to obtain the vertices' representations reflecting the graph's structure in the metric space. Specifically, graph embedding in hyperbolic space has experimen…

Cumulative Stay-time Representation for Electronic Health Records in Medical Event Time Prediction

IJCAI 2022poster

We address the problem of predicting when a disease will develop, i.e., medical event time (MET), from a patient's electronic health record (EHR). The MET of non-communicable diseases like diabetes is highly correlated to cumulative health conditions, more specifically, how much time the patient sp…

Generalization Bounds for Graph Embedding Using Negative Sampling: Linear vs Hyperbolic

NeurIPS 2021poster

Graph embedding, which represents real-world entities in a mathematical space, has enabled numerous applications such as analyzing natural languages, social networks, biochemical networks, and knowledge bases. It has been experimentally shown that graph embedding in hyperbolic space can represent hi…

Generalization Error Bound for Hyperbolic Ordinal Embedding

ICML 2021spotlight

Hyperbolic ordinal embedding (HOE) represents entities as points in hyperbolic space so that they agree as well as possible with given constraints in the form of entity $i$ is more similar to entity $j$ than to entity $k$. It has been experimentally shown that HOE can obtain representations of hiera…
