Research

Our research focuses on designing AI systems that operate effectively under constrained environments, including limited computation, communication bandwidth, and privacy requirements. We assume execution on edge devices and develop methods that adapt AI behavior to network conditions and real-world application demands. Rather than treating computing, communication, and AI separately, we aim to jointly optimize them in an integrated manner.

Theme1:Foundation - Edge AI & On-device Intelligence

Overview

Adaptive Edge Intelligence (Core)

Objective: To realize intelligent systems that operate directly on devices and adapt to constraints such as computation, and communication.

Novelty: Establish design principles that dynamically optimize models, representations, and computation partitioning based on resource and network conditions.

Methods: Model compression, edge-cloud collaboration, federated learning, and uncertainty-aware inference and control.

Results: Prototypes satisfying real-time performance, computational efficiency, and energy constraints, validated via simulation and small-scale demonstrations.

Next: Extend toward context-adaptive AI that integrates communication and application requirements.

Keywords

Theme2:Network-Aware AI

Overview

Objective: To design AI systems that optimize computation and representation based on dynamic network conditions.

Novelty: Jointly consider communication, inference, and control to enable resilient operation under failures, congestion, and variability.

Methods: Distributed optimization, reinforcement learning, graph neural networks (GNN), and service function chain (SFC) placement.

Results: Quantitative evaluation of latency, reliability, and cost under network constraints, along with systematic design of adaptive policies.

Next: Develop unified frameworks that dynamically optimize computation, communication, and information representation.

Theme3:Real-World Applications

Overview

Objective: To build practical intelligent systems for real-world environments such as AgeTech and IoT under realistic constraints.

Novelty: Map heterogeneous sensor data (e.g., LiDAR, microwave, pressure sensors) into shared semantic representations robust to missing data, non-IID conditions, and privacy constraints.

Methods: Semantic representation learning, privacy-preserving learning, real-time edge inference, and adaptive operation based on network and energy conditions.

Results: Validation through public datasets, simulation, and small-scale prototyping toward real deployment.

Next: Extend toward resilient systems that remain functional under disruptions such as disasters or network congestion.
