Quantum Computing and Machine Learning for Combinatorial Optimisation

Stephane BRESSAN

This project combines quantum computing and machine learning to enhance combinatorial problem-solving. Leveraging Neural Network Quantum States (NNQS) and Quantum Annealing (QA) platforms, it aims to optimize Quadratic Unconstrained Binary Optimization (QUBO) for real-world tasks.

Enhancing Legal Document Services with Accessible and Private LLM Technology

HE Bingsheng

This project aims to transform legal document services by developing a local, privacy-preserving Large Language Model (LLM) technology. The research tackles privacy concerns associated with external server processing, seeking to enhance efficiency, speed, and reliability while overcoming computational constraints.

A Holistic Approach for Scale-Independent Query Processing

CHAN Chee Yong

This project aims to design a holistic approach for scale-independent query processing on big data, addressing critical issues like cost-based optimization, cardinality constraints, and join optimization. The goal is to ensure efficient information retrieval regardless of data size, contributing to advancements in big-data applications' database systems.

NUS Digital Twin for Research and Services

HUANG Zhiyong, HE Bingsheng, Anthony TUNG

This project aims to create a virtual twin of the NUS campus integrating the built and natural environment with static and dynamic data for modelling, visualization, simulation, analysis and AI. By creating a high-fidelity model, it harmonizes diverse data sources, optimizing performance for applications including smart transport, utility planning, climate studies and sustainable campus design.
