Targeting High Productivity Workforces via Data-Centric Transfer Optimization in the Internet Era

Professor Ong Yew-Soon

Nanyang Technological University

Project Description

This project aims at developing a novel computational framework that can adaptively re-use the knowledge across multiple machines potentially communicating via internet, to enhance the productivity in problem-solving. The developed framework comprises a class of optimization algorithms which are capable of automatically transferring knowledge across problem-solving tasks and by which the complicated real-world problems can be efficiently tackled. Different from the optimizers in the existing multitudinous Bayesian frameworks which are computationally demanding and prevailingly applicable in continuous search space, the optimization algorithms considered by the proposed framework are constraint-free in search space, and rely on nature-inspired, derivative-free, population-based search strategies which require little domain expertise on the user’s side. Besides, the proposed framework is significantly flexible in model selection and combination, and is highly parallelizable due to its emphasis on population-based search. The considered class of algorithms is regarded as a potential shortcut through which artificial general intelligence is achieved.

Research Technical Areas

Heuristic search and optimization

Machine learning

Search and constraint satisfaction

Benefits to the society

The proposed project may significantly improve the productivity of real-world problem-solving and autonomous decision-making through human-like knowledge transfer across problems.

The class of optimization algorithms considered by the project may impact a wide range of real applications, such as smart logistic systems, supply chain management, path planning of autonomous vehicles, automatic traffic signal control, design of smart charging strategies for electrical vehicles, optimization of smart grids, and advanced materials manufacturing, which align with the Smart Nation Initiative of Singapore.
