Dissertation & Research

Collective Matrix Factorization

Expanding Boolean MF to the joint-factorization of multiple binary tables.

Acoustic Sensing for Indoor Localization

A joint work with NCS that applies ultrasound fingerprinting to indoor localization.

Multi-agent Reinforcement Learning for UAV Collision Avoidance

An EE5001 project. The main contribution is the development of an OpenAI Gym environment that is friendly for applying multi-agent RL algorithms.
