Self-renewal machine learning framework for wireless network optimization

We proposed a self-renewal ML (SRML) approach for the optimization of wireless network capacity. The SRML method incrementally improves the throughput maximization of future optimization instances through the design of a data selection algorithm for fine-tuning an application identification model. Our proposed SRML method reduces the computational complexity and achieves a higher solution efficiency.

Bayesian networks and machine learning for COVID-19 severity explanation

We developed a three-stage data-driven approach to distill the hidden information about COVID-19. The first stage employs a Bayesian network structure learning method to identify the causal relationships among COVID-19 symptoms and their intrinsic demographic variables. As a second stage, the output from the Bayesian network structure learning, serves as a useful guide to train an unsupervised machine learning (ML) algorithm that uncovers the similarities in patients’ symptoms through clustering. The final stage then leverages the labels obtained from clustering to train a demographic symptom identification model which predicts a patient’s symptom class and the corresponding demographic probability distribution.

Self-supervised learning approach for accelerating wireless network optimization

In this project, we study the classic wireless multi-commodity network flow problem, where the network-layer routing issue and link-layer scheduling issue are coupled together. We proposed a self-supervised learning paradigm in which the scheduling structures (referring to the independent sets) of historical optimization experiences from a fixed network topology are smartly exploited to facilitate solving new instances with greatly reduced computational overhead.
