Abstract: Gaussian process (GP) for machine learning has been studied over the past two decades. GP models constitute a class of important Bayesian non-parametric models for machine learning and tightly connect to several other salient models, such as support vector machines (SVM), single-layer Bayesian neural networks, regularized-least-squares, relevance vector machines and auto-regressive-moving-average (ARMA) model. GP models have been used in a plethora of applications due to their outstanding performance in function approximation with a natural uncertainty bound. GP models are also deemed as outstanding surrogate function in Bayesian optimization nowadays. In this seminar, I will first give an overview of the GP regression model, followed by some recent advances obtained on universal kernel design and low-cost GP regression model hyper-parameter optimization using the celebrated alternating direction method of multipliers (ADMM). Various applications of GP regression to distributed signal processing and wireless communication will be introduced at the end of the seminar.
