Associate Professor, Electronic & Elect. Engineering

Biography

Anthony Quinn is a senior academic (associate professor) in electronic engineering at Trinity College Dublin. He has had tenure there for twenty four years, and is a Fellow of the College since 2008. He has specialized for nearly thirty years in the development of theory and methods in statistical signal processing. He has an international reputation in Bayesian methodology, i.e. fully probabilistic methods for coping with uncertainty, inspiring optimal design and algorithm flows. He co-authored the first, and highly cited, book (Springer, 2006) on Bayesian methods for the design of signal processing algorithms that can be implemented efficiently (i.e. low energy and computational costs) on computers and specialized hardware. His algorithms have been applied in several practical contexts, notably in signal and image analysis for medical diagnosis and advisory system design. More recently, he has collaborated with his long-time partners in the Czech Academy of Sciences on important problems in Bayesian decision-making and design, with applications in distributed knowledge processing for sensor networks. This work has led to what is probably the first formal Bayesian definition of the transfer learning problem, a key concern in machine learning. He is developing new results in this area currently, as a one-year Fulbright visiting scholar at the renowned Michael Jordan group in Statistics at the University of California, Berkeley. He has recently secured an appointment as research scientist in the Department of Adaptive Systems at the Czech Academy of Sciences (2017-20). Professor Quinn is a committed educator in electrical engineering. He has originated and developed innovative courses in probability (which has been approved for the entire Junior Sophister engineering student cohort in his School) and in statistical signal processing (a module which he developed for the MAI Fifth Year programme in Electronic Engineering, and which was central to the success of the programme in professional accreditation). He has served in many senior roles professionally in his discipline and in his College. He named, lead-authored and developed the E3 and its Strategy in 2012, which received strong endorsement internationally. It has since been adopted as a priority infrastructure project by College. He serves recurrently, and for many years, on committees of several of the best international conferences and funding agencies. He was general chair of the Irish Signals and Systems Conference in 2011, and has acted as external examiner in Ireland and France.

Research Expertise

Description

I am an expert in Bayesian methods (i.e. knowledge representation & inference via probability) for signal processing & machine learning, for 34 years. I work at the interface between electrical engineering (EE), probability & statistics, being among the few internationally with formal grounding jointly in EE, and advanced statistical methodology. My 1-year Fulbright research scholar position ('16-'17) at the renowned Michael Jordan group in the Stats Department, UC Berkeley, reflects this, as do invited lectures (UC Berkeley, UC Santa Cruz and UW Madison), at Université de Bordeaux (2018), Linköping (2008), SUNY NY (1997), etc., as well as international appointments in Prague and Paris (Section 3.2). I seek (a) fuller understanding of the assumptions underlying classical & empirical statistical signal processing solutions (what I call the `auditing property' of Bayesian methods), and (b) new designs arising out of Bayesian analysis (the `prescriptive property'). Major contexts include: (i) Bayesian transfer learning: major recent papers address machine learning and decision making problems, dynamically processing broad knowledge specifications. Designs are randomized, conferring model robustness and replacing selection with exploration strategies. A major context is probabilistic knowledge processing in distributed sensor networks. (ii) Design of recursive computational algorithms. These can be hosted by mobile computing hardware, providing attractive cost-accuracy trade-offs, a central focus of my (widely cited) 2006 Springer monograph, the first in the topic. (iii) Objective assessment of parametric model complexity, leading to optimal parsimony-prediction trade-offs. (iv) Nonparametric Bayesian methods for flexible model-robust inference, obviating finite degrees-of-freedom constraints. Published applications: Bayesian transfer learning allows external data from a patient population to improve the design of radio-iodine therapies for individual thyroid cancer patients. I have also published applications in reconstruction of noisy functional scintigraphic images of the human kidney; a variational Bayes (VB) method for smoothing impulsively corrupted speech; a high-performing VB variant of the state-of-the-art Viterbi algorithm for iterative symbol detection in a mobile digital receiver; and, recently, improved atmospheric pollutant (PM2.5) prediction in India via Bayesian knowledge transfer between nonparametrically modelled sensors. Key research achievements: . My international reputation is recognized by award of a 1-year Fulbright senior research fellowship, hosted by Michael Jordan at UC Berkeley. As part of my Fulbright sabbatical, I delivered a series of invited lectures across America in 2017. . I co-wrote the first book-length treatment (Springer, 2006) of the variational Bayes (VB) approximation in signal processing, which continues to be highly cited. . I was pioneering in migrating Bayesian methods into the arena of signal processing and system analysis, writing the first PhD thesis on the subject (1992) in the Cambridge Signal Processing Laboratory. In recent years, these same Bayesian methods are being widely uptaken within the deep learning toolset. . Important results on performance bounds of Bayesian estimators, contrasting these with classical techniques that have dominated the signal processing state-of-the-art. . New computational flows, implementable on digital computers, for recursive and adaptive signal processing, free from many of the restrictive (linear, Gaussian) assumptions of the implemented state-of-the-art. . I have a long-term (4.5-year) funded appointment as a research scientist in the Czech Academy of Sciences (Section 3.2), employing three postdocs, plus 4 interns from TCD, working on topics ranging from radio-iodine metabolism in thyroid cancer treatment, to pollution prediction in India.
