Overview

This page is dedicated to the research activities of Hui Wang and his team at Queen's University Belfast .

Discovery AI refers to the area of artificial intelligence that is focused on uncovering new knowledge including novel insights, signatures (such as biomarkers), causal relationships, and hypotheses across various fields including healthcare, science, and law. Key components of Discovery AI include machine learning and deep learning, natural language processing, and causal inference. For example, AI models can analyse genomic and proteomic data to identify novel biomarkers for diseases like cancer. AI-powered tools like IBM Watson can sift through scientific papers to suggest new, unexplored research directions. AI systems can analyse legal texts to discover relevant case laws, precedents, and compliance requirements that were not previously considered. AI models can analyse epidemiological data to understand novel causal factors behind virus spread.

In Discovery AI Lab at Queen's University Belfast , we take a probabilistic approach to discovery AI, using probability distributions to enable discovery AI.

Research programmes

In our Lab, we take a probabilistic approach to discovery AI, using Contextual Probability to enable discovery AI. Thus our work is categorised into two programmes: Contextual Probability and Discovery AI.

  • Contextual Probability
    • ▸ What is it? Contextual Probability (CP) is a perceptionist probability. CP is an interpretation of probability that is distinct from the frequentist and Bayesian approaches. In this perception-based framework, the probability distribution P is transformed into a new probability G based on the context in which the probability is observed or perceived. Unlike frequentist probability, which relies on long-run frequencies, and Bayesian probability, which incorporates prior beliefs and evidence, contextual probability approximates P via contexts or neighbourhoods.
