报告摘要:Big Data is a hot term used to characterise today’s digital world. Data is being generated in large quantity and velocity, and data is complex due to variety – from structured (e.g. measurements), semi-structured (e.g. web pages), to unstructured (e.g. text, video). One of the challenges Big Data presents is how to get machines to understand data. If we could understand text, we could summarise it or answer questions. If we could understand video, we could detect events for surveillance purpose. Machine Understanding is an emerging field of study that is aimed at tackling the challenging problem of getting machines to understand data in a modern way, one that utilises recent advances in areas such as computational semantics and ontology, focuses on common `understanding’ operations that can be specialised for different types of data.
       In this talk, Professor Hui Wang will present his work on knowledge-supported learning as an approach to machine understanding. He will demonstrate a journey from Lattice Machine to Contextual Probability to Neighbourhood Counting Kernel, leading to a new approach to machine learning where learning from data is supported by existing knowledge. He will then present a case study on machine understanding in the context of a project.
