Big Data: An Imbalanced Learning Perspective
09/07/2019Intervenant(s) : Haibo He (University of Rhode Island)
Big data has become an important topic worldwide over the past several years. Among many aspects of the big data research and development, imbalanced learning has become a critical component as many data sets in real-world applications are imbalanced, ranging from Internet, finance, social network, to medical and health industry. In general, the imbalanced learning problem is concerned with the performance of machine learning algorithms in the presence of underrepresented data and severe class distribution skews. Due to the inherent complex characteristics of imbalanced data sets, learning from such data requires new understandings, principles, algorithms, and tools to transform vast amounts of raw data efficiently and effectively into information and knowledge representation.
In this talk, I will start with an overview of the nature and foundation of the imbalanced learning problem, and then focus on the state-of-the-art methods and technologies in dealing with the imbalanced data, followed by a systematic discussion on the assessment metrics to evaluate learning performance under the imbalanced learning scenario. I will also introduce the latest research development in our group that we have developed and tested on various imbalanced data sets. Finally, I will highlight the major opportunities and challenges, as well as potential research directions for learning from imbalanced data facing the big data era.
