Duties and Responsibilities
- Research and Teaching
- Moderator MSc Big Data Analytics (IIT – SL)
- PhD in Informed Selection of Training Examples for Knowledge Refinement, Robert Gordon University (2001)
Nirmalie’s research interests include both theoretical and practical aspects of machine learning and intelligent systems with particular focus on Case-based Reasoning (CBR), Text Mining and Machine Learning. Current application focus is on digital health and algorithms for self-management and intervention.
The underlying aim of her research is to reduce the demand on manual intervention through the development of knowledge-rich representations for intelligent monitoring and decision support systems that reason with data, text and multimedia content. A common theme applicable across all content is to exploit similarity knowledge for effective modelling and semantic indexing.
She is an executive member of the British Computer Society’s Specialist Group on AI since 2002 and was editor of their Expert Update magazine (2005-2010). She has organised many research workshops on textualCBR, webCBR, SocialMedia Mining and more recently on Evolving systems and Deep Learning. She was also chair of the international CBR conference in 2011. Externally, Nirmalie has been a member of the programme committees of ECCBR, ICCBR, ECML/PKDD, IJCAI and FLAIRS. She also pioneers the cause for women in computing and co-chaired the Scottish women in computing research and networking 2015 event in Aberdeen. She currently has several PhD and funded research projects related to knowledge modelling and representation from time-series and social media data.
