Title: Robust Semi-supervised Nonnegative Matrix Factorization
Time: 2:00PM-3:00PM
Date: Wednesday 2nd December 2015
Room: P302 LT, Poole House, Talbot Campus
Abstract: Clustering aims to organize a collection of data items into clusters, such that items within a cluster are more “similar” to each other than to those in the other clusters, which has been used in many fields, including machine learning, pattern recognition, image analysis, information retrieval, and bioinformatics. Clustering is usually performed when no information is available concerning the membership of data items to predefined classes. For this reason, it is traditionally seen as part of unsupervised learning. However, in reality, it is often the case that some data information (e.g. labels) is available and could be used to bias the clustering for producing considerable improvements in learning accuracy. Also, data have some new challenges, such as high- dimensionality, sparsity, containing noises and outliers, etc. This motivates us to develop new technology to deal with this kind of complex data. To address all these issues, we propose semi-supervised nonnegative matrix factorization approaches. Experiments carried on well-known data sets demonstrate the effectiveness.
We hope to see you there.












This afternoon Prof. Jonathan Parker introduced the final of three session in the Executive Business Centre under the title ‘Enhancing social life through global social research: Part 3. Social science research in diverse communities’. This session was well attended and coveredwas a wide-range of interesting social science research topics.





Carol Richardson, joint Portsmouth Hospitals NHS Trust and CMMPH’s PhD student, published her latest article ‘On running for supervisor’ in the most recent edition of The Practising Midwife. Carol as Clinical Academic Doctoral Midwife is conducting her thesis research on the topic of pregnancy and obesity. Her PhD is supervised by FHSS Prof. Vanora Hundley, Dr. Carol Wilkins & Prof. Edwin van Teijlingen.
