Aiding classification of gene expression data with feature selection: a comparative study

Shen, Qiang; Shang, Changjing (2006)

This paper presents an application of supervised machine learning approaches to the classification of the yeast S. cerevisiae gene expression data. Established feature selection techniques based on information gain ranking ...
Aiding neural network based image classification with fuzzy-rough feature selection

Shang, Changjing; Shen, Qiang (0, 2008)

This paper presents a methodological approach for developing image classifiers that work by exploiting the technical potential of both fuzzy-rough feature selection and neural network-based classification. The use of ...
Effective Feature Selection for Mars McMurdo Terrain Image Classification

Barnes, David Preston; Shang, Changjing; Shen, Qiang (2009)

This paper presents a novel study of the classification of large-scale Mars McMurdo panorama image. Three dimensionality reduction techniques, based on fuzzy-rough sets, information gain ranking, and principal component ...
Extending Data Reliability Measure to a Filter Approach for Soft Subspace Clustering

Shen, Qiang; Shang, Changjing; Iam-On, Natthakan; Boongoen, Tossapon (2011-12-12)

The measure of data reliability has recently proven useful for a number of data analysis tasks. This paper extends the underlying metric to a new problem of soft subspace clustering. The concept of subspace clustering has ...
