Module content
This course will introduce pattern recognition techniques with particular emphasis on applications in Chemistry and Biology. The aim is to extract useful information from chemical or biochemical data and techniques for handling multidimensional data together with algorithms for clustering and classifying data will be explained. Datasets from –omics technologies (genomics/proteomics/metabolomics) are typically extremely large, with very many more variables than observations (samples), and require data reduction and feature selection methods. In contrast, the application of pattern recognition and machine learning in computer vision problems requires feature extraction from images and the number of images is usually far greater than the number of variables extracted. Image analysis for automated biological object recognition will be discussed.
