A kutatási téma leírása:
One of the most important topics in modern chemometric research is the fair comparison of existing methods and algorithms. To select the best analytical technique or model for a given purpose is a straightforward aim of our research project. Similarity measures (correlation coefficients: Pearson, Kendall, Spearman, concordant) and on a reversed scale dissimilarity measures (distances: Euclidean, Manhattan, Mahalanobis, etc.) are to be used, but the results are generally different even in case of proper data-preprocessing (standardization, normalization range scaling, etc.). The procedure based on sum of (absolute) ranking differences developed in our laboratory is suitable for a fair comparison of methods, models features. It can be established, which similarity measure should be used and under which circumstances. Different data sets will be used for validation of novel methods and demonstrate the applicability and usefulness of novel techniques.
