• abstract = "The majority of dimension reduction techniques are built upon the optimization of an objective function aiming to retain certain characteristics of the projected datapoints: the variance of the original dataset, the distance between the datapoints or their neighbourhood characteristics, etc. Building upon the optimization-based formalization of dimension reduction techniques, the goal-oriented formulation of projection cost functions is proposed. For the optimization of the application-oriented data visualization cost function, a Multi-gene genetic programming (GP)-based algorithm is introduced to optimize the structures of the equations used for mapping high-dimensional data into a two-dimensional space and to select variables that are needed to explore the internal structure of the data for data-driven software sensor development or classifier design. The main benefit of the approach is that the evolved equations are interpretable and can be used in surrogate models. The applicability of the approach is demonstrated in the benchmark wine dataset and in the estimation of the product quality in a diesel oil blending technology based on an online near-infrared (NIR) analyzer. The results illustrate that the algorithm is capable to generate goal-oriented and interpretable features, and the resultant simple algebraic equations can be directly implemented into applications when there is a need for computationally cost-effective projections of high-dimensional data as the resultant algebraic equations are computationally simpler than other solutions as neural networks",
