Component analysis and informative feature selection for Raman spectral data
The application of machine learning methods to Raman spectral data analysis allows constructing new data models, but the relations between input features and output remain hidden. Informative feature selection (IFS) methods are used to find latent relations in complex data models. In this work, we investigate different types of IFS, such as wrapper-based and embedded methods, and illustrate their advantages and limitations in application to experimental Raman spectral data.
