This paper proposes hyperspectral unmixing algorithms based on autoencoder neural networks for characterizing molecular composition in mixtures using Raman spectroscopy. The algorithms are developed and validated using both synthetic and experimental datasets, demonstrating improved accuracy, robustness, and efficiency compared to standard methods. The authors also apply the approach to complex biological settings, such as volumetric Raman imaging data from a monocytic cell, achieving better biochemical characterization.
Low GrooveSquid.com (original content) Low Difficulty Summary
This paper uses special computer algorithms called autoencoder neural networks to help scientists understand what’s in a mixture of chemicals without having to label them first. It works by taking information from a special kind of light microscope called a Raman spectrometer and using it to figure out what’s in the mixture. The new way of doing things is better than old ways at getting accurate results, and it can even be used to study living cells.
