Artificial neural networks (not only) in spectroscopy suffer from poor interpretability due to an extensive number of parameters in the model. We propose an entirely new perspective on interpretability through lottery tickets (i.e., tiny, sparse networks with high performance). We will exploit lottery tickets for interpretability as they dramatically reduce the number of parameters and preserve the spatial structure of the data. Also, we will study a potential of lottery tickets for embedded spectroscopic systems (e.g., satellites, rovers).
