Beer Dataset from Near Infrared Spectroscopy
Description
The beer dataset contains 60 samples published by Norgaard et al. Recorded with a 30mm quartz cell on the undiluted degassed beer and measured from 1100 to 2250 nm (576 data points) in steps of 2 nm. A good playing ground for regression methods starting from spectral intensities.
