Ultraviolet stellar spectral classification using a multilevel tree neural network

Gupta, R.; Gulati, R. K.; Gothoskar, P. +1 more

Here we present a pattern classification technique based on an Artificial Neural Network (ANN) in a multi-level tree configuration to classify ultraviolet stellar spectra from the IUE Low-Dispersion Spectra Reference Atlas. Preliminary results of this technique show that 94% of the spectra have been classified correctly with an accuracy of one sub…
