Application of Artificial Neural Networks for the Automatic Spectral Classification

Figure 2

The ANNs were trained with LAMOST DR1 dataset using the k-fold cross-validation technique and here the result of one of the 4 training and validation rounds of the GRNN with sigma value = 1 is shown. Dotted line represents the identity where the output (Y) coincides with the target (T).
