Attention-enhanced residual autoencoder for NIR spectral feature extraction and classification of grain varieties

Accurate identification of grain cultivars is critical for improving crop yields, streamlining agricultural workflows, and ensuring global food security. Near-infrared (NIR) spectroscopy offers a rapid, non-destructive solution for grain classification. However, its effectiveness hinges on extractin...
