arXiv:2511.16084v3 Announce Type: replace-cross Abstract: Hyperspectral image (HSI) classification typically involves large-scale data and computationally intensive training, which limits the practical deployment of deep learning models in real-world remote sensing tasks. This study introduces SpectralTrain, a universal, architecture-agnostic training framework that enhances learning efficiency by integrating curriculum learning (CL) with principal component analysis (PCA)-based spectral downsampling. By gradually introducing spectral complexity while preserving essential information, Spectral
The increasing complexity of AI models and the demand for practical deployment in remote sensing necessitate more efficient training frameworks for large-scale data like hyperspectral images.
This development addresses a key hurdle for real-world remote sensing applications by making deep learning models for hyperspectral image classification more computationally feasible and robust.
The proposed framework, SpectralTrain, potentially lowers the computational barrier for deploying advanced AI in remote sensing, enabling more widespread and practical use of deep learning for HSI analysis.
