Semi-Supervised Hyperspectral Image Classification with Edge-Aware Superpixel Label Propagation and Adaptive Pseudo-Labeling

The paper introduces a semi‑supervised hyperspectral image classification framework that combines spatial prior information with a dynamic learning mechanism. It proposes an Edge‑Aware Superpixel Label Propagation module to reduce boundary label diffusion and a Dynamic History‑Fused Prediction method to stabilize pseudo‑labels over time. Additionally, an Adaptive Tripartite Sample Categorization strategy is used to hierarchically exploit easy, ambiguous, and hard samples, resulting in improved pseudo‑label quality and learning efficiency. The combined Dynamic Reliability‑Enhanced Pseudo‑Label Framework achieves spatio‑temporal consistency optimization and demonstrates superior performance on four benchmark datasets.

Semi-Supervised Adaptation of Vision-Language Models for Image Classification

The paper introduces Self‑Evolutionary CLIP (SE‑CLIP), a semi‑supervised framework that adapts vision‑language models like CLIP to satellite imagery. SE‑CLIP uses a two‑phase pipeline: an initial warm‑up on a small set of annotated seeds followed by a recursive discovery phase that iteratively selects high‑confidence samples from unlabeled data. A class‑balanced selection strategy is applied to keep the evolving support set balanced, and experiments on the UCM and NWPU benchmarks show that SE‑CLIP outperforms existing semi‑supervised methods.

Pre-train to Gain: Robust Learning Without Clean Labels

The paper proposes a method that first pre‑trains a feature extractor on the target dataset using in‑domain self‑supervised learning (SSL) without labels, then performs standard supervised training on the same noisy dataset. This two‑stage approach eliminates the need for a clean label subset and consistently improves classification accuracy and label‑error detection across synthetic and real‑world noise, especially as noise rates increase. Experiments show that the method matches or surpasses ImageNet and DinoV2 pre‑training, particularly under high noise conditions.
