Semi-supervised learning (SSL) mitigates this challenge by utilizing unlabeled data alongside limited labeled examples, while the emergence of foundation models (FMs) offers powerful zero-shot capabilities that can further reduce labeling cost. However, directly fine-tuning large FMs is often impractical in resource-constrained settings, and na\\\"ively using their pseudo-labels for unlabeled data can degrade performance due to its unreliablity or domain mismatch with target task.
