This research introduces a retrieval-based framework that enables zero-shot and few-shot adaptation in optical network quality-of-transmission estimation without retraining models. By leveraging transferable feature representations, the method outperforms conventional machine learning baselines and contrastive learning approaches on cross-domain datasets. The work advances robust automation for optical networks by decoupling inference from source-specific decision boundaries through global features.
Retrieval-Based Cross-Domain Generalization in Optical Networks via Global Features
arXiv:2608.00044v1 Announce Type: cross Abstract: We propose a retrieval-based framework for crossdomain quality-of-transmission (QoT) estimation that leverages transferable feature representations while avoiding reliance on source-domain-specific decision boundaries. The proposed approach supports both zero-shot and few-shot adaptation without requiring model retraining. Experimental results on cross-domain QoT datasets demonstrate improved generalization performance compared with conventional machine learning baselines and recent contrastive learning approaches, highlighting the potential of retrieval-based inference for robust optical network automation.
