SPECTRA: Subspace-Preserving Embedding Calibration, Transport, and Replay for Fully Few-Shot Class-Incremental Audio Classification

SPECTRA is a framework built on a frozen encoder which adds three components, a lightweight trainable adapter that calibrates the generic embeddings to the task, an exemplar-free anti-forgetting scheme, and a transductive optimal-transport refinement of prototypes at test time.
