Researchers have developed a novel post-hoc embedding alignment technique to improve the performance of compressed transformer models. This method, called the Alignment Adapter (AlAd), uses a small feed-forward network to align token embeddings of a compressed model with those of a reference model. AlAd can be trained after the compressed model is produced, and it has shown performance improvements across various token-level tasks like POS tagging, NER, and extractive question answering, particularly benefiting smaller compressed models.
