Domain Pre-training Impact on Representations

Cesar Gonzalez-Gutierrez, Ariadna Quattoni


Abstract
This empirical study analyzes how the choice of pre-training corpus affects the quality of learned transformer representations. We focus specifically on the representation quality achieved through pre-training alone. Our experiments demonstrate that pre-training on a small, specialized corpus can produce effective representations, and that the effectiveness of combining a generic and a specialized corpora depends on the distributional similarity between the target task and the specialized corpus.
