Researchers have introduced a new method for evaluating sentence embedding techniques, called Concept Separation Curves. This approach aims to assess how well embeddings capture sentence meaning without relying on external classifiers or downstream tasks, which can obscure the embedding's true performance. By systematically adding syntactic noise and semantic negations to sentences, the method visualizes the embeddings' stability and ability to differentiate conceptual meaning from surface-level variations.
