Researchers have developed a new method called Riemannian Mean Pooling (RMP) to analyze the geometric structure of pre-trained language model embeddings. This technique uses Riemannian geometry and Fréchet aggregation on a symmetric positive definite manifold to extract per-token metrics. Experiments on datasets like CoLA, CREAK, and RTE show that RMP outperforms traditional Euclidean mean pooling, particularly on datasets with complex linguistic structures, suggesting that geometric aggregation plays a key role in improving interpretability and safety.
