Scalable Parameter-Light Spectral Method for Clustering Short Text Embeddings with a Cohesion-Based Evaluation Metric

arXiv — cs.CLTuesday, November 25, 2025 at 5:00:00 AM
  • A new scalable spectral method has been introduced for clustering short text embeddings, addressing the challenge of pre-specifying the number of clusters. This method utilizes an adaptive sampling strategy to construct the Laplacian eigenspectrum based on cosine similarities, allowing for efficient scaling to large datasets while maintaining reliability.
  • This development is significant as it enhances the intrinsic evaluation of cluster quality through the proposed Cohesion Ratio, which quantifies intra-cluster similarity against global similarity, thus providing a more interpretable metric for assessing clustering performance.
  • The introduction of this method reflects ongoing advancements in natural language processing, particularly in clustering techniques. It aligns with broader trends in AI research that seek to improve data handling and analysis, as seen in various frameworks aimed at enhancing model efficiency and performance across different domains.
