Unsupervised Text Segmentation via Kernel Change-Point Detection on Sentence Embeddings
Mumin Jia, Jairo Diaz-Rodriguez
Unsupervised text segmentation is crucial because boundary labels are expensive, subjective, and often fail to transfer across domains and granularity choices. We propose Embed-KCP…

Consistent Kernel Change-Point Detection under m-Dependence for Text Segmentation
Jairo Diaz-Rodriguez, Mumin Jia
Kernel change-point detection (KCPD) has become a widely used tool for identifying structural changes in complex data. While existing theory establishes consistency under independe…

Dynamics of Spontaneous Topic Changes in Next Token Prediction with Self-Attention
Mumin Jia, Jairo Diaz-Rodriguez
Human cognition is punctuated by abrupt, spontaneous shifts between topics-driven by emotional, contextual, or associative cues-a phenomenon known as spontaneous thought in neurosc…
