abstract: PI-Change is a prior-informed multiple change point detection method that
  incorporates prespecified plausible change point locations through a time-varying
  penalized likelihood. The method extends multiple change point detection beyond
  purely data-driven segmentation by allowing external knowledge about plausible change
  point locations to enter the objective function; see Jacobs and Chen (2026) <https://doi.org/10.48550/arXiv.2605.01003>.
