New MIP approach offers faster change-point detection

By PulseAugur Editorial · [1 sources] ·

A new mixed-integer programming (MIP) approach has been developed for offline multiple change-point detection, framing the problem as a globally optimal piecewise linear fitting task. This method introduces strengthened MIP formulations with linear programming relaxations that offer integral projections onto segment-assignment variables, providing provably tighter relaxations than existing techniques. The framework is also extended to multi-dimensional piecewise linear models with shared change-points, and computational experiments show significant reductions in solution times compared to current state-of-the-art methods.

    Change-Point Detection via Piecewise Linear Fitting Using MIP

    arXiv:2602.11947v2 Announce Type: replace-cross Abstract: We present a new mixed-integer programming (MIP) approach for offline multiple change-point detection by casting the problem as a globally optimal piecewise linear (PWL) fitting problem. Our main contribution is a family o…
