🔬 Research Internship Position

Role: Master’s Research Intern – Differentiable solvers for time series segmentation

Location: Université Rennes or École Normale Supérieure (ENS), Paris, France
Host Institution: Université Rennes or Inria Paris & ENS-PSL (VALDA Team)
Duration: 6 months (Flexible)
Project: Differentiable solvers for time series segmentation

Position Overview

Time series segmentation (change-point detection, piecewise approximation, regime discovery) relies on discrete optimization that is non-differentiable, blocking its use as a layer in trainable pipelines. Smoothing a fixed-grid dynamic program is well understood; the real obstacle is model selection, since the optimizer also chooses how many segments to use. This internship asks whether that segment-count decision can itself be made differentiable, end-to-end.
