• Abstract summary: We show that a predictive model can be used to predict future values while forming a latent cluster space. We compare two models on Withing's datasets, M AGMAC LUST which clusters entire time series and DGM$2$ which allows the group affiliation of an individual to change over time.

• Abstract: In healthcare, patient data is often collected as multivariate time series, providing a comprehensive view of a patient's health status over time. While this data can be sparse, connected devices may enhance its frequency. The goal is to create patient profiles from these time series. In the absence of labels, a predictive model can be used to predict future values while forming a latent cluster space, evaluated based on predictive performance. We compare two models on Withing's datasets, M AGMAC LUST which clusters entire time series and DGM${}^2$ which allows the group affiliation of an individual to change over time (dynamic clustering).

  Time series foundation models are pre-trained on large datasets and are able to achieve state-of-the-art performance in diverse tasks. We propose a prompt-tuning-inspired fine-tuning technique, Gen-P-Tuning, that enables us to adapt an existing univariate time series foundation model. We demonstrate the effectiveness of our fine-tuning approach against various baselines on two MIMIC classification tasks, and on influenza-like illness forecasting.
