Identifying latent state transitions in non-linear dynamical systems

ICLR 2025poster

This work aims to recover the underlying states and their time evolution in a latent dynamical system from high-dimensional sensory measurements. Previous works on identifiable representation learning in dynamical systems focused on identifying the latent states, often with linear transition approxi…

Adaptation Odyssey in LLMs: Why Does Additional Pretraining Sometimes Fail to Improve?

EMNLP 2024main

In the last decade, the generalization and adaptation abilities of deep learning models were typically evaluated on fixed training and test distributions. Contrary to traditional deep learning, large language models (LLMs) are (i) even more overparameterized, (ii) trained on unlabeled text corpora c…

Variational multiple shooting for Bayesian ODEs with Gaussian processes

UAI 2022poster

Recent machine learning advances have proposed black-box estimation of \textit{unknown continuous-time system dynamics} directly from data. However, earlier works are based on approximative solutions or point estimates. We propose a novel Bayesian nonparametric model that uses Gaussian processes to…
