Sample-Efficient Optimisation with Probabilistic Transformer Surrogates

no code implementations27 May 2022 Alexandre Maraval, Matthieu Zimmer, Antoine Grosnit, Rasul Tutunov, Jun Wang, Haitham Bou Ammar

First, we notice that these models are trained on uniformly distributed inputs, which impairs predictive accuracy on non-uniform data - a setting arising from any typical BO loop due to exploration-exploitation trade-offs.

Efficient Semi-Implicit Variational Inference

no code implementations15 Jan 2021 Vincent Moens, Hang Ren, Alexandre Maraval, Rasul Tutunov, Jun Wang, Haitham Ammar

In this paper, we propose CI-VI an efficient and scalable solver for semi-implicit variational inference (SIVI).
