Beyond Lengthscales: No-regret Bayesian Optimisation With Unknown Hyperparameters Of Any Type

no code implementations2 Feb 2024 Juliusz Ziomek, Masaki Adachi, Michael A. Osborne

Previously proposed algorithms with the no-regret property were only able to handle the special case of unknown lengthscales, reproducing kernel Hilbert space norm and applied only to the frequentist case.

Why Can Large Language Models Generate Correct Chain-of-Thoughts?

no code implementations20 Oct 2023 Rasul Tutunov, Antoine Grosnit, Juliusz Ziomek, Jun Wang, Haitham Bou-Ammar

This paper delves into the capabilities of large language models (LLMs), specifically focusing on advancing the theoretical comprehension of chain-of-thought prompting.

Are Random Decompositions all we need in High Dimensional Bayesian Optimisation?

2 code implementations30 Jan 2023 Juliusz Ziomek, Haitham Bou-Ammar

Learning decompositions of expensive-to-evaluate black-box functions promises to scale Bayesian optimisation (BO) to high-dimensional problems.

Timing is Everything: Learning to Act Selectively with Costly Actions and Budgetary Constraints

no code implementations31 May 2022 David Mguni, Aivar Sootla, Juliusz Ziomek, Oliver Slumbers, Zipeng Dai, Kun Shao, Jun Wang

In this paper, we introduce a reinforcement learning (RL) framework named \textbf{L}earnable \textbf{I}mpulse \textbf{C}ontrol \textbf{R}einforcement \textbf{A}lgorithm (LICRA), for learning to optimally select both when to act and which actions to take when actions incur costs.

Modelling nonlinear dependencies in the latent space of inverse scattering

no code implementations19 Mar 2022 Juliusz Ziomek, Katayoun Farrahi

The conducted meta-analysis also shows a clear practical advantage of such constructed generative models in terms of the efficiency of their training process compared to existing generative models for images.
