Approximate Nearest Neighbour Search on Dynamic Datasets: An Investigation

1 code implementation30 Apr 2024 Ben Harwood, Amir Dezfouli, Iadine Chades, Conrad Sanderson

For online feature learning, the Scalable Nearest Neighbours method is faster than baseline for recall rates below 75%.

Statistically Efficient Bayesian Sequential Experiment Design via Reinforcement Learning with Cross-Entropy Estimators

no code implementations29 May 2023 Tom Blau, Iadine Chades, Amir Dezfouli, Daniel Steinberg, Edwin V. Bonilla

We propose the use of an alternative estimator based on the cross-entropy of the joint model distribution and a flexible proposal distribution.

Bayesian Optimisation for Mixed-Variable Inputs using Value Proposals

no code implementations10 Feb 2022 Yan Zuo, Amir Dezfouli, Iadine Chades, David Alexander, Benjamin Ward Muir

Many real-world optimisation problems are defined over both categorical and continuous variables, yet efficient optimisation methods such asBayesian Optimisation (BO) are not designed tohandle such mixed-variable search spaces.

Optimizing Sequential Experimental Design with Deep Reinforcement Learning

1 code implementation2 Feb 2022 Tom Blau, Edwin V. Bonilla, Iadine Chades, Amir Dezfouli

Bayesian approaches developed to solve the optimal design of sequential experiments are mathematically elegant but computationally challenging.
