Few-Shot Learning Patterns in Financial Time-Series for Trend-Following Strategies

2 code implementations16 Oct 2023 Kieran Wood, Samuel Kessler, Stephen J. Roberts, Stefan Zohren

To deal with such situations, we propose a novel time-series trend-following forecaster that can quickly adapt to new market conditions, referred to as regimes.

On Sequential Bayesian Inference for Continual Learning

1 code implementation4 Jan 2023 Samuel Kessler, Adam Cobb, Tim G. J. Rudner, Stefan Zohren, Stephen J. Roberts

Sequential Bayesian inference can be used for continual learning to prevent catastrophic forgetting of past tasks and provide an informative prior when learning new tasks.

Efficient Adapter Transfer of Self-Supervised Speech Models for Automatic Speech Recognition

1 code implementation7 Feb 2022 Bethan Thomas, Samuel Kessler, Salah Karout

In this paper we propose applying adapters to wav2vec 2. 0 to reduce the number of parameters required for downstream ASR tasks, and increase scalability of the model to multiple tasks or languages.

Hierarchical Indian Buffet Neural Networks for Bayesian Continual Learning

no code implementations4 Dec 2019 Samuel Kessler, Vu Nguyen, Stefan Zohren, Stephen Roberts

We place an Indian Buffet process (IBP) prior over the structure of a Bayesian Neural Network (BNN), thus allowing the complexity of the BNN to increase and decrease automatically.

Practical Bayesian Learning of Neural Networks via Adaptive Optimisation Methods

1 code implementation8 Nov 2018 Samuel Kessler, Arnold Salas, Vincent W. C. Tan, Stefan Zohren, Stephen Roberts

We introduce a novel framework for the estimation of the posterior distribution over the weights of a neural network, based on a new probabilistic interpretation of adaptive optimisation algorithms such as AdaGrad and Adam.
