Flash Interpretability: Decoding Specialised Feature Neurons in Large Language Models with the LM-Head

Harry J Davies

Large Language Models (LLMs) typically have billions of parameters and are thus often difficult to interpret in their operation. In this work, we demonstrate that it is possible to…

Targeted Angular Reversal of Weights (TARS) for Knowledge Removal in Large Language Models

Harry J. Davies, Giorgos Iacovides, Danilo P. Mandic

The sheer scale of data required to train modern large language models (LLMs) poses significant risks, as models are likely to gain knowledge of sensitive topics such as bio-securi…

In-ear ECG Signal Enhancement with Denoising Convolutional Autoencoders

Edoardo Occhipinti, Marek Zylinski, Harry J. Davies +5

The cardiac dipole has been shown to propagate to the ears, now a common site for consumer wearable electronics, enabling the recording of electrocardiogram (ECG) signals. However,…

Interpretable Pre-Trained Transformers for Heart Time-Series Data

Harry J. Davies, James Monsen, Danilo P. Mandic

Decoder-only transformers are the backbone of the popular generative pre-trained transformer (GPT) series of large language models. In this work, we employ this framework to the an…

A Deep Matched Filter For R-Peak Detection in Ear-ECG

Harry J. Davies, Ghena Hammour, Marek Zylinski +2

The Ear-ECG provides a continuous Lead I electrocardiogram (ECG) by measuring the potential difference related to heart activity using electrodes that can be embedded within earpho…

Amplitude-Independent Machine Learning for PPG through Visibility Graphs and Transfer Learning

Yuyang Miao, Harry J. Davies, Danilo P. Mandic

Photoplethysmography (PPG) refers to the measurement of variations in blood volume using light and is a feature of most wearable devices. The PPG signals provide insight into the b…

Rapid Extraction of Respiratory Waveforms from Photoplethysmography: A Deep Encoder Approach

Harry J. Davies, Danilo P. Mandic

Much of the information of breathing is contained within the photoplethysmography (PPG) signal, through changes in venous blood flow, heart rate and stroke volume. We aim to levera…

An Apparatus for the Simulation of Breathing Disorders: Physically Meaningful Generation of Surrogate Data

Harry J. Davies, Ghena Hammour, Hongjian Xiao +1

The rapidly increasing prevalence of debilitating breathing disorders, such as chronic obstructive pulmonary disease (COPD), calls for a meaningful integration of artificial intell…
