Predicting the Performance of a Computing System with Deep Networks

no code implementations27 Feb 2023 Mehmet Cengiz, Matthew Forshaw, Amir Atapour-Abarghouei, Andrew Stephen McGough

Existing approaches to understanding the performance of hardware largely focus around benchmarking -- leveraging standardised workloads which seek to be representative of an end-user's needs.

Siamese Neural Networks for Skin Cancer Classification and New Class Detection using Clinical and Dermoscopic Image Datasets

no code implementations12 Dec 2022 Michael Luke Battle, Amir Atapour-Abarghouei, Andrew Stephen McGough

Instead, we evaluate Siamese Neural Networks (SNNs), which not only allows us to classify images of skin lesions, but also allow us to identify those images which are different from the trained classes - allowing us to determine that an image is not an example of our training classes.

Analysis of Reinforcement Learning for determining task replication in workflows

no code implementations14 Sep 2022 Andrew Stephen McGough, Matthew Forshaw

We show, through simulation, that we can save 34% of the energy consumption using RL compared to a fixed number of replicas with only a 4% decrease in workflows achieving a pre-defined overhead bound.

Long-term Reproducibility for Neural Architecture Search

1 code implementation11 Jul 2022 David Towers, Matthew Forshaw, Amir Atapour-Abarghouei, Andrew Stephen McGough

It is a sad reflection of modern academia that code is often ignored after publication -- there is no academic 'kudos' for bug fixes / maintenance.

SpiderNet: Hybrid Differentiable-Evolutionary Architecture Search via Train-Free Metrics

1 code implementation20 Apr 2022 Rob Geada, Andrew Stephen McGough

Neural Architecture Search (NAS) algorithms are intended to remove the burden of manual neural network design, and have shown to be capable of designing excellent models for a variety of well-known problems.

Application of deep learning to camera trap data for ecologists in planning / engineering -- Can captivity imagery train a model which generalises to the wild?

no code implementations24 Nov 2021 Ryan Curry, Cameron Trotter, Andrew Stephen McGough

This is the first research which attempts to generate a training set based on captivity data and the first to explore the development of such models in the context of ecologists in planning/engineering.

A Kings Ransom for Encryption: Ransomware Classification using Augmented One-Shot Learning and Bayesian Approximation

1 code implementation19 Aug 2019 Amir Atapour-Abarghouei, Stephen Bonner, Andrew Stephen McGough

In this paper, we investigate the possibility of classifying the ransomware a system is infected with simply based on a screenshot of the splash screen or the ransom note captured using a consumer camera commonly found in any modern mobile device.

TMIXT: A process flow for Transcribing MIXed handwritten and machine-printed Text

1 code implementation28 Apr 2019 Fady Medhat, Mahnaz Mohammadi, Sardar Jaf, Chris G. Willcocks, Toby P. Breckon, Peter Matthews, Andrew Stephen McGough, Georgios Theodoropoulos, Boguslaw Obara

In this work, we present a generic process flow for text recognition in scanned documents containing mixed handwritten and machine-printed text without the need to classify text in advance.

Predicting the Computational Cost of Deep Learning Models

1 code implementation28 Nov 2018 Daniel Justus, John Brennan, Stephen Bonner, Andrew Stephen McGough

But, also, it has the ability to predict execution times for scenarios unseen in the training data.

Exploring the Semantic Content of Unsupervised Graph Embeddings: An Empirical Study

2 code implementations19 Jun 2018 Stephen Bonner, Ibad Kureshi, John Brennan, Georgios Theodoropoulos, Andrew Stephen McGough, Boguslaw Obara

To explore this, we present extensive experimental evaluation from five state-of-the-art unsupervised graph embedding techniques, across a range of empirical graph datasets, measuring a selection of topological features.
