Topological Data Analysis for Anomaly Detection in Host-Based Logs

no code implementations25 Apr 2022 Thomas Davies

Topological Data Analysis (TDA) gives practioners the ability to analyse the global structure of cybersecurity data.

A Review of Topological Data Analysis for Cybersecurity

no code implementations16 Feb 2022 Thomas Davies

In cybersecurity it is often the case that malicious or anomalous activity can only be detected by combining many weak indicators of compromise, any one of which may not raise suspicion when taken alone.

Topological Vanilla Transfer Learning

no code implementations29 Sep 2021 Nicholas George Bishop, Lau Truong Nguyen, Hieu Trung Thai, Thomas Davies, Long Tran-Thanh

In this paper we investigate the connection of topological similarity between source and target tasks with the efficiency of vanilla transfer learning (i. e., transfer learning without retraining) between them.

Hypothesis classes with a unique persistence diagram are NOT nonuniformly learnable

no code implementations NeurIPS Workshop TDA_and_Beyond 2020 Nicholas George Bishop, Thomas Davies, Long Tran-Thanh

The implicit role of a topological term in a loss function is to restrict the class of functions in which we are learning (the hypothesis class) to those with a specific topology.

On the Effectiveness of Weight-Encoded Neural Implicit 3D Shapes

3 code implementations17 Sep 2020 Thomas Davies, Derek Nowrouzezahrai, Alec Jacobson

Many prior works have focused on _latent-encoded_ neural implicits, where a latent vector encoding of a specific shape is also fed as input.

UV-Net: Learning from Boundary Representations

1 code implementation CVPR 2021 Pradeep Kumar Jayaraman, Aditya Sanghi, Joseph G. Lambourne, Karl D. D. Willis, Thomas Davies, Hooman Shayani, Nigel Morris

We introduce UV-Net, a novel neural network architecture and representation designed to operate directly on Boundary representation (B-rep) data from 3D CAD models.

Fuzzy c-Means Clustering for Persistence Diagrams

1 code implementation4 Jun 2020 Thomas Davies, Jack Aspinall, Bryan Wilder, Long Tran-Thanh

We end with experiments on two datasets that utilise both the topological and fuzzy nature of our algorithm: pre-trained model selection in machine learning and lattices structures from materials science.
