Radial Spike and Slab Bayesian Neural Networks for Sparse Data in Ransomware Attacks
Jurijs Nazarovs, Jack W. Stokes, Melissa Turcotte +2
Ransomware attacks are increasing at an alarming rate, leading to large financial losses, unrecoverable encrypted data, data leakage, and privacy concerns. The prompt detection of…
Changepoint detection on a graph of time series
Karl L. Hallgren, Nicholas A. Heard, Melissa J. M. Turcotte
When analysing multiple time series that may be subject to changepoints, it is sometimes possible to specify a priori, by means of a graph, which pairs of time series are likely to…
Graph link prediction in computer networks using Poisson matrix factorisation
Francesco Sanna Passino, Melissa J. M. Turcotte, Nicholas A. Heard
Graph link prediction is an important task in cyber-security: relationships between entities within a computer network, such as users interacting with computers, or system librarie…
Unified Host and Network Data Set
Melissa J. M. Turcotte, Alexander D. Kent, Curtis Hash
The lack of data sets derived from operational enterprise networks continues to be a critical deficiency in the cyber security research community. Unfortunately, releasing viable d…
Detecting periodic subsequences in cyber security data
Matthew Price-Williams, Nick Heard, Melissa Turcotte
Statistical approaches to cyber-security involve building realistic probability models of computer network data. In a data pre-processing phase, separating automated events from th…
Adaptive sequential Monte Carlo for multiple changepoint analysis
Melissa J. M. Turcotte, Nicholas A. Heard
Process monitoring and control requires detection of structural changes in a data stream in real time. This article introduces an efficient sequential Monte Carlo algorithm designe…
Monte Carlo convergence of rival samplers
Nicholas Heard, Melissa Turcotte
It is often necessary to make sampling-based statistical inference about many probability distributions in parallel. Given a finite computational resource, this article addresses h…
