Changepoint detection in non-exchangeable data
Karl L. Hallgren, Nicholas A. Heard, Niall M. Adams
Changepoint models typically assume the data within each segment are independent and identically distributed conditional on some parameters which change across segments. This const…
A Parameter Estimation Method for Multivariate Aggregated Hawkes Processes
Leigh Shlomovich, Edward A. K. Cohen, Niall Adams
It is often assumed that events cannot occur simultaneously when modelling data with point processes. This raises a problem as real-world data often contains synchronous observatio…
Prospective Artificial Intelligence Approaches for Active Cyber Defence
Neil Dhir, Henrique Hoeltgebaum, Niall Adams +3
Cybercriminals are rapidly developing new malicious tools that leverage artificial intelligence (AI) to enable new classes of adaptive and stealthy attacks. New defensive methods n…
Testing for complete spatial randomness on three dimensional bounded convex shapes
Scott Ward, Edward A. K. Cohen, Niall Adams
There is currently a gap in theory for point patterns that lie on the surface of objects, with researchers focusing on patterns that lie in a Euclidean space, typically planar and…
A Monte Carlo EM Algorithm for the Parameter Estimation of Aggregated Hawkes Processes
Leigh Shlomovich, Edward Cohen, Niall Adams +1
A key difficulty that arises from real event data is imprecision in the recording of event time-stamps. In many cases, retaining event times with a high precision is expensive due…
On Adaptive Estimation for Dynamic Bernoulli Bandits
Xue Lu, Niall Adams, Nikolas Kantas
The multi-armed bandit (MAB) problem is a classic example of the exploration-exploitation dilemma. It is concerned with maximising the total rewards for a gambler by sequentially p…
