Changepoint detection in the presence of outliers
P Fearnhead, G Rigaill - Journal of the American Statistical …, 2019 - Taylor & Francis
Many traditional methods for identifying changepoints can struggle in the presence of
outliers, or when the noise is heavy-tailed. Often they will infer additional changepoints to fit …

[HTML][HTML] Consistent selection of the number of change-points via sample-splitting
In multiple change-point analysis, one of the major challenges is to estimate the number of
change-points. Most existing approaches attempt to minimize a Schwarz information …

Most recent changepoint detection in panel data
L Bardwell, P Fearnhead, IA Eckley, S Smith… - Technometrics, 2019 - Taylor & Francis
Detecting recent changepoints in time-series can be important for short-term prediction, as
we can then base predictions just on the data since the changepoint. In many applications …

Bayesian sensor fault detection in a Markov jump system
In this paper, the fault detection of a latent fault in a sensor for a Markov jump system is
studied. It is equivalent to detecting a change point in a coefficient vector of a measurement …
