A Multivariate Point Process Model for Simultaneously Recorded Neural Spike Trains
Reza Ramezan, Meixi Chen, Martin Lysy +1
The current state-of-the-art in neurophysiological data collection allows for simultaneous recording of tens to hundreds of neurons, for which point processes are an appropriate st…
Mixture Models: Building a Parameter Space
Vahed Maroufy, Paul Marriott
Despite the flexibility and popularity of mixture models, their associated parameter spaces are often difficult to represent due to fundamental identification problems. This paper…
Generalizing the Frailty Assumptions in Survival Analysis
Vahed Maroufy, Paul Marriott
This paper studies Cox's regression hazard model with an unobservable random frailty where no specific distribution is postulated for the frailty variable, and the marginal lifetim…
Local and global robustness in conjugate Bayesian analysis
Vahed Maroufy, Paul Marriott
This paper studies the influence of perturbations of conjugate priors in Bayesian inference. A perturbed prior is defined inside a larger family, local mixture models, and the effe…
Detection of Phase Shift Events
William Marshall, Paul Marriott
We consider the problem of change-point estimation of the instantaneous phase of an observed time series. Such change points, or phase shifts, can be markers of information transfe…
Variational Bayes inference and Dirichlet process priors
Hui Zhao, Paul Marriott
This paper shows how the variational Bayes method provides a computational efficient technique in the context of hierarchical modelling using Dirichlet process priors, in particula…
