Statistical Inference for Modulation Index in Phase-Amplitude Coupling
Marco Antonio Pinto-Orellana, Hernando Ombao, Beth Lopour
Phase-amplitude coupling is a phenomenon observed in several neurological processes, where the phase of one signal modulates the amplitude of another signal with a distinct frequen…
Stylized Projected GAN: A Novel Architecture for Fast and Realistic Image Generation
Md Nurul Muttakin, Malik Shahid Sultan, Robert Hoehndorf +1
Generative Adversarial Networks are used for generating the data using a generator and a discriminator, GANs usually produce high-quality images, but training GANs in an adversaria…
Topological Data Analysis for Directed Dependence Networks of Multivariate Time Series Data
Anass B. El-Yaagoubi, Hernando Ombao
Topological data analysis (TDA) approaches are becoming increasingly popular for studying the dependence patterns in multivariate time series data. In particular, various dependenc…
An MCMC Approach to Bayesian Image Analysis in Fourier Space
Konstantinos Bakas, John Kornak, Hernando Ombao
Bayesian methods are commonly applied to solve image analysis problems such as noise-reduction, feature enhancement and object detection. A primary limitation of these approaches i…
Bayesian Nonparametric Multivariate Mixture of Autoregressive Processes: With Application to Brain Signals
Guillermo Granados-Garcia, Raquel Prado, Hernando Ombao
One of the goals of neuroscience is to study interactions between different brain regions during rest and while performing specific cognitive tasks. The Multivariate Bayesian Autor…
Dynamic cross-scale wavelet coherence
Haibo Wu, Marina I. Knight, Hernando Ombao
This paper develops a novel statistical approach that allows for the {\em first time} the {\em cross}-oscillatory characterisation of temporally localised interactions between chan…
Measuring Information Transfer Between Nodes in a Brain Network through Spectral Transfer Entropy
Paolo Victor Redondo, Raphael Huser, Hernando Ombao
Brain connectivity characterizes interactions between different regions of a brain network during resting-state or performance of a cognitive task. In studying brain signals such a…
An Improved Unbiased Particle Filter
Ajay Jasra, Mohamed Maama, Hernando Ombao
In this paper we consider the filtering of partially observed multi-dimensional diffusion processes that are observed regularly at discrete times. We assume that, for numerical rea…
Antithetic Multilevel Particle Filters
Ajay Jasra, Mohamed Maama, Hernando Ombao
In this paper we consider the filtering of partially observed multi-dimensional diffusion processes that are observed regularly at discrete times. This is a challenging problem whi…
