Functional connectivity (FC) of blood-oxygen-level-dependent (BOLD) fMRI time series can be estimated using methods that differ in sensitivity to the temporal order of time points (static vs. dynamic) and the number of regions considered in estimating a single edge (bivariate vs. multivariate). Prev ...

Integrating motivational signals with cognition is critical for goal-directed activities. The mechanisms that link neural changes with motivated working memory continue to be understood. Here, we tested how externally cued and non-cued (internally represented) reward and loss impact spatial working ...

How can we represent data on a computer and use it to learn to perform
useful tasks? This lecture reviews some simple classification and
regression rules, discusses under- and over-fitting and emphasises the
utility of defining objective functions for learning. There is also a
short overview of Baye ...

The Gaussian process (GP) is a popular way to specify dependencies between random variables in a probabilistic model. In the Bayesian framework the covariance structure can be specified using unknown hyperparameters. Integrating over these hyperparameters considers different possible explanations fo ...

We consider the design of Markov chain Monte Carlo (MCMC) methods for large-scale, distributed,
heterogeneous compute facilities, with a focus on synthesising sample sets across multiple runs
performed in parallel. While theory suggests that many independent Markov chains may be run
and their sample ...

The development of drug dependence relies heavily on an aberrant learning history. Initially, the experience of the drug itself is linked with environmental cues through a process of Pavlovian conditioning. The unconditioned drug stimulus becomes associated with conditioned stimuli that can then com ...

This paper evaluates the use of prior knowledge to limit or bias the choices of a classifer during otherwise unsupervised training and classifcation. Focusing on effects in the uncertainty of the model's decisions, we quantify the contributions of the knowledge source
as a reduction in the conditio ...
