Role of the site of synaptic competition and the balance of learning forces for Hebbian encoding of probabilistic Markov sequences

open access: yesFrontiers in Computational Neuroscience, 2015
The majority of distinct sensory and motor events occur as temporally ordered sequences with rich probabilistic structure. Sequences can be characterized by the probability of transitioning from the current state to upcoming states (forward probability),

Hyper Normalisation and Conditioning for Discrete Probability Distributions [PDF]

open access: yesLogical Methods in Computer Science, 2017
Normalisation in probability theory turns a subdistribution into a proper distribution. It is a partial operation, since it is undefined for the zero subdistribution. This partiality makes it hard to reason equationally about normalisation. A novel description of normalisation is given as a mathematically well-behaved total function. The output of this

Gaussian Covariance Faithful Markov Trees

open access: yesJournal of Probability and Statistics, 2011
Graphical models are useful for characterizing conditional and marginal independence structures in high-dimensional distributions. An important class of graphical models is covariance graph models, where the nodes of a graph represent different ...
