Aetiology and epidemiology of surgical vitreoretinal presentations in an Australian paediatric population: A seven‐year retrospective study

Clinical &Experimental Ophthalmology, Volume 52, Issue 8, Page 861-869, November 2024.
Abstract Background Paediatric vitreoretinal pathology is distinct from adult cases in both presentation and surgical planning. Here we aim to report the aetiology and epidemiology in children 0–18 years requiring vitreoretinal surgery at a major tertiary paediatric hospital in Queensland, Australia.

Tutorial on Implied Posterior Probability for SVMs [PDF]

arXiv, 2019
Implied posterior probability of a given model (say, Support Vector Machines (SVM)) at a point $\bf{x}$ is an estimate of the class posterior probability pertaining to the class of functions of the model applied to a given dataset. It can be regarded as a score (or estimate) for the true posterior probability, which can then be calibrated/mapped onto ...

Topical dorzolamide for macular holes: A randomised, double‐blind, placebo‐controlled trial

Clinical &Experimental Ophthalmology, Volume 52, Issue 8, Page 870-879, November 2024.
Abstract Background To assess topical dorzolamide as medical therapy for idiopathic full‐thickness macular holes (FTMHs). Methods Randomised, double‐blinded, placebo‐controlled, single‐centre clinical trial involving 32 patients with idiopathic small FTMHs (<400 μm).

Query Efficient Posterior Estimation in Scientific Experiments via Bayesian Active Learning [PDF]

, 2017
A common problem in disciplines of applied Statistics research such as Astrostatistics is of estimating the posterior distribution of relevant parameters. Typically, the likelihoods for such models are computed via expensive experiments such as cosmological simulations of the universe. An urgent challenge in these research domains is to develop methods

Subfoveal retinal detachment associated with dome-shaped macula in a 6 year-old child: Comparison with other case reports and systematic review of the literature regarding dome-shaped macula in children

American Journal of Ophthalmology Case Reports, 2020
Purpose: To describe the case of an asymptomatic 6-year-old girl, who was found to have bilateral dome-shaped macula, associated with left serous macular detachment and left optic disc pit, and no evidence of posterior staphyloma in either eye, and to ...

A Random Weighting Approach for Posterior Distributions [PDF]

arXiv, 2012
In Bayesian theory, calculating a posterior probability distribution is highly important but usually difficult. Therefore, some methods have been put forward to deal with such problem, among which, the most popular one is the asymptotic expansions for posterior distributions.

Optimal Posteriors for Chi-squared Divergence based PAC-Bayesian Bounds and Comparison with KL-divergence based Optimal Posteriors and Cross-Validation Procedure [PDF]

arXiv, 2020
We investigate optimal posteriors for recently introduced \cite{begin2016pac} chi-squared divergence based PAC-Bayesian bounds in terms of nature of their distribution, scalability of computations, and test set performance. For a finite classifier set, we deduce bounds for three distance functions: KL-divergence, linear and squared distances.
