The two-point correlation function covariance with fewer mocks
We present FITCOV an approach for accurate estimation of the covariance of two-point correlation functions that requires fewer mocks than the standard mock-based covariance. This can be achieved by dividing a set of mocks into jackknife regions and fitting ...
Oxford2023Parametric Estimation For Functional Autoregressive Processes On The Sphere
The aim of this paper is to define a nonlinear least squares estimator for the spectral parameters of a spherical autoregressive process of order 1 in a parametric setting. Furthermore, we investigate on its asymptotic properties, such as weak consistency ...
2022PoGaIN: Poisson-Gaussian Image Noise Modeling From Paired Samples
Sabine Süsstrunk, Majed El Helou, Kaan Okumus
Image noise can often be accurately fitted to a Poisson-Gaussian distribution. However, estimating the distribution parameters from a noisy image only is a challenging task. Here, we study the case when paired noisy and noise-free samples are accessible. N ...
2022Predicting learners' effortful behaviour in adaptive assessment using multimodal data
Kshitij Sharma, Jennifer Kaitlyn Olsen
Many factors influence learners' performance on an activity beyond the knowledge required. Learners' on-task effort has been acknowledged for strongly relating to their educational outcomes, reflecting how actively they are engaged in that activity. Howeve ...
ASSOC COMPUTING MACHINERY2020Functional Peaks-Over-Threshold Analysis for Complex Extreme Events
Most current risk assessment for complex extreme events relies on catalogues of similar events, either historical or generated artificially. In the latter, no existing methods produce completely new events with mathematically justified extrapolation above ...
