In January 2018 Roberta accepted to lead as a Senior Manager the new Credit Risk Data Science team at NewDay, the largest credit card issuer in the UK.
Roberta studied Bayesian inference and mathematical biology at the University of Glasgow but then decided to leave the academia and become a data scientist. She built her analytical and modelling skills at Ocado Technology for three years and then moved to ICLP Loyalty in September 2016. In 2017 she joined Camelot UK and embrace the challenge of building from the ground up the Big Data capabilities and the Data Science team.
She specialise in mathematical modelling, machine learning and Bayesian Statistics.

Gaussian Processes for Big Data problems - Intermediate
Featuring Roberta Cretella
Gaussian Processes (GPs) underpin a range of algorithms for regression, classification and unsupervised learning. GPs are mathematically equivalent to many well known models, including Bayesian linear models, spline models, large neural networks (under suitable conditions), and are closely...gaussian-process big-data data infiniteconf
