EM Estimation for the Bivariate Mixed Exponential Regression Model

In this paper, we present a new family of bivariate mixed exponential regression models for taking into account the positive correlation between the cost of claims from motor third party liability bodily injury and property damage in a versatile manner.

Read about how Arijit Das tackles the issue of balancing privacy and fairness in automated decison making while maintaing high model accuracy using the UCI Credit-Card Default dataset

A first order binomial mixed Poisson integer valued autoregressive model with serially dependent innovations
This paper is motivated by the extended Poisson INAR(1), which allows innovations to be serially dependent, develops a new family of binomial-mixed Poisson INAR(1) (BMP INAR(1)) processes by adding a mixed Poisson component to the innovations of the classical Poisson INAR(1) process.

The main purpose of this article is to present a new class of bivariate mixed Poisson regression models with varying dispersion that offers sufficient flexibility for accommodating overdispersion and accounting for the positive correlation between the number of claims from third-party liability bodily injury and property damage.

image-left Federated Learning for Privacy-Preserving Data Access
Federated learning is a pioneering privacy-preserving data technology and also a new machine learning model trained on distributed data sets. This paper discusses federated learning as a solution for privacy-preserving data access and distributed machine learning applied to distributed data sets. It also presents a privacy-preserving federated learning infrastructure.

In this work, we consider the problem of classifying sentiment of UK Twitter messages on COVID-19 using Natural Language Processing (NLP) and supervised Machine Learning techniques.

image-left A Guide for Ethical Data Science (RSS and IFoA)
The Royal Statistical Society and the Institute and Faculty of Actuaries have worked together to jointly produce an ethical framework for their members and practitioners working in the field of data science. Created with practitioners in mind, this guide seeks to provide practical support to members on ethical practice. Structured around our five core ethical themes, the guide provides examples of common ethical challenges in the field and how they could be applied.
