Understanding Social Immunity in Ants: A Markovian Approach to Collective Cleaning Strategies

no code implementations8 Feb 2024 Isabella Bueno, Gabriel R. Palma, Idemauro A. R. Lara, Rafael A. Moral, Italo Delalibera Jr, Wesley A. C. Godoy

We investigate how worker interactions and previous behaviors influence the evolution of social immunity strategies in response to the presence of pathogens and vulnerable colony members.

Forecasting insect abundance using time series embedding and machine learning

no code implementations22 Dec 2023 Gabriel R. Palma, Rodrigo F. Mello, Wesley A. C. Godoy, Eduardo Engel, Douglas Lau, Charles Markham, Rafael A. Moral

We pre-processed the data using our newly proposed approach and more straightforward approaches commonly used to train machine learning algorithms in time series problems.

Going beyond richness: Modelling the BEF relationship using species identity, evenness, richness and species interactions via the DImodels R package

no code implementations9 Dec 2022 Rafael A. Moral, Rishabh Vishwakarma, John Connolly, Laura Byrne, Catherine Hurley, John A. Finn, Caroline Brophy

It is common in BEF studies to model an ecosystem function as a function of richness; while this can uncover trends in the BEF relationship, by definition, species diversity is much broader than richness alone, and important patterns in the BEF relationship may remain hidden.

Profiling Television Watching Behaviour Using Bayesian Hierarchical Joint Models for Time-to-Event and Count Data

1 code implementation6 Sep 2022 Rafael A. Moral, Zhi Chen, Shuai Zhang, Sally McClean, Gabriel R. Palma, Brahim Allan, Ian Kegel

The model drastically reduces the dimensionality of the data from thousands of observations per customer to 11 customer-level parameter estimates and random effects.

Bayesian Additive Regression Trees with Model Trees

1 code implementation12 Jun 2020 Estevão B. Prado, Rafael A. Moral, Andrew C. Parnell

BART assumes regularisation priors on a set of trees that work as weak learners and is very flexible for predicting in the presence of non-linearity and high-order interactions.
