Advancing ecological community analysis with MrIML 2.0: Unravelling taxa associations through interpretable machine learning
Year: 2024
Type: preprint
Abstract: Understanding the assembly of ecological communities is a core goal in ecology. Despite advancements in statistical models, disentangling the influences of biotic and abiotic constraints on communities remains challenging due to data complexity. We introduce the MrIML 2.0 R package (multi-response interpretable machine learning) which employs machine learning to approximate graphical network models (GGNs), revealing complex relationships in community structure, including asymmetric co-occurrence associations where one species influences another but not vice versa. Using the Tidymodels R architecture, we empower users to build models across algorithms and interpret them using interpretable machine learning (IML) approaches. Our method captures known interactions in simulated data and improves upon commonly used models by quantifying marginal relationships that capture non-linear biotic relationships and complex predictor interactions. We validate our approach on a range of datasets, highlighting the method’s efficacy in providing high-resolution insights into community dynamics and generating new hypotheses for ecological research.
