Torchtree: flexible phylogenetic model development and inference using PyTorch

1 code implementation26 Jun 2024 Mathieu Fourment, Matthew Macaulay, Christiaan J Swanepoel, Xiang Ji, Marc A Suchard, Frederick A Matsen IV

Furthermore, we explore the use of the forward KL divergence as an optimizing criterion for variational inference, which can handle discontinuous and non-differentiable models.

19 dubious ways to compute the marginal likelihood of a phylogenetic tree topology

1 code implementation28 Nov 2018 Mathieu Fourment, Andrew F. Magee, Chris Whidden, Arman Bilge, Frederick A. Matsen IV, Vladimir N. Minin

The marginal likelihood of a model is a key quantity for assessing the evidence provided by the data in support of a model.
