grenedalf: population genetic statistics for the next generation of pool sequencing

2 code implementations20 Jun 2023 Lucas Czech, Jeffrey P. Spence, Moisés Expósito-Alonso

Pool sequencing is an efficient method for capturing genome-wide allele frequencies from multiple individuals, with broad applications such as studying adaptation in Evolve-and-Resequence experiments, monitoring of genetic diversity in wild populations, and genotype-to-phenotype mapping.

Flexible mean field variational inference using mixtures of non-overlapping exponential families

1 code implementation NeurIPS 2020 Jeffrey P. Spence

When all distributions in the model are members of exponential families and are conditionally conjugate, optimization schemes can often be derived by hand.

Variable Selection Variational Inference

A Likelihood-Free Inference Framework for Population Genetic Data using Exchangeable Neural Networks

1 code implementation NeurIPS 2018 Jeffrey Chan, Valerio Perrone, Jeffrey P. Spence, Paul A. Jenkins, Sara Mathieson, Yun S. Song

To achieve this, two inferential challenges need to be addressed: (1) population data are exchangeable, calling for methods that efficiently exploit the symmetries of the data, and (2) computing likelihoods is intractable as it requires integrating over a set of correlated, extremely high-dimensional latent variables.
