Abstract : Recent methods for demographic history inference have achieved good results, circumventing the complexity of raw genomic data by summarizing them into handcrafted features called summary statistics [1, 3]. We developed a new approach based on deep learning that takes as input the variant sites found within a sample of individuals from the same population, and infers demographic descriptor values without relying on these predefined summary statistics. By letting our model choose how to handle raw data and learn its own way to embed them, we were able to outperform a method frequently used in population genetics for the inference of three out of seven demographic descriptor values of a scenario with a bottleneck and two expansions. This is still preliminary work and we are hopeful that future developments would allow us to tackle a broader range of demographic scenarios and outperform previous methods by developing more flexible artificial neural network architectures.
