20th - 23rd February 2023
Due to the COVID-19 outbreak, this course will be held online
In recent years, deep learning techniques are increasingly being used in evolutionary studies due to their flexible and data-hungry nature, suitable to analyze large and complex genomic datasets.
This course will focus on using deep learning, specifically Convolutional Neural Networks (CNN), to extract information from genetic data for population genomics and phylogeography
inference. The theoretical background for simulating genetic data and developing deep learning architectures will be covered and followed by practical examples, in modules structured over five
days. On the first day, the participants will learn how to conceive and simulate genetic data under competing demographic scenarios. Day 2 will cover deep learning background and simple practical
examples to understand how a CNN works. In Day 3, deep learning will be used to compare the demographic scenarios conceived in Day 1. Day 4 will be dedicated to the simulation of genomic regions
with selective sweeps and using CNN to detect such regions on real genomes. The course is structured to include lectures with discussions of key concepts and practical hands-on sessions,
contextualised with research study cases.
The course is aimed at graduate students, researchers and professionals interested in genetics, evolution and deep learning, interested in developing applications to test explicit demographic hypotheses and search for selective sweeps. The course will include both general concepts of genetic data simulations and deep learning but will also include more advanced discussion on advanced details on their internal machinery. The examples discussed during the course will span datasets for both model organisms, for which whole genomes are available, and non-model organisms with less available information.
