Deep learning for omics data : Application to phenotype prediction based in gene expression data
In the first part of the talk, I will make a quick state of the art of the problems in “omics” data analysis in which deep learning has been used successfully. Then I will present our work on the prediction of phenotype based on gene expression data with a deep neural network. In this task, we focus on two issues: the learning with a small training set and the interpretation of the network. For the small training set problem, we propose methods based on transfer learning and semi-supervised learning. For interpretation, we backpropagate the predictions through the network in order to identify relevant genes and neurons that we associate them to biological knowledge.
