Many problems in genomics require the ability to identify relevant
features in data sets containing many more orders of magnitude than
samples. One such example is genome-wide association studies (GWAS), in
which hundreds of thousands of single nucleotide polymorphisms are
measured for orders of magnitude fewer samples.

This setup poses statistical and computational challenges, and for this
reason few approaches attempt to model non-additive effects. In my talk,
I will present methods we have developed to discover features that act
non-linearly on the outcome of interest.
