Protein function prediction is an active area of research in bioinformatics. And
yet, transfer of annotation on the basis of sequence or structural similarity
remains widely used in practice. Most of the machine learning methods applied
to this problem reduce it to a collection of binary classification problems:
whether a protein performs a particular function, sometimes with a
post-processing step to combine the binary outputs. I will present the GOstruct
method that directly predicts the Gene Ontology terms associated with a protein
by modeling the hierarchical structure of the Gene Ontology in the framework of
kernel methods for structured-output spaces. Empirical results show improved
performance over several algorithms that were
recently benchmarked on the Mousefunc dataset.
