You are now viewing the homepage of PIT Bioinformatics Group. We are a bioinformatics research group, established in 2005, in the Institute of Mathematics of the Eötvös Loránd University, Budapest, Hungary. We solve problems arising in life sciences by mathematical and informatical means.
During the past years we have developed several online tools for bioinformatics research. These useful pieces of software, which run on our high-performance server computers, are available on the online tools page or in the sidebar in the right.

Near Perfect Protein Multi-Label Classification with Deep Neural Networks
Our new paper "Near Perfect Protein Multi-Label Classification with Deep Neural Networks" was published on arxiv.org on 30 Mar 2017.
Artificial neural networks (ANNs) have gained a well-deserved popularity among machine learning tools upon their recent successful applications in image- and sound processing and classification problems. Here we present two new ANNs with multi-label classification ability, showing impressive accuracy when classifying protein sequences into 698 UniProt families (AUC=99.99%) and 983 Gene Ontology classes (AUC=99.45%).
