2011-9-4 · Overall the RLS-Kron and RLS-avg methods have comparable AUC scores. However the RLS-Kron has a better AUPR when using the GIP kernel and a worse AUPR when using the chemical and genomic kernels. We believe that this problem is due to the poor quality of the chemical similarity kernel to which the RLS-Kron method is more sensitive.
