Impact of different starting trees on DACTAL-based boosting with MP-EST. We show the average FN rates of the best trees, with respect to the quartet support, after five iterations of DACTAL-based boosting using MP-EST and using the starting trees estimated by MRP and MP-EST on the simulated mammalian datasets with varying sequence length (200 genes, moderate amount of ILS). We ran MP-EST on the subsets produced by the DACTAL-based decomposition with maximum subset size 15 using different starting trees. MP-EST(MRP,dactal,15,q) refers to the results obtained by using the MRP-estimated starting tree, while MP-EST(MP-EST,dactal,15,q) refers to the results obtained by using the starting tree estimated by MP-EST. We also show the FN rates of concatenation and the starting trees estimated by MP-EST and MRP.
