*) Rows marked by an asterisk should be taken with care as in those cases overlapping test and training sets were used. This could lead to overestimated metrics.

Runtime

The runtime is measured for the *hjdb* dataset (duration 3h19m) and then extrapolated to the duration of all datasets (total 38h51m). For measuring runtimes, we used a PC with four i5-2400 CPUs @ 3.10GHz.
