GWNBR relies on the bandwidth parameter h
. Originally, we tune h
under the D+G+P+T
setting, and applies this tunned h
for all the other feature settings in the same year. This is not right, because it is very likely that different feature settings requires different h
to achieve optimal.
Table 4 abnormal observations
In Table 4 of the TKDE draft, comparing GWNBR with NB, some results are getting worse. Specifically, comparing column 2 vs 1. Adding POI feature makes NB better, meanwhile makes GWNBR worse.
