tree tdepth

[zuoshaobo]

1.why the tdepth is 5,can i chang it to other value?
every train cycle,we do choose more background images for training,when trainning result "fpr>maxfpr",we train another tree for this cycle,so every cycle may have more trees,So can we add tree's depth for every cycle when the fpr>maxfpr?
2.when the tree result not fill "fpr>maxfpr",why set the threhold value to -1337?
thank u~

1. You can set the tree depth at the beginning of the training: all trees in the cascade have to be of the same depth (due to simplicity).
2. Well, the threshold should really be set to -Inf. However, we can get the same effect with -1337 (or any other number smaller than it). https://en.wikipedia.org/wiki/Leet

Hi!
I really think changing the tree depth in different cycles is an interesting idea. Did you try it?
