Dear TDT-ers,

Consider the situation where we opt to use Nt (the number of positive topic
examples) to be 6 for topic tracking. Then the TDT description says that we
must use the last 6 positive examples only.
That is from positive example 11 through 16 (which is the maximum positive
examples given). Let us assume that the 11th positive example is item number
1000.

1) can we use the negative examples in items 1 through 999 during training?

2) can we extract statistics such as IDF from all items in 1 through 999
during training?

thanks much,

Padmini
