oops, i forgot. In phrase-based decoding, the 1st hypothesis (in stack
0) have states created by the method
StatefulFeatureFunction::EmptyHypothesisState()
that you have to override for every stateful ff. Put code to rest your
state info here

Hi Hieu,
Thank you for your reply. I tried both of these approaches.
In first case, I get an exception at NOT_FOUND. When I try to print
the words range array, the minimum is always "wordsRange: [0..0]”.
In second case, "cur_hypo.GetWordsBitmap().GetNumWordsCovered() == 0”
is never true as the minimum I get is equal to 1.
As, InitializeForInput() cannot be useful in my current situation, is
there any other way to know when I start processing a new sentence?
Thank you and regards,
Jasneet

i get ya. You can do
EvaluateWhenApplied(Hypothesis cur_hypo, FFState,
ScoreComponenetCollection) {
If (cur_hypo.GetCurrSourceWordsRange() == NOT_FOUND) then {
LMState = CoarseLM->BeginSentenceState()
}
}
or
EvaluateWhenApplied(Hypothesis cur_hypo, FFState,
ScoreComponenetCollection) {
If (cur_hypo.GetWordsBitmap().GetNumWordsCovered() == 0) then {
LMState = CoarseLM->BeginSentenceState()
}
}
Each FF can also override
InitializeForInput()
This might not be suitable for you on this occasion, but it's worth
bearing in mind

Hi Hieu,
Thanks for replying. For example:
EvaluateWhenApplied(Hypothesis, FFState, ScoreComponenetCollection) {
If (processing a new source sentence), then {
LMState = CoarseLM->BeginSentenceState()
}
}
Here, I am trying to check if I am processing a new source sentence,
so I should reset my language model states that I calling from my
feature function.
Does this give an idea of what I am trying to do?
Regards,

Hi Everyone,
I have added a feature function in Moses. Is it possible to
know through the Hypothesis parameter in “EvaluateWhenApplied”
function that I am now processing the first state in a new
source sentence. I would like to reset certain states whenever
we start translating a new source sentence.
Thank you for the help.
Regards,
Jasneet
