Actually, is there any good reason to have this option not enabled by
default?

This particular error does not indicate singletons, there is a
different error message for that.
Sometimes discounts are just weird. Kneser-Ney smoohting requires them
to be larger than 0, I do not really know though how negative
discounts come to be.

More specifically, it's a sign that your data might have to be
de-duplicated. The error occurs when there are no singleton n-grams
of a certain order.

Hi,
That's what --discount_fallback is for.
Best,

hi all
does anyone know how to fix this error from lmplz:
terminate called after throwing an instance of
'lm::builder::BadDiscountException'
what(): ERROR: 4-gram discount out of range for adjusted
count 3:
-0.446424 <tel:0.446424>
The command I was running is
.../lmplz --text .../Ubuntu.truecased.3 --order 5 --arpa
.../Ubuntu.lm.3 --prune 0 0 1 -T .../lm -S 20%
I guess there's not enough data to create a 5-gram
