<div>Dear Andreas Stolcke </div>
<div> </div>
<div>Hello. I'm ILBIN LEE who develops a speech recognizer in ETRI,
Korea.</div>
<div>While using ngram-count command of SRI LM toolkit, I encountered
the following error message.</div>
<div> </div>
<div>$ ngram-count.exe -order 3 -sort -float-counts -gt2min 1 -gt3min
1 -vocab vocab.txt -read count.txt -lm lm.txt</div>
<div>error in discount estimator for order 1</div>
<div style="font-family: ±¼¸²;">
<div>
<div style="font-family: ±¼¸²;">
<div> </div>
<div>The count file is an interpolation of two different count files.
So it has lots of fractional counts.</div>
<div>If you could suggest me some possible causes, it would help me a
lot.</div>
</div>
</div>
</div>
</div>

You cannot use Good Turing discounting with fractional counts. Try
-wbdiscount or -cdiscount or -addsmooth. <br>
<br>
The fact that you didn't get an error message also indicates that you
weren't using -float-counts, which you must when processing fractional
counts.<br>
<br>
Please also read the FAQ section on Smoothing issues before proceedings
further.<br>
