<div>Hello,</div>
<div> </div>
<div>I have a question about related to SRILM implmentation. I
found that gtnmin gtnmax affects some smoothing methods
results ( absolute, wb, kn). According to its documentation (<a
moz-do-not-send="true"
href="http://www.speech.sri.com/projects/srilm/manpages/ngram-discount.7.html">http://www.speech.sri.com/projects/srilm/manpages/ngram-discount.7.html</a>) ,
gtnmin or gtnmax should affect GT smoothing method only. Can
any one explain this strange behavior for me?</div>
</div>

gtNmax affects only GT discounting.<br>
gtNminx affects all methods.<br>
<br>
This is documented in the ngram-count man page:<br>
<blockquote type="cite"> -gtnmin count<br>
where n is 1, 2, 3, 4, 5, 6, 7, 8, or 9. Set the
minimal count of N-grams of order n that will be included in the
LM.<br>
All N-grams with frequency lower than that will
effectively be discounted to 0. If n is omitted the parameter
for N-<br>
grams of order > 9 is set.<br>
NOTE: This option affects not only the default
Good-Turing discounting but the alternative discounting methods
described<br>
below as well.<br>

(see the NOTE).<br>
