Dear Adam, When I use qnstrn to get TRAP feature, it prints "(QN_InFtrStream_RandWindow.ftr1_file): WARNING - Segment 2292 has only 90 frames, which is too...
Until now, PLP_MLP feature increased the performance accuracy of Mandarin CTS in our experiment. Now we want to try TRAPs into our system. If I use qnstrn to...
... I haven't run Mandarin CTS myself, so maybe somebody else on the list can answer in more detail, but for English, high 60s for frame ACCURACY (not error)...
From your message, I assume you're using the MLP outputs as features to a GMM (so-called "tandem") rather than using the posteriors directly (so-called...
There is another problem: When we use MLP feature on Mandarin CTS, the Frame Error Rate of training data was up to 60% after NN training. Does this a little ...
Dear Adam, I am so sorry that I did not explain the problem clearly. Actually, we found that MLP has the much larger dynamic range than PLP has (In the log...
... I'm not sure I understand. If you're using softmax as the output layer of the MLP, then all the values should be between 0.0 and 1.0. If you're not using...
When I use MLP as my HMM features, the POSITIVE posteriori probabilities always occurred. The POSITIVE posteriori probabilities will break the decoding rule...
... Does your CV set start at segment 4802 by any chance? If so, that's what causes the message -- when the CV run starts, it seeks to the start of the CV run....
... If you're computing normalization online and then try to seek to the middle of a feature stream, it has to back up to the start and read all the...
When I run qnstrn with online CMS, it prints "./qnstrn(QN_InFtrStream_OnlNorm.ftr1_file): WARNING - slow seek to mid-seg (seg/fr 4802/81) with online norm" ...
When I executed ./labels2pfile, it printed "can't find package Dpwe_Utilfns while executing "package require Dpwe_Utilfns" (file "./labels2pfile" line 16)" Did...
Hi, This week, we are planning to make noway version 2.9.3 available at ftp://ftp.icsi.berkeley.edu/pub/real/davidj/. The only change compared to version 2.9.2...

Hi all, IN SHORT: mlp_bunch_size > 256 does not train properly I have been using for years qnstrn/qnmultitrn with a bunch size of 256, which trains much faster...
Hi Eric, ... Arlo already proposed a good solution. I cooperate with Brno guys on the new shiny Bottle-Neck features :) (hopefully more in ICASSP'08 paper) and...
... Yes, that's the idea in principle. In practice, I actually somewhat over-sample the more frequent classes for performance reasons. ... I randomly sample...
