[Kaldi-developers] how to use kaldi to do linear regression

[雪莲 <amy...@16...>]

 Dear sir or miss :
       Sorry to bother you!
       I want to know whether kaldi could do linear regression instead of softmax classification? I am a postgraduate student in China, I need to do acoustic-articulatory inversion, I've modified the code in pre-traindbn.sh to get a pretrained dbn, now there left is how to do linear regression on this dbn, I'm not good at programming languages and kaldi toolkit is the most familiar toolkit for me, so I've leaned almost all my work on kaldi.
      I am in a rush to find out how to do it, I really hope you could help me with this , if kaldi can perform linear regression, please tell me which tool I should use. Thank you very much!!!
    I am really grateful for your help!
