Last week:

          1.When the first reverberation is only considered ,that is N=1,the error rate is obtained.  The result is worse. 
          2.apply the Lasso algorithm to Fbank.  

This week:

          1.reduce training sets,compute the mean value of the every franme alpha, and the error rate is obtained.
          2.design and realize dynamic Lasso.
