Temp Result Report

Result Report :

I have already train two sphere model. The first model I change hierachical softmax paramters to standard sphere. And another model is just change word vectors to standard sphere. The result shows the performance change hierachical parameters is almost 0% correct rate. So I will not write it in our result report.

Use the norm vector :

  Linear Transform :

     test :     1 correct     5 correct
                  10.25%        24.82%

     train :    
            

  Sphere Transform:

     test :       24.22%        41.01%

     train :       

Use original vector :

  Linear Transform:
     test :       26.83%        44.42%

     train : 
  Sphere Transform :
     test :       28.74%        46.73%

        11.96%   27.43%     50 classify
     Reason explain : There are some points doesn't belong to class which training data belongs to. So the
                      transform doesn't share correct transform matrix. 
                      The method we want to update is just cluster the training data, and the test 
                      the performance.
  Simple cluster by 2 class.
