Reproduce DSSM Baseline (Chao Xing)

2016-04-28 : Given a talk to text team for some recently paper. 
              Knowledge Base Completion via Search-Based Question Answering : pdf
              Open Domain Question Answering via Semantic Enrichment  : pdf
              A Neural Conversational Model : pdf
              And given a tiny results for CNN-DSSM in huilan's weekly report.
2016-04-27 : Code Multi-layer CNN, suffered from memory error in GPU in tensorflow. 
              So I run such test on CPU, should slow.
2016-04-26 : Code done tricky & analysis such tricky.
2016-04-25 : Find a tricky to improve accuracy given by Tianyi. 
            : Code for this tricky.
2016-04-23 : Set a series of experiment set. 
              1. Try deep CNN-DSSM, current model just follow proposed model contain one convolution layer, need to be a tuneable parameter.
              2. Test whether mixture data effective to current model and deep CDSSM.
              3. Code Recurrent CNN-DSSM (new approach.)
2016-04-22 : Find a problem : Use labs' gpu machine 970 iteration per time is 1537 second but huilan's server is just 7 second. 
              Achieve reasonable results when apply max-margin method to CNN-DSSM model.
2016-04-21 : True DSSM model doesn't work well, analysis as below: 
               1. Not exactly reproduce DSSM model, because the original one is English version, I just adapt it to Chinese but after word segmentation. 
                  So the input is tri-gram words not tri-gram letter.
               2. Our dataset far from rich, because of we do not use pre-trained word vectors as initial vectors, we can hardly achieve good performance.
            : Request
               1. As we have rich pre-trained word vectors, maybe CDSSM or RDSSM corrected to our task.
               2. Different length of sequences seek to be fixed dimension vectors, just CNN and RNN can do such things, DNN can not do it by using 
                 fix length of word vectors
            : Coding done CDSSM. Test for it's performance.
               One problem : When you install tensorflow by pip 0.8.0 and you want to use conv2d function by gpu, you need make sure you had already 
                            install your cudnn's version as 4.0 not lastest 5.0.
2016-04-20 : Find reproduced DSSM model's bug, fix it.
2016-04-19 : Code mixture data model by less memory dependency done. Test it's performance.
2016-04-18 : Code mixture data model.
2016-04-16 : Code mixture data model, but face to memory error. Dr. Wang help me fix it.
2016-04-15 : Share Papers. Investigation a series of DSSM papers for future work. And show our intern students how to do research.
