STEP 0: Setting the DSTC 5 data

Make a directory 'data', then put the DSTC5 data set in 'data'.

STEP 1: Generate data for training

Generate the training data.

$ python data_generator.py  

After then, there will be created 5 pkl files.

• dstc5_general.pkl: dumping the slot, slot value vectors
  
• dstc5_train.pkl: dumping the training data
  
• dstc5_dev.pkl: dumping the validation data
  
• dstc5_dev_acc.pkl: dumping the accumulated validation data (accumulate the previous utterance)
  
• dstc5_test_acc.pkl: dumping the accumulated test data (accumulate the previous utterance)
  

STEP 2: Training

It takes 7 arguments. Example of the implementing code is like below.

$ python train.py -l 100 -lr 0.005 -e 100

• -l: the number of lstm units (default = 100)
  
• -lr: learning rate (default = 0.005)
  
• -dr1: first dropout parameter (default = 0)
  
• -dr2: second dropout parameter (default = 0)
  
• -e: the number of epoch (default = 300)
  
• -t: type of dstc (4 or 5, default = 5)
  
• -c: criteria of finding threshold (accuracy or fscore, default = accuracy)
  

After then, there will be created weight file with named 'dstc5_lstm#l_lr#lr_dr#dr1_#dr2.h5' (ex. dstc5_lstm100_lr005_dr0_0.h5)

STEP 3: Predict with finding threshold

It takes 7 arguments. Example of the implementing code is like below.

$ python predict.py -l 100 -lr 0.005 -e 100 -th

These arguments are same with STEP 2.

• -l: the number of lstm units (default = 100)
  
• -lr: learning rate (default = 0.005)
  
• -dr1: first dropout parameter (default = 0)
  
• -dr2: second dropout parameter (default = 0)
  
• -e: the number of epoch (default = 300)
  
• -t: type of dstc (4 or 5, default = 5)
  
• -c: criteria of finding threshold (accuracy or fscore, default = accuracy)
  

One more argumets here.

• -th: to decide the threshold and make a file for threshold (default is no -th)
  (You have to add -th when you implement predict.py first time.)

After then, there will be created 2 json files like below.

• dev_dstc5_lstm100_lr005_dr0_0_accuracy.json
  
• test_dstc5_lstm100_lr005_dr0_0_accuracy.json
  

STEP 4: Make a result

For validation result,

$ bash dev_run.sh dev_dstc5_lstm100_lr005_dr0_0_accuracy.json

For test result,

$ bash test_run.sh test_dstc5_lstm100_lr005_dr0_0_accuracy.json

Then, you can see the result and there will be created the result files.

• dev_dstc5_lstm100_lr005_dr0_0_accuracy.score.csv
  
• test_dstc5_lstm100_lr005_dr0_0_accuracy.score.csv
