 ## How to use
-This system includes two parts: browser side and machine learning side. The machine learning side calculates interpretable information of DTM set by researchers based on users' input, as well as predicted value of input after reordering by end user. The machine learning side can be run directly and offers partial interpretability. The code is available  under machine learning branch: https://github.com/505025234/OrderVis/tree/machine-learning-side .

 ## Critical Interface
   - 1.The researchers need to import target model in interface StartPro, and run the machine learning side through this interface.  
   - 2.While the program is running, the machine learning side will call interface oriInputSigni to calculate interpretable information of DTM.  
-  - 3.Interface getPredict is set to provide prediction value of input reordered by end user.  
-  - 4.If you want to use our system to trace training data, retreating your data is essential, you should use interface ReadFile to import your model and read your data into cash. The details of usage will show in branch maching learning side.  
+  - 3.Interface getPredict is set to provide end-users with predicted values of reordered inputs.  
+  - 4.If you want to use our system to trace training data, it is essential to pre-processing your data. You should use interface ReadFile to import your model and read your data into cash. Details of usage will be shown in maching learning branch.

 ## Main function
-### machine learning side (back-end)
-  - 1.ReadFile and PreTreat are used to pretreat training data. (Pretreatment is unnecessary. However, it must be done before you establish the machine learning side server if you want to trace your train data.)  
+### Machine learning side (back-end)
+  - 1.ReadFile and PreTreat are used to pre-process training data. (Pre-processing is not necessary. However, if you want to trace your training data, it must be done before establishing a server on the machine learning side.)  
   - 2.ServertoStart and StartPro are used to import model which will be interpreted.  
-  - 3.ReorderByGroup is used to calculate local interpretability and glabal interpretability of model; GetDiffer is used to catch critical order line with genetic algorithm; GetPartner is used to trace train data(it cannot be used without pretreatment).  
-  - 4.GetPredict is used to calculate prediction value of input reordered by end user.  
-### browser side (front-side)
-  - 1.GetInput will communicate with the machine learning side and invoke ReorderByGroup, GetDiffer, GetPartner. it will show interpretable information of DTM graphically.  
-  - 2.When end user interact with the system in way of dragging components or token, DragData will be called and communicate with the machine learning side. DragData will show prediction value of reordered input.  
+  - 3.ReorderByGroup is used to calculate local interpretability and glabal interpretability of model; GetDiffer is used to capture critical order line using Genetic Algorithm; GetPartner is used to trace training data(not available without pre-processing).  
+  - 4.GetPredict is used to compute predictions for inputs that have been reordered by end-users.  
+### Browser side (front-side)
+  - 1.GetInput will communicate with the machine learning side and call ReorderByGroup, GetDiffer, GetPartner. It will graphically display the interpretable information of the DTM.  
+  - 2.DragData will be called and communicate with the machine learning side when end-users interact with the system by dragging components or tokens. DragData will display predicted values of reordered inputs.
