## Architecture

### Objective Functions



    

  
The objective functions (losses) for training ADAE [1].



### ADAE architecture



    

  
The architecture of ADAE.



### Graph in TensorBoard



    

  
Graph of ADAE.



### Problem Definition



    

  
'Class-1' is defined as normal and the others are defined as abnormal.



## Results

### Training Procedure



  


    

    

    

  

  
Loss graphs in the training procedure.Each graph shows the generative loss, and the two terms that make loss-G.





  


    

    

    

  

  
Loss graphs in the training procedure.Each graph shows the discriminative loss, and the two terms that make loss-G.





    

  
Restoration result by ADAE.



### Test Procedure



  

  
Box plot with encoding loss of test procedure.





  


    

    

    

  

  
Normal samples classified as normal.


  


    

    

    

  

  
Abnormal samples classified as normal.


  


    

    

    

  

  
Normal samples classified as abnormal.


  


    

    

    

  

  
Abnormal samples classified as abnormal.
