KERAS checks (12/12/18)

The plots below show results from KERAS run via TMVA.
The configuration was 2 input nodes, 64 hidden nodes(relu),
2 output nodes(softmax).  

 Fig 1  Response signal - linear
 Fig 1a  Response signal - log

 Fig 2  Response background - linear
 Fig 2a  Response background - log

 Fig 3  Selected signal and background
 Cost function  0.0137473084407

 Fig 4   Jetnet for comparison.  Note response plots.
 Cost function    0.0259017926

 Comment:  rms of response plots underestimates the cost function (squared error).

 Conclusion:  KERAS gives  a better separation of signal and backgound than do 
              Jetnet  and MLP.
