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.
