performance of NN

Performance of NN. Data pipeline and input structure.

  • TensorFlow with Keras
  • Training and testing based on simulation for: CERN 18
  • run 403, 7 GeV/c pions @ 20-140 degree polar angle

Data pipeline:

Index based data translated into full dimensional tensors. Example of one event @ 20 degree polar angle. X dimension has size of 532 (512 for channel ids and 20 to encode momentum/angle id)

Performance of 1-layer dense NN in comparison to Time Imaging. Each angle was trained with separate NN:

Efficiency:

One common NN trained on 20 and 140 degree data:

One common NN trained on 20,30,40 ... 140 degree data (10 degree step):
