Deep Learning the Effects of Photon Sensors on the Event Reconstruction Performance in an Antineutrino Detector

Figure 4

Weights as given by the bottleneck neuron corresponding to each PMT for (a) and (b) using the bottleneck DNN. In each heatmap, the circled PMT corresponds to the largest weight in the heatmap amongst all the 192 PMTs, indicating that it is the most heavily used PMT in the DNN during the vertex reconstruction.
