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

Figure 6

Weights as given by the bottleneck neuron corresponding to using a second candidate PMT, and the most important PMT, , as identified previously for (a) and (b) . is whitened in each figure. In each of the heatmap, the circled PMT, , corresponds to the largest weight amongst the remaining 191 PMTs given that the first important PMT has been identified with the bottleneck DNN.
