Ich habe eine Rastersuche für eine Reihe von Parametern eingerichtet. Ich versuche, die besten Parameter für ein neuronales Keras-Netz zu finden, das eine binäre Klassifizierung durchführt. Die Ausgabe ist entweder eine 1 oder eine 0. Es gibt ungefähr 200 Funktionen. Als ich eine Rastersuche durchführte, bekam ich eine Reihe von Modellen und deren Parameter. Das beste Modell hatte diese Parameter:
Epochs : 20
Batch Size : 10
First Activation : sigmoid
Learning Rate : 1
First Init : uniform
und die Ergebnisse für dieses Modell waren:

Also habe ich dieses Modell mit mehr Epochen (150 davon) wiederholt und dies sind die Ergebnisse, die ich erhalten habe. Ich bin mir nicht sicher, warum das passiert, ist das normal oder was mache ich falsch?
